How to choose a PCP

by B.B. Pelletier

We got this request last week. A reader wants me to cover the applicability of various PCPs to different kinds of shooting, so that's what I'm going to do.

Low power for target shooting
There really is no choice with this first category. All modern PCP target rifles and pistols develop 6 foot-pounds or less, and PCPs are at the top of technology where target airguns are concerned. Pistols hover between 480 and 530 f.p.s., while rifles are usually around 580 f.p.s. The rifles represent a downward shift in velocities from the 1960s. Back then, it was considered good to develop between 600 and 650 f.p.s. Even though a modern PCP can easily get higher velocity, the makers don't do it because it isn't needed. They get additional shots, instead.

A subset of target air pistols are also used for airgun silhouette. No power modifications are made to these air pistols, as they already develop more than enough power to knock the heaviest silhouettes off their stands at the farthest range.

Field target rifles
Field target rifles are a very specialized niche within PCP rifles. While many competition rifles are being converted from 10-meter target guns (under 6 foot-pounds!), there are many more that are either straight sporting PCPs or modified sporters. The caliber is always .177, because it is the only competitive caliber for this sport - just as it is the ONLY caliber that can be used by regulation for bullseye target shooting. And, 20 foot-pounds is the upper limit for American field target rifles. That's not because of any rule, but because most clubs mandate that limit to prevent damage to their targets. Power, as you know, also means velocity, and in .177 caliber, 20 foot-pounds means a very fast pellet. For example, it's a 10.5-grain pellet traveling 926 f.p.s. That kind of energy concentrated on a small area on a steel target actually burns away the steel when the lead pellet flashes to incandescence. After several thousand hits in close proximity, the steel will have developed deep pits. Club targets get that kind of use in two or three seasons of brisk competition.

British field target shooters are restrained to below 12 foot-pounds of muzzle energy, so they will shoot in the 800 to 825 f.p.s. range. Their guns are easier on the targets and on their own mechanisms. When the Brits come to America to compete in field target, they may tweak up the velocity of their rifles, but seldom do they get up as high as American shooters. They understand that velocity alone does not make a good FT rifle.

General shooting and hunting
This is where all restrictions come off the rifles and the field is wide open, but there are still categories of guns to be considered. Those rifles that develop 20 to 30 foot-pounds, for instance, seem to be the most popular general-purpose air rifles. Let's look at the FX rifles as an example. Made in Sweden by designer Fredrik Axelsson, the FX PCP rifles seem to cluster around this energy level. That's not because Axelsson can't make them more powerful - because he certainly can! But he has found that this is the ideal energy level for a good all-around PCP. Because FX makes the rifles for Webley and others, they have a huge influence on the airgun market.

AirForce is another maker that is clearly not restrained to any power limitations, yet two of the three rifles they make, the Talon and Talon SS, fall within the 20 to 30 foot-pound power range. So do most rifles from Logun, Air Arms, Daystate and Falcon. Yes, these companies may have one or two rifles that are either more or less powerful than the 20-30 foot-pound range, but if you examine the numbers of models that do fall within that range, you'll see that the evidence is overwhelmingly in favor of that power range.

.177 and .22 are at different ends of the power range
Now, it's time to practice what you've learned from this blog. You know that power relates to projectile weight and velocity, so it should come as no surprise that the .177 rifles hover near the low end of the 20-30 foot-pound range, and the .22s occupy the middle and upper limits. That's because of the accuracy factor relating to a top velocity of around 900 f.p.s. While there are no absolutes as far as accuracy is concerned, you will find that manufacturers know this relationship very well and build their rifles to take full advantage of it. That's what makes the next and final category of rifles so special.

Smallbore PCPs that develop more than 30 foot-pounds
These are the big guns, so to speak. They don't begin right at 30 foot-pounds, as a general rule. They usually start around 45 foot-pounds and go up to as high as 80 foot-pounds. I am not saying there aren't ANY air rifles that develop 38-40 foot-pounds, but that is not a popular power level. It seems to me that once a maker exceeds 30 foot-pounds, they try to get into the high 40s or higher. Here we leave behind .177 and .20 caliber, for pellet weight is needed to develop the awesome power these rifles produce. In .177 and .20, the pellets become too long to stabilize in flight, so they cannot be accurate at long range. You need pellets weighing 30 to 50 grains for these power levels, and only .22 and .25 calibers have them.

This is where the Career III and the Saver 7000 hang out. The Career 707 often spits out heavy .22 pellets at an energy above 60 foot-pounds! The AirForce Condor is king of them all! Not only does it produce power in excess of 65 foot-pounds, but it is the only PCP that can do so for a long string of shots! Plus, the Condor's power can be easily dialed back to 19 foot-pounds when needed.

NOT for general shooting!
I cannot tell you how many shooters I've spoken to who were dissatisfied with their choice of rifle because they picked one of these bruisers, only to discover that it's just as loud as a .22 rimfire! For some reason, they thought it would be quiet like their Diana RWS 34, but that's not the case. Buy one of these airguns only for hunting. If you want a flexible, all-around PCP, look to the more popular 20-30 foot-pound guns.

We shoot airguns for enjoyment - not for bragging rights. The world's most powerful air rifle is a pipsqueak compared to a centerfire rifle caliber, so get a gun you'll enjoy shooting all the time.

So will the condor sound loud regardless of pellet weight? Because in my gamo 1250 .22cal I at least have noticed a difference between weights.

Robert,

Yes, the Condor is loud regardless of pellet weight. Caliber does make a difference, though. The .177 is not as loud or as powerful as the .22.

only in pcp shooting or also with springers? If it's safe for spring gun shooting where might I find some FP-10?

BB,

I have a moderator on my Condor that I purchased from another airgun supplier. It GREATLY reduces the report. Now it is quiet enough for neighborhood shooting. If the rifle is adjusted to keep the velocity of the pellet from breaking the sound barrier the noise is something like a car door slamming. Even on full power!

Great review! Thanks...

Any chance you could drill down one more layer and disect the 20 to 30 foot-pound sporting choices?

Jason, where did you get that moderator ? Is it legal in the US of A without all the bureaucratic red tape from BATF ? Wish you could email me but I'm not sure I'm allowed to post my address here.

Leon,

Yes the moderator is legal in the US, w/o any special permit or ATF stamp. I would be happy to tell you where I bought it from, but I don't think it is proper to do it here (promote another airgun supplier on Pyramyd's blog). I do believe it is okay for you to post your email address here, ( Is it BB?) and I will email you the info. Thanks.

Jason

Pellet oil,

I don't recommend FP-10 in spring guns. Try Whiscombe oil. I gave the formula for it a couple of days ago. Two parts Hoppe's Gun Oil, one part STP Engine Treatment.

Get FP-10 and Hoppe's at a good gun store or from Midway - www.midway.com.

Yes, I think it's okay to post email addfresses. And I agree, we shouldn't be sending Pyramyd's customers to other dealers via their blog.

Jason - thanks for your quick reply. Good point about promoting on a competitor site. Would NOT be cool if it was MY business's site.

BB - besides posting email addresses here, is there any other way we can get them so we can write each other directly ?

Or maybe you could do a blog entry about this item, since it seems to be legal and possibly something a bunch of Talon and Condor owners or wannabe-owners are thinking about, ie, the noise issue ? Maybe suggest to Mr. Ungier that he get some in stock too ?

Drilling down one more layer,

That is a real problem for me. I find the performance of a $1,200 Logun sporter to be the same as a $500 Talon SS. And the same for a Falcon, FX, Daystate and so on.

What differentiates these guns is their features. Some people hate the looks of the Talon SS. Others are attracted to it because of the looks. But the rifle is just as accurate (and obviously just as powerful, since we are talking about the 20-30 foot-pound range) as the Logun, the Daystate, the FX and the Falcon.

I'm not saying all the guns are the same! The Talon SS requires a strange hold, with the tip of the butt high on the shoulder. The Daystate is more conventional. The triggers on the Logun and Falcon and Daystate are better than the trigger on the Talon SS or the FX. So there are choices. But they are personal preference choices, rather than substantive differences.

Having said that, did you notice that I compared two spring rifles directly in today's post? I did so because I feel the performance of one is ahead of the other. But I'd be hard-pressed to prove that it's worth the difference in cost!

Leon, Jason and anyone else interested in silencers,

It's not as easy for a business like Pyramyd Air to get involved in the sale of airgun silencers. You can call them moderators, or even cabbage if you like. If BATF&E calls them a silencer and they fit the legal description for a silencer, then that's what they will be when the charges are written up.

The places that sell airgun silencers are hobby businesses. They come and go over the years. And sometimes they go because they've stepped over the line and had a visit from the government.

When BATF&E arrives at your business, they are humorless men who advise you of the law and explain your options. In most cases, the business owner decides on the spot to cease and desist selling silencers (or moderators or sound attenuation devices or anything else he might have been selling up to that moment) and life returns to normal.

I know of an arrest that was made for posession of unregistered silencer, but charges were never pressed. The device was confiscated and everyone went on with their life.

For this reason, the owner of a large, ongoing business like Pyramyd Air has to be triple careful about stepping over the line of legality. I don't know the specifics of the moderator Jason is referring to, but the simple test is that if it can be attached to a firearm and if it then lowers the sound of that firearm by one decibel for just one shot, it's a silencer and must be registered. If not, it is okay to sell.

You will notice that in today's posting, I pointed out that the TX200 Mark III has a baffeled barrel shroud. That shroud has been examined by BATF&E and found to not violate the silencer law in any way. AirForce Airguns did the same with the Talon SS. They actually have a letter on file from the old BATF stating that the Talon SS does not violate the law.

When your business grows to a respectable size, you have to make decisions much more carefully because many more eyes are now watching every move you make.

I am not an employee of Pyramyd Air and my remarks in this blog are my own and not connected with their business in any way. I say this because I want you to know I am not speaking for Pyramyd Air on this issue.

BB and fellow readers,

I agree with BB, one must be careful about what sound attenuating devices they put on their airguns. I want to add that I take laws and my freedom very seriously. In no way, did I mean to condone the violation of ANY LAW! Thanks.

Does anyone know if the Career III 707 (single tube) is available
in the US? Is the Career Ultra available in .22 here in the US?

Here's some pics:

ihave a new condor 22 cal, is their any one who can put a stoughter spring in my condor. i dont get maxumun power with it at 200 bar pressure, only at 150 bar, 200 bar is to much for the spring to open the air reserve bottle, verry disipointing. help Jerry. jerryjpersinger@hotmail.com

bja,

A stronger hammer spring won't help your gun. You are just getting maximum power at a lower fill pressure. You are still getting all the shots a Condor gets and all the power a Condor gets.

However, if you just want to raise the fill pressure without affecting the power por the number of shots the gun gets, contact AirForce. They can adjujst the valve so it goes to 3,000 psi.

can all pcp's be filled with a pump instead of a divers tank?

 
At May 31, 2008 8:25 AM, Blogger B.B. Pelletier said...

There are a few PCPs that need a fill in the 300-bar (4350 psi) range. No hand pump goes that high. The AirForce hand pump (also found on the Benjamin Discovery) is the leader, at 3,600 psi.

The number of guns needing 300 bar air is very low, however. Only Walther markets them, and Walther PCPs are not a large part of the market.

hi, i have a couple of questions. 1. Will there be a 2008/2009 shot show, and when will it be? 2. For pcp's, some people say that there might be a thought for Crosman to produce a multi shot pcp, will that be true? ok, thanks.
