Today, I’ll test my Beeman R1 air rifle for velocity, plus show you the differences between the standard Rekord trigger and the special match Rekord trigger. Before I get to the velocity figures, however, let me give you a brief history of some of the many tunes that have been in this gun.
After 1,000 shots were on this rifle, it was shooting Crosman Premiers at an average 770 f.p.s. The rifle took 46 lbs. of effort to cock and shot with a little buzziness, indicating the powerplant had some looseness.
Following that test, the rifle went through a series of tunes that are way too numerous to cover here. One that’s of interest was the Beeman Laserization that was so popular in the 1980s and early ’90s. Beeman would do this tune for a price, or you could buy all the parts and do it yourself. I elected to do the latter.
The Laser seal came way oversized and had to be reduced to fit the particular gun in which it was installed. That was thought to be a superior way of tuning in those days, though today I see generic seals that work just as well without all the fuss.
I had a problem fitting the first seal, and it burned on one edge from excessive friction. I got a replacement and sized it a bit looser. You never want to lube a Lazerized rifle, as the special Beeman Laser Lube is the best stuff for friction. This lube is no longer sold. If you have a worn-out Laser seal, just about any modern generic seal can replace it with no loss of energy.
The Laser spring was weaker than the factory spring, making the rifle easier to cock. After I applied the tune and broke it in a little, my rifle averaged 765 f.p.s. with Crosman Premiers. Cocking effort was 37 lbs., which is an 11-lb. reduction for almost the same power. That’s significant!
The one thing I didn’t like about Laserization was the fact that the gun vibrated a lot more than before. That Laser spring fit the piston and guide so loosely that the only way to quiet the gun was to use Mainspring Dampening Compound on the mainspring — which subtracted velocity at the same time.
The absolute best tune I ever applied to the R1 was a Mag80 Laza Tune I got from from Ivan Hancock. It was a drop-in tune that included a buttoned piston and a long mainspring that came coated with something I called black tar in print the first time I wrote about it. After that, the airgun community seized on the term, and black tar became a product — though nothing that was ever sold separately was as viscous as the stuff on that Venom spring.
This tune took the R1 up over 22 foot-pounds with absolute zero vibration. It was so smooth I thought it had actually lost power. But the 50-pound cocking effort reminded me that the big spring was doing its thing. For reference, Crosman Premiers averaged 809 f.p.s. with this tune.
Unfortunately that spring was included in my Mainspring Failure Test, that left four different tunes cocked for one month to see the effects. The spring finally canted and was never as smooth afterward!
I also tested a gas spring made by Vortek. It was smooth and did make better than 20 foot-pounds with certain pellets, but it also took 50 pounds of effort to cock, so I have since removed it from the rifle. The gas spring put Premier pellets out the muzzle at around 790-795 f.p.s.
The tune that’s in the rifle now is a weak mainspring and a generic piston seal. Everything is moly-ed and I have used a touch of Black Tar on the mainspring to calm it down. Today we will all see what velocity the rifle currently develops with this tune, which can be researched in its entirety in the 13-part report titled Spring Gun Tune.
The first pellet I tested was that old standard — the Crosman Premier. I have given you the velocities for this pellet at various stages of the rifle’s life, so you can compare them to how it’s doing now. With the current tune the rifle shoots Premiers an average 743 f.p.s. The range runs from a low of 738 f.p.s. to a high of 751 f.p.s., so an extreme spread of 13 f.p.s. Given the pellet’s average 14.3-grain weight, the rifle produces 17.53 foot-pounds at the muzzle with Premiers. I noticed they fit the breech on the loose side, but were still what I would consider a good fit.
The rifle now cocks with just 33 pounds of effort, which is where I like it. It weighs 11 pounds on the nose, and you have to allow a little over one of those pounds for that big Bushnell Trophy 6-16 scope and mounts.
Next I tried RWS Superdomes, another domed pellet like the Premier but made of pure lead and just slightly heavier, at 14.5 grains. These averaged 742 f.p.s. in the test rifle and ranged from a low of 733 to a high of 748 f.p.s. So a 15 foot-second spread. At the average velocity this pellet produces 17.73 foot-pounds of energy at the muzzle. The fit was loose in the breech.
Then I tried the heavier 15.43-grain Gamo Hunter. This dome fit the breech loose but also varied a lot in the seating pressure required, which indicates variability in the size. They averaged 706 f.p.s. and ranged from 700 to 710 f.p.s., which is a tight spread of just 10 f.p.s. At the average velocity these pellets produced 17.08 foot-pounds of energy.
The final pellet I tested was the 15.9-grain JSB Exact dome. These averaged 696 f.p.s. and ranged from 693 to 701 f.p.s., so the spread was just 8 f.p.s. — the tightest of the test. The fit of this pellet was loose in the breech. At the average velocity this pellet produced 17.11 foot-pounds of energy at the muzzle.
I mentioned that the trigger in the R1 is a standard Rekord, and when I reported on the HW55 target rifles, I had mentioned that they all have special match Rekord triggers. Weihraiuch now calls all of their Rekord triggers match triggers, but back when the 55 was still being offered they differentiated between the trigger in that gun, which they called a match trigger and the one they used in every other sporting rifle. The latter was just called a Rekord.
This is the standard Rekord trigger that’s on my R1. Paul Watts gave me the smooth trigger blade to replace the Weihrauch grooved blade that comes on the trigger, but otherwise the trigger unit is stock. I have adjusted and lubricated it, of course.
The match trigger also has no provisions for a safety, in contrast to the standard Rekord. Target guns are seldom provided with safeties, as their shooters are expected to be cognizant of safe shooting at all times.
The match Rekord has an aluminum collar around the trigger adjustment screw that is used to lock the screw after adjustment. This collar is turned by hand-pressure, only, so it is knurled on the outside to provide a better grip. Let’s sample the R1 trigger against an HW55-CM trigger and see how they differ in use.
The R1 trigger breaks cleanly at 1 pound 1 ounce — a little lighter than the recommended 1 pound 8 ounces that the Beeman instructions used to recommend. You have to remember that I have shot this rifle extensively since it was new and I have worked on the trigger, as well.
The match Rekord in my HW55 CM breaks at 7 ounces, or just less than half of where the standard Rekord goes off. It is considered very safe at this low pressure setting, because of both the design of the Rekord and that fact that a target shooter will be handling the rifle.
The two Rekord triggers are dimensionally the same. The proof of that is my HW55 SF that is an HW50 with this trigger instead of the normal Rekord that’s found on the HW50s. Back when the 55SF was made, the HW 50 was a different model than today, but the same gun could accept either trigger.
Should you swap your trigger?
The question that always comes up when I tell people about these two triggers is why not just adjust a standard Rekord to have a pull weight equal to the match trigger? The answer is the match trigger isn’t designed to hold back pistons that are compressing powerful mainsprings like those found in an R1 — or even in lesser sporting rifles. And, if you were to install a match trigger in a sporting rifle, you would be doing the same thing. So leave the trigger that came with the gun where it is and be safe.
That’s it for today. Next we will look at the accuracy potential of this rifle.
