Page 5 - JSB Match Diabolo, .177 Reviews

From what I have shot, these are pretty consistent in accuracy. Size and shape have been consistent also

Screw on Cap

These are the first JSB'S I have used in my TX200 and HW97 and they are great.

Nothing

A great buy.

1. The tin has foam padding in the bottom and the lid to help reduce pellet damage. I've gone through nearly an entire can and have found no noticeable damaged to any of the pellets. 2. The 4.52 mm head size and soft lead fit extremely well in all 3 of my .177 air rifles (Gamo Hornet Maxxim, QB78, Stoeger X3-TAC) 3. The 8.44 gr weight is a great all-around weight for most .177 break barrels and CO2 guns. 4. The consistency of each pellet leads to great accuracy.

I prefer a screw on lid and a tin that is a little more heavy weight to prevent damage.

I purchased these along with a tin of Air Arms Field (8.44 gr) and H&N Sniper Medium (8.5 gr), to try in my Gamo Hornet Maxxim and QB78. These are the first premium pellets I have purchased for these guns. Prior to these, I tried the following pellets:

Crosman Hollow Point
Crosman Lights
Crosman Ultra Magnum
RWS Superdome
Gamo Hunter

The Air Arms Field performed as well at the initial 10 yard test, and nearly as well at 25 yards. However, the JSB Exacts give me very consistent .5"-.6" groups at 25 yards in with my Gamo Hornet Maxxim, and .5" groups with my QB78 at 25 yards.

Each time I load one of these JSB Exact pellets, I get the feeling (confidence) knowing I'm going to hit what I am aiming at.

Pellets look clean and uniform and are consistent in weight.

Put correct size in tin. Ordered 4.52 and all I measured (50?) were way under size. 4.46 to 4.49 mostly.

Of the 10 different tins of pellets I have, these are the loosest ones in the breech. Almost fall in without needing a push in to seat. Maybe I just got a bad batch or mixed up tin?

Best accurate pellet on the market.

Screw on lid.

The old pellets no longer available were the best pellets available for my CPC Pistols. Pellets were clean and weights accurately as advertised.

Go back to the prior molds or sizing dies.

These new pellets ordered do not work well in my Marauder or Steyr LP 50 CPC pistols. The head space of the pellets are smaller than listed and fit loose in the barrel and magazine. When pellets are put into Steyr magazines some of the pellets will fall out when the magazine is tuned upside down.
The pellets do weigh out correctly which makes me believe there is a sizing problem in production.

Tested for accuracy and penetration against approximately 30 other pellets in my Air Arms S 510. Proved to be the most accurate plus penetrated the greatest distance while perfectly mushrooming.

Nothing

The best lite weight pellet money can buy, as well as AA!!!!!!!!!!!

Your gun deserves the best, buy these.

These are not the same 4.52mm JSB Diabolo Exact as I had bought before to use in my D34. Because of that there was very little to like about them. However, even though they were very disappointing in my D34, they were OK (not great) in my D48/177.

I would make them to the original spec. These are extremely undersized. Most measured 4.46mm or less in head size.

These pellets no longer work in my D34. The original version of these pellets could be counted on to produce near single hole patterns at 10m. These produced shotgun type groups in comparison. Their weight was accurate at 8.44gr as the originals pellets I tested at the same time. However, their head size measured on average a minimum of .02mm less than the original version of this pellet. They are very loose in the breech of my M34 So unless you have a very tight bore the blow-by on these has a adverse impact on their accuracy. I will not buy them again for my D34 until JSB corrects the undersize condition. Fortunately, being loose in my D48 did not hurt their accuracy and as such I will not have to go though the return process with PA.

Nothing. These were excellent pellets before they changed them. My Diana 34 could always put 5 shots in one hole at 10m. Those days are gone.

Return to the original JSB 4.52m pellet.

I just bought 4 tins of these pellets. All 4 tins were marked with the same lot # 45450016. Previous versions of this pellet provided extreme accuracy in my D34 as mention above. I was expecting the same from these but my targets at 10m looked like they were shot with a shotgun. With these pellets my 10m varied from 3/4" to 1.5" ctc! I tested a few of the old version to make sure I didn't have a gun problem and they averaged less than .25" ctc. I then checked the weight and head size. While the weight of both versions was virtually the same the head size of this latest batch JSB 8.44 grain pellets was .002 to .003 undersized from the older (in my case more accurate) version of this same pellet. I only buy these for there accuracy and this purchase I will never waste my money on these pellets again until I see reports that they are no longer undersized. Just beware these are not the pellets they use to be if you like them in the past.

These are fantastic in my Walther Terrus. Super accurate!!

nothing

Very consistent pellet, shoots great through my Benjamin trail NP XL ..I will buy more

Like others have said. I wish these pellets came in a tin with a screw on, off lid..even if it raise the price a little I would still purchase them. Provided quality doesn't change.

Great pellet accuracy for my .177 Benjamin Marauder.

Larger quantity per tin/box (I shoot a lot).

Every gun/barrel has it's favorite pellet so try a few different ones.
Unfortunately I didn't notice that this pellet was on backorder so I had to purchase a tin from another vender to make sure I had ammo for my next field target match.

My Gamo Silent Stalker Whisper IGT rifle shoots like a laser with these things. I get sub quarter sized groupings at 35 yards and the only reason the group is that big is because my hands shake. Takes down pests swiftly and humanely with a single head shot. Very good for backyard pest control if you live in a neighborhood because they seem to dump all their energy on impact and don't just zip through the animal and keep going.

Every gun has its own pellet preference. Yours may not like these. Try each of the different weights in your gun before you give up on the JSBs! They make a quality product. It's worth a couple of extra bucks to have ammo you can shoot with confidence when dealing with rodents.

Fairly accurate in my Diana 34.

Pellets are too loose and fall out of the breech. This can result in a dry fire.

These used to be my favorite pellets for my D34. For some reason, the pellets fit too loose in the breech and fall out. I also started to get fliers with these pellets. I have since switch of H&N FTT.

The salesman was very knowledgeable and recommended this pellet. It shoots the best in my RWS 48. This is good for hunting and target shooting. My groups improved drastically after beginning to use this pellet. I will not use anything else.

Nothing it shoots great.

I was using Crossman pellets before I used the Diablo pellets. It improved accuracy significantly.

They were the best pellets I used prior to February 2016.

Put them back the way they were.

I air gauged the head sizes of 10 tins of these from February 2016 and they were all way small compared to prior purchases. I am giving those to my grandkids and friends who don't care. I thought there was a production problem. So I just ordered 5 more tins, never again I am done. Same results as the other 10. They changed something, new dies probably. I will try them again in 5 years.

This is the pellet most preferred by my Weihrauch 50S, 35E and 77K.

Nothing, make them cheaper .... Ha ha ha

JSB's are probably the best pellet brand made and fit a wide range of guns, however they can be pricey.

Great pellet for my Weihrauch 35E, 50S or 77K.

Nothing.

The pellet also shoots well in my BSA R10 and BAM B50/B51. I usually use at least the JSB 10.34 grain in the PCP's, but the 8.44's work too.

That would be the many positive reviews of JSB pellets here and elsewhere. I like things that have a good reputation.

Pellets should be made to specs. My pellets were not 4.52 mm as it says on Pyramyd's listing but much smaller.

I have tried two tins of these, the first one about two years ago, the second one just now. First thing I noticed was the extremely loose fit in my Benjamin Trail NP with pellets from either tin. There is no resistance whatsoever when I put the pellet in. I have to be careful when I flip the barrel up or the pellet may fall out. I measured head size with a pellet gauge and these guys are checking out at 4.46-4.48 mm. After firing there is smoke in the barrel reminiscent of a dry-fire (just not as much smoke). That means these pellets may seriously damage my gun.
