JSB 546387-150 Jumbo Exact Beast Air Gun Pellets .22 Cal, 33.95 Grains, 150ct

Best ammo we tried so far. Great groups with our Beeman chief 2 plus.

Can’t say what your particular rifle likes, but swam magnum pro shoots best with the heavy. Haven’t tried short distances yet, but at 40 yards they’re incredibly accurate and consistent. Can only assume at shorter distances, they’d be just as accurate. Probably my go to pellet and weight

Sounds like slugs when they hit! Accurate as hell to.

I got one can from this seller and it arrived all banged up, the pellets were deformed as if they were thrown during shipment. Sent them back and got a new set. This one seemed a lot better. Still there were some pellets that were deformed. I decided to give them a try and to my surprise the performance was quite good. I am comparing their performance to a brand new set I have in perfect conditions, shooting at about 30 to 35 yards, they perform really well. So maybe don’t get discouraged by the deformities. Also I checked the inside of the barrel and it is flawless, so I think the deformities happens because they are very soft.

best pellets on the market. clean and consistent.

JSP Exact is supposed to be the de facto product standard by which all others are judged; not any more... I ordered and received a tin min-June. In my excitement I just started loading pellets into my magazine and shooting without any inspection. I mean, why should I? These are supposed to be some of the best pellets on the planet! Pellets were flying all over the place and assumed my gun needed a little time to adjust to my feeding it new pellets. After 20 shots, I decided to grab my reading glasses as I am blind close-up. I couldn't believe what I was seeing! The amount of skirt damage was so significant, I would have been lucky to get 1:10 usable pellets out of my 10 round magazine. I would be hard-pressed to find usable pellets. Also, there was significant seaming on this set. I had no choice but to return this tin and get another one. I just assumed that somebody did a switcheroo because there is no way these came from the factor like this... Right? I sent these back and got a new tin by late June. Well, a month has gone by, now the end of July, and I am finally getting around to shooting these, and WTF? Here we go again! This new tin has the same skirt damage problem! The seaming was definitly better, but that alone isn't going to make them usable. I would estimate there are 3:10, maybe 4:10 usable pellets out of this tin. I will be lucky to get 75-100 usable pellets out of this 250 ct tin. I was looking to make these my new daily driver, and with this atrocious lack of quality control, it just isn't going to happen. I may try these in the future, but until they get this sorted out, I absolutely canNOT recommend them. Crosman Premiers have better QC than this... Off to find another pellet with a good ballistic coefficient to use as my daily driver.

I used these and other pellets in a .22 cal Benjamin Trail NP XL Air Rifle air rifle at 10 meters after the gun was broken in with a couple hundred shots. I compared accuracy (and to a lesser degree penetration) of the following pellets: Skenco Heavy Long-Range .22 Cal, 16.7 Grains, Pointed, Lead-Free, 90ct JSB Match Diabolo Exact Jumbo Heavy .22 Cal, 18.13 Grains, Domed, 250ct RWS Meisterkugeln Standard .22 Cal, 14.0 Grains, Wadcutter, 250ct Crosman .22-Cal Hollow Point Hunting Pellets . The RWS Wadcutters were the most accurate pellet in the group. Their flat-heads had a great ability to cut perfect circles in paper targets as they were intended. Some people have stated these would not be good hunting pellets although I certainly would not want to be a rabbit on the other end of the barrel. At 10m I was able to hit a quarter (or sometimes a ChuckeCheese token) in 8/10 shots. Interestingly, these and all the pellets would make indentations in the coins and basically melt/deform into the coin. The JSB Match Diablo Exact Jumbo Heavy domed pellets were very accurate. At 10m I was able to hit a quarter in 6/10 shots. These pellets penetrated slightly deeper into wood than the RWS Wadcutters and Crosman HP's. The Crosman HP's were nearly as accurate as the JSB's, having hit 5/10 shots. These are good pellets for the money if you are concerned about cost. The Skenco's were by far the least accurate (least consistent). In 10 shots I could not hit a quarter and they mapped an approximately 6 inch center-to-center. These did exhibit the deepest penetration. For instance, they penetrated approximately 100% deeper in the 2x6 douglas fir boards used as backing for my targets. Based on their characteristics, I suggest these pellets only be used as a novelty item. Perhaps the only good use of these pellets would be to kill a larger animal from point-blank range where accuracy is not necessary. Another oddity of these pellets is that they do not fit snugly into the bore. The front of the pellet is an extremely hard alloy and the back 2/3 is red plastic. At the skirt-end of the pellet the plastic is flat and slightly larger than the rest of the bullet (similar to the rim of a .22Cal.LR rim fire cartridge but even thinner). I have described this oddity because typical loading techniques with a break barrel pellet rifle can result in the pellet falling out when you raise the barrel back into position following placement of the pellet into the bore. I unfortunately dry-fired the gun 3 times before realizing what was occurring. Fortunately I have not seen or felt any differences in the gun following this mishap.

Heavy, accurate and packs a devastating blow to small game…!

The pellets come damaged ,and that is like buying a car with no tires, not really any good to you.

good

I primarily use these 25.? grain cylindrical lead pellets, or "slugs" with my vintage 1976 .22 cal. Crosman 1400 PumpMaster Pneumatic Air Rifle, and my .22 cal. Crosman P1322 pneumatic air pistol. I have chronographed these slugs with my P1322 pistol and they consistently average around 375 fps!!! I have yet to chronograph them with my 1400 Pumpmaster rifle, but I expect higher muzzle velocity due to the higher power output of the pneumatic air rifle compared to the pistol.

IMO best quality pellets for the money. Super accurate.

Excellent
