The consistency of the size and shape.

Packaging? I have had a rather significant number of pellets with deformed skirts out of this one tin. Admittedly they were all on top, and after discarding (about 15 to 20) the deformed ones, the rest (so far) have performed flawlessly.

My Crosman Vantage NP absolutely LOVES these pellets. The only pellets that even come close to the performance of the 7.33gr is the 8.4gr JSB's...but the 7.33's are better (in my gun). The fit of the JSB's is consistently better than any other pellet I've tried to date, and the patterns I shoot with them at 20 yards is the tightest yet (under 3/4" ctc). I can't wait to get a Chrony to see what my velocity is like.

For some reason this pellet produces the highest velocity and best accuracy in almost all of my Weihrauch guns.

It is a little pricey.

Very good pellet!

This pellet previously has performed very well for me. The grouping was the best of any pellets I have shoe through this gun. The pellets out of this tin that were acceptable have also shot well.

On this tin, the quality is NOT there. So far on my first 200 shots (yes, I counted) I had 111 deformed pellets. These were not from rough handling, as the pellets have casting problems. the pellets look like they ran out of lead when casting the pellets. On my rating, since only < 50% of the pellets are usable, they only get two stars. Value and shape only get one star.

This is the first tin of this weight I have ordered, I usually go with a heavier exact pellet, and they have all been fine.

Consistency - only 1 pellet out of the first 500 was damaged. Shape - the Semi Dome design seems to fly true and created a "clean" mark on the paper target. Accuracy - after switching to these Pellets no shots have been out of the "Black" Packaging - with the way these pellets were packed and shipped there is very little change they could ever be damaged in shipping.

Nothing

Purchased for my son who is a 3 Position Novice Shooter, shooting less than 6 months. He is shooting an Air Force Edge with an Adaptive TS-1 sight.

A whole tin of fliers! Forget "Bullseye Bucks", I should get Frequent Flier miles!!

These pellets were all mostly all undersized at the head. (1 to 2 thousandths smaller than the 8.4 grain JSB) Almost every bench-rested shot was a flier! I reloaded with the 8.4 grain version JSB and immediately returned to tight, 3/8" groups at 20 yards.

I tried these because the 8.4 grain was back-ordered. I feel cheated to pay good money for pellets that are absolute junk.

I've liked the .22 JSB pellets so I decided to try these for my IZH pistol. They shoot great and are very accurate. They are also easier to load than the wad cutter style.

JSB quality and accuracy. Great for co2 pistols and lower power rifles (like gamo recon). My preferred pellet in my recon and crosman 357 pistol.

They shouldn't cost more than JSB pellets that weigh more.

Skirts are more apt to dent due to less weight/lead. Fits a bit loose in some clips.

Came with foam padded top. No dented tails. Get 4 cans it's much cheaper. Great price.

I ordered 2 cans of 7.33 grain RS Diabolo and 2 cans of 8.4 grain Diabolo from JSB. When I opened the package, I thought that there was a mistake. All 4 cans had same color and identical label design. The difference between 2 labels was that 7.33 had RS on the label and weight. Very confusing!

My Beeman 100 springer doesn't like them. The power rating for it is 660 feet per second. At about 15 yards, the grouping for 7.33 grain is about 3 inches. When I shoot the 8.4 grain all the pallets are almost dead on at the same distance. Comparing to the 8.4 grain, the 7.33 is shorter and the hollow end is deeper, which I think produces instability. I will stick with 8.4 grain. See my review for them.

Very good quality and accuracy.

Some guns like the lower grain weight, some don't.

FYI chrony results 5 shot avg fps: crosman 357= 460, gamo hornet= 949. Best pellet for my crosman pistol 357.

Very consistent, no seams. The perfect pellet from lower powered airguns to gain a little velocity over the 8.4 gr. version.

As with many quality products, I wish they were more affordable.

These are the favorite hunting pellets in my Crosman 1377, Daisy 953, and Crosman 66. Very accurate and about 50 fps faster than the 8.4 gr.

work great in a rws shutze. very accurate.

superb quality control. each pellet is exactly like the others permit precise placement of each shot.

not a thing.

Uniformity, lack of seams, accuracy, fit in gun chambers

Add some alloy, so they will shoot well in Marauders. :) Since these are pure lead, I think what's happening is that the skirts are deforming just the slightest bit as they leave the barrel, then clipping the baffles, destroying accuracy. That's my theory anyway.

If you're looking for the best domed pellet under 7.9 gr., this is it. Best energy retention, best uniformity, best accuracy. In pumpers, CO2 guns, and low-medium powered springers, this pellet is just fantastic. It even gave top accuracy out of my Stoeger X20, which shoots them at 926 fps. (tied, accuracy-wise, with Crosman Premier Lights, and Heavies, better than the 8.8 Exacts) Having tried some of the more expensive pellets in this class, like Beeman/H&N FTS, Barracudas, and even Kodiaks, nothing outshoots these until you get into higher powered guns. Other velocity references: Crosman Raven shoots them at 634 fps. Daisy 953 shoots them at 459 fps. Crosman 1377 "American Classic" (new model) shoots them at 542 fps with 10 pumps.

Excellent velocity, accuracy and consistency one would expect from a JSB pellet.

nothing.

These are excellent in weak to mid powered springers. My LP8 loves them. Just be careful of the thin skirts which are common with JSB pellets but if thats the sacrifice I have to make for the best made pellets in the world I'll be careful.

The most accurate pellet I've found so far. 1 hole groups that average .08" (center to center) is the norm at 33 feet with my Beeman R8.

The pellet's diameter is small so it fits into the barrel loose. I assume that the potential velocity is impacted, but the accuracy is still remarkable.

Nothing

Loose fit. Not impressed.

Accuracy, consistency, easy feeding.

A tin with a lid that doesn't need to be fixed on with tap or rubber bands. H&N has the right idea here. That's a nitpick though.

These are the PERFECT pellet for medium and low powered airguns. Out of my Stoeger X20, Daisy 953, Crosman Raven, Crosman 66 Powermaster, and Crosman 1377, they are the most accurate pellet. The X20 is a powerful enough rifle that this should not be the case. But it is! Here's some data. Out of my X20, they yielded 926 fps, for 13.9 ft-lbs. Out of my Raven, they yielded 634 fps, for 6.5 ft-lbs. Out of my Daisy 953, they yielded 459 fps, for 3.4 ft-lbs. My Marauder doesn't like JSB pellets, so I didn't try it, but I bet they would be over 1000 fps with the factory tune. (since regular Exacts yielded 980 fps) Folks, these are worth the money.

The size is very consistent and they fit perfectly in the breach of my NPSS. They are lighter than the regular Exact pellets, and I think that the weight reduction results in thinner skirts. A lot of the skirts on my pellets were bent, but there was no detrimental effect on accuracy. I imagine that the air pressure that is built up upon firing is enough to expand the skirts out to the barrel, and creating an excellent fit. These are, by far, the most accurate pellet in my NPSS. I bought 4 tins, and when I run out, I'll be buying 4 more.

Excellent for a medium power air rifle.

Extremely consistent results with my HW97, one hole at ten meters

NOTHING-why would you

Have found them to be a good value for the consistently accurate results they give.

Quality pellet. No bent or deformed pellets.
