Pros
Very good velocity and accurracy shooting from my .25 Air Venturi Avenger. These heavy pellets make a good sounding thump on game.

Cons
Costly like eveything else in these times.

Every rifle and barrell is different so various projectiles have to be tried until you find that perfect match.

Pros
Having tried many pellets through both my FX rifles 'wildcat mk3bt .25 and typhoon .22. Both favour the exact king heavies. I had them reccomended to me by another rifleman. Of course I had to try other brands and styles but none of the others gave the consistant accuracy I demand.

Cons
Would be better if they were in 500 per tin and cheaper..lol

I shoot hole in hole groups with this pellet. It could be the gun. But. I do know that the pellets are excellent.

Pros
These shoot well out of my Gen 1 Umarex Guantlet .25 cal. I would not spend a lot of money trying to find a pellet that does. If you watch reviews on the gun. These work well with it.

Cons
I don't have a con.

Pros
Seem to shoot better than regular 33.95G. But put calipers on both and didn't see any difference.

Cons
Bought two 300 count tins of MK11 after a Long wait. They were just wrapped in paper and thrown in a box. 1 tin severely damaged. Went through all pellets 15% unshootable. Another 12% damaged enough for bad Flyers. Not acceptable for me.I won't be buying anymore pellets from airgundepot until they learn how to protect the delicate tins and pellets. It's like they came from a Ebay seller and not a big airgun company.

Pros

Cons

You need to be shooting a high powered PCP to get the best out of them.

Pros
On point, these things shoot very well out of my SLK 19, 25 cal that's all I shoot.

Cons
nothing

I’m a first time buyer. I was really nervous about what kind of condition they would arrive in. This place also has the best price on them as well. When I got them(which it took them a while to actually ship them, but once they were in the mail I got them fast.) they were all in great shape. I didn’t see any of them in a messed up shape. Fit well in my gauntlet mag. Getting my hand pump Wednesday so I’ll be layin them down range before to long.

Pros
Great shape out of the box. Heavy little suckers.

Cons
None.

I own the Hatsan bt65.25 and wondering which of the jsbs people prefer more. The 25.39 or the 33.95. I did tune the hammer spring and my air superiority regulater is on the way. Have only had a chance to shoot the 25.39s and am chronying over 1000 fps two clips & just under a 1000 3rd clip. Any suggestions or is it just something I'll have to see which ones my gun prefers?
