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.

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.

The skirts are much thicker which makes them less prone to being bent up as much

Pros
I have using the 25.39 in both my MkI and my new MkII with the new power plenum. Then I decided to step it up a bit by getting the JSB MK II Heavies. Wow do these hit extremely hard! I took advantage of a great Deal and purchased 32 tins at one time. These are just as accurate as the 25.39's at 50 yards. But at 100 yards and Beyond they are doing great at 1" MOA @ 100 Yds. the sound of the impact when hitting an animal or an object has a very nice "SMACK" to it I appreciate the sales team making this huge purchase more financially possible by giving a Military Discount. Be sure to ask for Ruth when placing your order, She is extremely knowledgeable and helpful with any questions that you ask her.

Cons
The biggest thing is you take a hit of loosing 50 Rounds per tin as the Qty is 300 rounds rather than 350 per tin (The JSB 25.39's) Which in turn make a tin of Heavies more expensive due to the fact that your loosing 50 rounds per tin. ( I am sure that you get my point by now) Also I was told that the new tins were suppose to have a twist off lid now, That is not the case......At least not with the 32 tins that I received. It would be much easier to buy in bulk if the price was lower. After all it is just lead.......maybe offer a 500 ct tin for the same price as the 350 ct tin? Maybe you don't need such an extreme profit margin? Then also you would be getting more sales as apposed to your competition? Just a though

Perfect match for my Airforce Condor when taking out pests.

Pros
No need to buy any other pellet for my Airforce Condor. Once dialed in the quality of the gun allow me to shoot fantastic groups. Squirrels and chipmunks never take a second shot from these pellets.

Cons
no cons

Equipment used: Taipan Veteran .25 & range finder: Mounted scope, zeroed in three shots @ 30 yds. Took additional shots out to 50 yds, gun was on. Pellets performed as advertised. Eliminated two pests 30 and 41 yards. Very happy with the performance of the new pellets. Shout out to Airgun Depot for the fast shipping of the above item plus two others and response to my e-mail. Very pleased with their service.

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?
