Thanks Airgundepot for replacing them free of charge. I've done business with Airgundepot for many years and they are the best! They are very knowledgeable of the products they sell and if you have any problems they will help resolve them fast. Thanks Airgundepot.

JSB is the best pellets I have ever shot.

This tin was about half deformed beyond shooting.

These pellets are great for long distance shooting out of my Umarex Gauntlet 177 cal. I can hold a 1" group at 50 yards.

Very good quality pellet

Accurate and great for paper

A little light for hunting anything larger than grey squirrels.

I've poked around trying to find the right pellet for my Gamo and this is it. It's a baseline rifle but is accurate and reasonably powerful at 1250 fps. At ranges of 25-40 yards this pellet is laser accurate. Zero'd at 35 yards and they are consistent and hit with a big "whack". Squirrels do not like this pellet.

Heavy but flies straight

Off of another user's review of the Hatsan AT44W-10 QE Rifle of this being the best pellet for it I purchased a tin of these JSBs with my Hatsan AT44W-10 QE. The person was correct that these JSBs were great pellets with that rifle. I started using these in other airguns and found out that these work great in other airguns I own. Considering the weight of these pellets I figured these would only be for Magnum or PCP guns but I was wrong. These are the best pellets in my CO2 Beeman QB78s and QB79 rifles. What I was shocked with these pellets were the best for the low powered Beeman P17 pistol!

Uniform and consistent quality.

Let us know if you have an order already in or place an order and we can get these pellets out to you. Sincerely, Airgun Depot Customer Care Team

I have a Ruger Airhwok Rifle and it seems not to be very accurate. At 25 yards, it hits allover the target but never a 1" pattern. I have tried six different brands of pellets and I can not seem to find one that will work properly. I guess I have bad luck, since this is my second rifle and I still can't get it working properly. That's why I'm looking for a good pellet, one that will make me enjoy my shooting.

asked Joseluis Curiel

The reason you have not found an accurate pellet is because you have a spring powered air gun. Most spring powered air guns are hold sensitive which means they will shoot differently depending on how you hold them. You always shoot a spring powered air gun with the artillery hold. You hold the gun loosely and let it recoil. This pellet is very good and I get 1/2" groups at 30 yards with a RWS 850.
