100 Rounds Solid Nylon 50 Cal. Paintballs 50 Cal Rubber Balls Ammo for Tr50 Reusable .50 Caliber Hard Plastic Projectiles for Self Defense

I just started using this ammo in my HDP50 Compact air gun for practice shooting. They work perfectly. I've shot quite a few rounds so far with no misfires from my gun. I have used various other brands where the gun fired but no rounds were ejected. There is one tip I can offer. Make sure the gun is well lubricated. I highly recommend this ammo.

Very well made and perfectly round and sized. Keeps it's shape after shooting so can resize over and over.

Not nylon or solid and clearly have seams Soft rubber and larger than 50 caliber These do NOT fit my gun and again are not solid or nylon The dull ball (left side) is a umarex50 cal rubber The shiny one is the the item i’m reviewing The LAMBID ball is big enough to not even fit into the clip of the airgun so useless

I bought these balls for my Umarex T4E TR50 and they worked out great. They were a tight fit at first and really needed to be jammed in there. After one firing though, they snapped right in no problem. The new clips just need to be "broken in." You also have to make sure they're flush with the clip and not sticking out at all otherwise the clip won't rotate properly. I see a lot of negative reviews by people who just don't know what they're doing... I plan to reorder these on a regular basis. Good quality balls.

Very accurate and tough. These obliterate the X-ring at 20 feet. Light, but excellent for accurate and sustained practice. I’ll continue the purchase these.
