Winchester Deer Season XP 300 Blackout 150gr X300BLKDS Ammo - Full Auto, Velocity & Gel Test @SGAmmo

[@FiremanFrank24]

That velocity seems great for such a short barrel but it is disappointing that the gel wasn't long enough to retain the bullet. Thanks for posting the test though.

Looks great thanks!

I picked up 10 boxes from you folks to try. Haven't run it yet. My 12" setup needs the giggle function you have going on there! Maybe shoot 2 blocks? I know the stuff isn't cheap and you aren't making much on the ammo; but a review caught in gel would be beneficial. Thanks for what you do!
