I mostly use Federal also, Bulk packs and bricks with 50 round box's inside. I tried some Velociraptors but due to it being my first mag ever threw the gun i loaded it wrong and mangled a few, My fault and not the guns.
I just picked up a box of Winchester Hyper X bulk im gonna try as well as some Aguila 1700 fps 30gr hyper velocity stuff thats really hard to find, So i wont shoot to many of those.
I wont even buy Remington .22 ammo, The bullet just flops around and isn't tight in the brass case.
