Seems you and I have both the same Ammos. I know the Federal was a problem, but it seemed I also had a problem with the Remington bulk ammo, but not near as bad. Next time I'm going with CCI Blazer Bulk ammo. Reviews say it's the same as Mini Mag without the jacket, and Mini Mags shoot flawless in all my 10/22, no matter what mag I use, the OE rotary, Steel Lips or Hot Lips. I know not to buy anymore Hot Lips. I've got 2 Steel Lips, 2 Hot Lips, about 8 OE Rotary mags, and I've got 2 BX-25's on the way that I got ordered just before the price went to $80 each IF you can find one now. I got mine for $26 and I got the only 2 the guy had at that price. Then he went up to $79 each.
