My 15-22 has been flawless with all the ammo I've tried in it. Federal bulk is mostly what my son and I shoot out of it. As far as loading the mags wrong if my 7 yr old can do it with no problems I certainly hope an adult can.
Give the CCI Tactical a shot, I love this ammo to death. Some highlites:
1. Copper plated (less lead buildup in the barrel)
2. Bullet is set tight in the brass casing (not all manufacturers are)..Pressures are consistant vs erratic.
3. Clean burning powder and solid primer performance, ( 99.999% fires) zero FTF and FTE in my M&P..
4. Light wax coated during package (bulk of 375), helps lubricates for FTF from the mag to breach..
5. 1200fps, less from CCI Bulk at 1235, reason, cycles better in semi-automatic's..
6. Accurate with zero flyers, (Winchester with loose bullets flew like a shotgun blast, I could never understand why)..
Granted it is a little more expensive but the performance is tops.
Mine does not shoot Federal very well at all either, but mine LOVES Blazer and CCI. All i stock up on is CCI Blazer ammo and CCI Tactical. I am about to put an SSAR-15 stock on my 15-22 and hope to god it still likes both those 2.
Just proves the statement that many of us have been making: each firearm is a law unto itself as to ammo preference(s). There are no hard and fast rules.
i use CCI SV and love it....yet to have a failure, had 4-5 out of a box of federal...which I was happy with but had a few flyers.
