I shoot CCI mini mags in solids because they are the most accurate threw my rifle in a non target load. Federal Gold Medal is the most accurate but gaining 1/8 of an inch is not a biggie considering no shots are taken beyond 50 yards.
Personally I've never had any problem with bulk packs of Federal but have experience pleny of problems with most Remington and Winchester 22lr with the exception of the Super X. Poor accuracy ,feeding problems , squib loads to the point I have to unload and check to see if there's a barrel obstruction.
