I have a Marlin 25n (now cataloged as a 925C I think) bolt action .22 rifle. I have been trying to find the ammo it likes best. So far Remmington Thunderbolts seem to shoot best. I have tried CCI Mini Mags (they were the worst) Winchester Powerpoints (not bad, not as good as thunderbolts) Remmington subsonics (always had a flyer) and Federal Champion solids (Very nice shooting, especially the cheap price). Wally world didn't have any match ammo. Just looking for opinions of some good shooting ammo in a micro groove barrel.
