first thing i would do is get rid of the remington shells
Why? Sure some guns may not like a particular Remington loading, but then again .....
My Sako (308Win.) shoots a ragged hole at 50yds., and does about 1" to 1-1/4" at 100yds. with Remington 150gr. Core-Lokts.
My Rem.700LSS Mtn. rifle (270Win.) likes 150gr. Rem. Core-Lokts, and the 100gr. PSP's.
What's even better - they both shoot to the same POI at 100yds. Groups run 1-1/2" to
a little over 1", respectively.
My Ruger 77/22 (22mag.) loves Remington V-Max Premiers - one ragged hole for 9shots.
Am I just lucky? I don't think so. Remington makes some good stuff.
