I'm picking up a nice compact 223 this week for sub-250yd varminting and need some help getting together a few different loads to try so I'll have something ready for spring. It has a very heavy 20" tube on a 700 action. I'd like to use something in the 40-50gr range but seriously considering the 52gr A-MAX. I'm using 55gr NBT's in my 22-250 heavy varmint rig, but overkill for carrying all day and shots mainly under 200yd. Any and all suggestions welcome.
