Sorry if this has already been talked about but I haven't seen anything that relates to my scenario closely.
Im building a 280 ai off a tikka action will have a 22" proof barrel 8 twist and a max coal of 3.5". Want to shoot 155 terminal ascent but that is harder to find than n560 so im more than likely going to chose between a 175 eol and 168 ablr for my go to hunting round. Anyone have experience with this kind of a set up? What powders and velocities are you guys getting? My first custom rifle and first rifle i will be loading for when she is done.
