Bipod and sandbag on the bench. My tree stands have wrap around square tube rests that work well with foam water pipe insulation taped on. Lots of striker shooters like the big calibers, I switched my .243 to a .221fb. Changed the bolt head and it can switch to .300 blkout or 6mm X 45, both work for deer in NC. I don't care for heavy recoil.

Snowgetter suggested Specialty Pistol site, that is a good one.
