When buying the action, remember you are building the foundation for a platform. Over the years, your likes and dis likes may change. An Action that will fit a Remington Foot Print will give you a ton of options, so will a savage. Tons of options for Rem foot print, not to mention trigger options.
ON my 223/223 AI switch barrel, I wanted weight so I could see my hits. Heavy laminate stocks help, but ended up ordering a McMillen with the front and butt empty, filled those full of a combo of casting resin and lead shot, added a 30" Max Heavy varmint contour barrel with a muzzle break. This made my Rem 700 weight 19 lbs, and the recoil was so little, I saw the bullets track to the p. dog in high humidity. The 223 AI shoots the 50g V max and blitz kings at 3800 fps with H335 with very long barrel life. I highly recommend the AI, and of course fire forming during shooting p. dogs is the norm. Today, the AI with the 53g V max is fantastic, 12 twists zero freebore to .020 freebore chambers.
Some will boo hoo Savage, but a Savage model 12 with a heavy laminate stock would be a fantastic dog rifle, but I would drill out the butt and fill full of lead.
Bottom like, what kind of budget do you have to work with?
