I have been down this road 4 times (4 kids) Trying to find the perfect setup. I own a ruger go wild with a 16.5 barrel in 6.5 creedmoor. It’s not a bad gun. The scope height and eye relief is gonna be the problem. Too close and they get busted by the scope. I messed around with 300 blackout on a AR platform and it was effective just limited range. The 243 seems to be the best option for
Us. Everything shot has died quickly.
