I had an upper sitting in my safe that was a 16” 204 Ruger. It shot really well but I was never happy with the velocity I would get. I figured I could get the same velocity out of a 223 and for a lot less money. So I finally ordered a barrel last week. I received it yesterday and took it out to my shop and pulled the old barrel and slapped this new one together. Today I grabbed a mag of ammo from my night rig. I had only planned to get the scope zeroed and shoot a few groups. The ammo I used was some reloads of 50gr vmax and some ramshot. The barrel is a 18” 1-8 twist Wilson arms government profile barrel. I was pretty surprised at how well it shot. Rounds 12-15 for a 5 shot group. This is my 3rd Wilson barrel (not Wilson combat) and they all shoot like this. And they are pretty well priced about $220 shipped.
