I recently bought a used Winchester model 70 stainless classic in 7mm Rem Mag. I got the rifle for a steal, so I'm thinking about rebarreling it to 416 Ruger. The only problem I see so far is won't feed 416 Ruger as it stands. I have a few cartridges left over from a previous 416 Ruger, and tried them in this rifle. I believe the extra width and less taper of the cartridge is causing it not to hit the feed ramp correctly. I wonder if a different follower would fix the problem? The feed rails are already about as wide as you could go, so I would think they're ok. I want the end result to be a lightweight rifle with a 21 1/4" #4 barrel, and a synthetic stock. 8lbs max. Preferably 7lbs 12oz, or thereabouts. Anyone tried this conversion?
