Re: Need Advice Glass Bedding a Winchester M70
OP here. The short answer is I'm still working on it. I put in pillars and then bedded the action. I didn't bed anything past the recoil lug. I decided to let the barrel free float. After testing, I was getting some pretty large groups (3"+). As I was getting close to elk season, I reverted back to the original stock. I will probably start working on it again soon. I found some marks on the barrel band that indicated the barrel was touching the wood in places. I don't know if that was due to a failure to completely free float or if vibrations caused it to touch when fired. If I get anything figured out, I will let you know.
I do have a suggestion for you if you decide to bed the barrel band like you mentioned. I suggest you first bed the receiver and get that part good and solid. Fill the barrel band screw hole with modeling clay and tape off appropriately. Instead of using the surgical tubing to clamp things in place, just tighten the receiver screws as normal and let the barrel settle into the bedding naturally. That way you won't be put extra stress on the barrel and receiver when you tighten it later. But that's just my thoughts. If I had the right answers, my project would be done.
And please let me know how that works out for you.
