JD's post got me to thinking and it occurred to me that I had tried Speer BT 165's in my M70 with RL16 and had walked away from it because it didn't shoot up to standards for this gun with a couple loads I thought should be close.
Not horrible but both 150's and 180's of numerous brands were not hard to get to shoot very well out of this gun so I moved on from these 165's and forgot about it.
His post spurred me to keep it simple and try 2 things I know. This rifle generally likes around .040 off with numerous bullets, and IMR 4350 likes a full case.
It already shoots several bullet types of 180 gr with 56.2-56.5 gr's of IMR 4350 without pressure, so there was no need to use starting loads going with a lighter bullet.
Just loaded up 1 at 56, 1 at 56.5 checking pressure just to be safe, then 3 at 57gr's.
5/8" MOA out of the box with no load workup which is far more typical of groups with this rifle.
The old 1969 M70 complete with see thru mounts and a heavy cross haired Simmons 3x9. This rifle routinely dispels 2 myths. A. Early post 64, M70's aren't good rifles. B. 30-06's can't hang with 308's for accuracy.
