bronco, I'm really sorry
- You've done all that and still not happy with results.
We disused accuracy of your rifle in that other M70 win thread.
I didn't think my experience would apply to your rifle,
BUT think you should try it now. Don't see where you would have anything to loose.
IME, I have "fixed" the accuracy of 3 very fussy M70 win by a simple change
to a long for caliber flat base bullet.
Since your plan to keep it around for a while, just try that.
