I am back from my second range test. The cases used were fire-formed and had 2g H2O increased case capacity.
Load was increased from 55g to 57g IMR 4895. And, velocity increased from 2932 fps to 2970 fps.
This already exceeds the published max velocity of the 300 Win Mag with the same bullet and same powder.
No signs of excessive pressure and easy extraction. Next outing will be increased to 59g.
I am really starting to like this rifle ... a lot.

Hello all. I finally had a chance to take the action out of the stock... the action was stamped ... FN - made in BELGIUM ... I also found a stamp on the barrel .. R.M.OSBAHR ... the date ... 08 16 60 ... and CARMICHAEL'S ... (while searching the internet I found a M1-Garrand with a barrel that had a similar stamp and a 1955 date) ... I also found the M-2 Canjar Match Trigger and that the action was glass bedded. No wonder its such a good shooter.
