So in addition to working these Peregrines in my .300WM, I've also been working with them in my pre-64 M70 in .300H&H. I picked up this rifle a little over a year ago. The original stock was confused by a monkey thinking it was a football and had been ruined in my opinion. The gent I bought it from had a take off stock from Accurate Innovations that fit it, so I bought it too. The blueing was not in great shape either and the rear open sight lost somewhere along the line. But the rifle was a shooter. And I got it for a decent price. I subsequently had it coated and then..........barely touched it. Until lately. I had very little success with the 165gr Peregrines. Velocity was fine, but the accuracy was nothing great.
So I decided to move on to the 180's this weekend and go with a slower powder. Again the N560 as mentioned in my other .300WM thread. And I also worked with H4831. I'm happy to say it looks like the old girl likes the N560 and conversely to the .300WM gives much better velocity to the tune of about 100fps than the H4831 loads with equal or better accuracy.
71gr of Vihta Vouri N560 gave this group at roughly 3010fps. A 71.5gr load gave about 3040fps but the accuracy was not quite as good. Need to repeat this at the range and dial it in, but pretty happy with these results. Velocity was the interesting results here in comparison to my .300WM. With less powder, the velocity was about 200fps higher than the .300WM in same powder. H4831 gives better velocity in the .300WM, but still about 50-60fps slower than this load.
