I checked the twist today and was shocked.
I bought a used bench rest rifle in 30 BR and had been playing around with it and it never shot as good as I thought is should. I bought it to shoot cast bullets but it did not even shoot quality jacketed bullet at less than 1/2 moa. I thought it might be a brass problem as I was using brass that came with the rifle that were formed from R-P 300 Savage. I have been working to produce some new brass from Lapua 6.5 x 47 brass and in the process I was cleaning the rifle and decided to measure the twist rate. I was sure it was something like 1-16 or 1-18 and needed light bullets as that was what I would have chosen but the measured twist was 1-10. I was shocked. I am going to try and make this barrel work but that means more recoil than necessary.
