Thanks to all you fellows, I thought maybe I was reading COTW incorrectly. I checked the 9th edition (latest I have) and it still lists the 150 grain or 173 grain bullets with 50 grains of IMR4895. In fact the 173 grain load is listed as the National Match load @ 54,000 psi. The 150 grain load (M2 ball)is also listed with 50 grains of IMR 4895 @ 50,000 psi. I guess I will back off a bit and work up a load that shoots accurately in my M1. I had always been warned to stay away from IMR 4350 because the pressure was still too high when the bullet passed the port, leading to bent operating rods. If the military goes with powder of 4895 burning rate, I guess they must have had a reason.
Thanks again.
