4895 shines in either although I am sure newer powders work also. I started competition in the mid 60's with a 1903 Springfield but graduated to an M1 when DCM (now CMP) started selling them. I have had three of them. It was fairly easy to bring one of the DCM service grade rifles up to national match standards if you were luckily enough to get one with a new barrel. I had an opportunity to shoot a M14 when I lived in Albuquerque and Navy team was shooting beside me.I am still using National Match brass that they gave me. I did better with them M1.
