For shooting paper I pretty much stick with Berger. With your 9 twist you can go as heavy as the 73gn HPBT target bullets. Their target bullets do measurably better for me than their varmint bullets, wish they would make their 64gn in the target variety. Sierra would be my second choice. I also like the Hornady V-max, not quite as accurate but cheap

My 9twist with the Sierra 69gn Matchking and H335 did best at 25.2gn powder, Rem 7 1/2 BR primers, Lake City Brass, Chrono at 3100fps. Your mileage will vary.

If you really want to work up an accurate load you might want to do some ladder tests and then play with your seating depth though your magazine will limit how much you can do there.
