I've heard good things about RL7 & H335 for sure in a 30-30, and probably A2520, but I've not used any of these in either of my 30-30's. In my Mod 64 the most accurate load I've ever used was with Sierra 150g Pro Hunters and Leverevolution @ 2400fps. If you're referring to the Pro Hunter bullet, I recommend pushing them fast, they're a little hard, and need extra speed for expansion, based upon several tests I did with them last year. Very accurate!
