Not using N565 but had some decent groups with Magpro and RL22 using 130AB, 129LRX and 140 Sierra TKG. Just getting started in load development at this point. The 140 Sierra has been most accurate so far.
I'm running it in 2 different prc's with Berger 156 EOL's. You need to get some. Below is a load I think is a good baseline with the 156 EOL. Basically, it makes it a flatter shooting 30-06.
With a coal of 3.020", 156 EOL, 57gr N565 is pretty good in a 22" and 24" bbl
With a 140GR bullet, I'd start at 55.5gr and work up to accuracy.
