RL33 vs N570 (temp sensitivity)

[coyotezapper]

With the 195 Berger and N570 the max will be around 3040 fps at 65K pressure. I would ignore the charge weight and test up to the 3000 fps neighborhood. If you go above 3040 you will be over pressured whether you see pressure signs or not. Velocity=pressure. I have loaded 3 different 28's and I am just about to begin my fourth and they all have tested the same with Retumbo, RL33 and N570. Best accuracy so far has been Retumbo with RL33 giving the best velocity.

I have found my most consistent and accurate load to be around 3030-3050. So I agree that is a nice node to be at. All 20 thou off. This is for a 28 nosler and N570. Last time I shot 79 grains it was 3044-3042-3044 and .3 inches at 100.
