6.5-300 - 156 bergers

[Nealm66]

Last year I called berger bullets asking for a starting point using n570. They gave me a starting and max load with the max having a 95% case fill. I was surprised and wondering if anyone has used this combo. Burn rate chart has n570 right next to 8133

I've been working with 8133 but not the 156 bergers, using 127 gr LRX I've gone up to 82 grains without pressure and could still keep going.

I’ve been using 8133 with 143’s and 140’s. I was thinking n570 would be very similar and not sure why it has a lower fill

I believe it is denser.
