H110/296 problems?

[N310toN170]

The recommendation is that reduced loads less than the minimum not be used. I have yet to ever see a factory load for 300/221. The primary concern is case capacity. With a NBT 125 loaded to 2.085" and 16gn, according to QL you should be at >85% case capacity.

When you start to workup sub-sonic rounds, using <50% case capacity starts to greatly increase the potential for SEE.
