Yuppers too H4350,,, I'm also going to give H4831 a run for its money.
Some powders might be slow ft-per second yet the powders I test have good psi or cup.
Getting the case capacity into the 90 too 97% on up to partly crush has increased down range grouping on paper.
I did the IMR 4064 low ft-per second burn on the weekend as I've found a good charge too launch the 178gr'ers.
I'll choose a fraction slower burn rate powder on the next outting.
