Dan I'm from swift current. The 37.2gr was 3797 3 shot average with 12fps velocity string. The Hodgon load data says I should be compressed at 36.8gr which I wasn't nor was i compressed at the 37.2gr.This was once fired than full length sized brass so it did have greater volume.Im going to try and go a little higher cause there was no pressure signs but kind of think I will fall out of the node and not be able to get back into it before I hit max pressure. With that kind of accuracy I may just leave it.
That seems pretty good to me. If that sorta accuracy repeats I'd say you have a winner.
Good to see people trying out the new IMR powders. They really brought out the three burn rates most people could utilize for the majority of rifle cartridges.
