- or there is no substitute for trigger time. Due to range changes and other factors, it has been a while since I shot at 300 meters with my 45-70 BP rifle. Finally, I was able yesterday to shoot the rifle again at 300, for the 1st time this year... This is my very 1st BP match rifle, a Greener GP martini action with a Ron Snover segmental rifling barrel 1:18 twist. The load is pretty standard, 74grs of 1 1/2Fg Swiss with a card overpowder wad and a 520gr .460 CBE RN GG bullet 16:1 alloy on top of it, my own bullet lube. I shoot this rifle in competition, which means prone, unsupported, with (2-point) sling. I brought 20 rounds for practice, and yes, those 1st 10 rounds were pretty 'humbling' - I was barely able to hold the black at 1st. The next 10 shots became gradually better, I was able to dial in the sights perfectly, up to the point that I was able to put the last 5 shots in the 9 ring - 3 10's, 2 9's. The 9-ring is about 3 MOA, so the load was certainly not to blame. But if I were to go to a match without some prior practice, things would have been pretty sorry. Bottom line? You can do whatever you want in load development, alloy changes, neck tension, primer and powder selection, seating depth, whatever.... But if your shooting isn't at the level where it should be, it serves no useful purpose. That perfect trigger break is the 1st and foremost requirement, and if that isn't present, all the rest doesn't serve anything useful.
