So, I have some 69gr PRVI bullets on the way and will be working up a load for my Norc M4. Given the less than precision nature of the M4, is there any point to doing the usual traverse of loads at 0.2 or 0.3gr intervals?
I am using IMR4895 powder for the first round of testing, my Hornady book gives a max load of 24.9gr and the Hodgdon site gives a max load of 24.8gr. I was planning on simply loading 10 rounds each with charge weights of 24.0gr, 24.5gr and 24.9gr and shooting 2 x 5 shot groups with each one and then picking the best of the bunch.
Is this reasonable or does anyone think I may miss a really great node by using the coarse 0.5gr increment? I should add that I will be mounting a scope for the load development, then running a red dot sight or iron sights afterwards.
