I think loading 10 different powder loads and 4 seating depths isnt how I would approach finding a load. What powders do you have? Have you tried loading the bullets to the barnes recommended seating depth?
I have tried ramshot hunter 45 gr with over all length of 2.645. got about a 1" group at 100y. I do have a set of loads with imr 4831. I will try those first but from what I have seen the vihtavuori n540 or the imr 4320 will do really good . just looking to split holes at 100y then I will see what goes on at 500y with the top 3 loads. and I have been loading right out of the barens book just no luck with the 243 yet. I did load more with the hunter the book says they did the best with it but with a 24" barrel I have a 22" barrel
