I would like to hear from anyone that may have determined how much of an influence a small variation in bullet weight affects accuracy.
I just finished sorting by weight 500 SMK 30 cal in 175 gr.
I did not count how many were actually in aech weight group but this is what I found.
1/3 of total were 174.9 gr
1/3 of total were 175.0 gr
about 1/6 of total were 175.1 gr
about 1/6 of total were 175.2 gr
a handful were 174.8 and 175.3
Some may think that I am just wasting my time. I only shoot 100 yards at this time and all these may be adequate for reasonable accuracy.
I have annealed, sorted brass by brand, weight, and dry capacity as well as sizing to the same dimension and trimming to the same length.
My shooting at 100 yards is just a starting point if I can get a real accurate load and I can do my part.
I have access to 200 and 300 yd ranges.
I am trying to take all variables out of the equation so that I can see the results of my own shooting ability.
Does 0.1 or 0.2 gr variance in a projectile that weighs 175 grains really make a difference at the distances I shoot? At what distance does it make a difference?
I usually group 1 inch at 100 yards from a Rock River LAR 8 with a 26" bull barrel.
