Re: Reloading - Looking After The Brass Cartridge Case By Matthew Cameron
I have to respectfully disagree with davewilson's comment re weighing brass. For years I never
weighed my brass and just accepted the accuracy, or lack of, more the fault of the rifle than the
shooter. Along with 75 to 100+ fps variances of my reloads.
I've been weighing cases now about five years and there is difinitely a difference! It is not
uncommon for 8 (lowest so far) to twenty fps extreme velocity spreads while chronographing.
A couple days ago I was chronographing my load in 9,3x62, and produced 11 fps velocity
spread for six cartridges. I sort cases within 1.0 gr variance, and adjust my reloads accordingly.
Whether hunting or target shooting, reloading ammunition is all about consistency to me. The
more consistency generally produces greater accuracy. I want the most accuracy I can obtain
from my rifle, ammunition, and myself, that I'm capable of producing. I've also found it worthy
of weighing Lapua, Hornaday, Norma, and Nosler brass as there is often a five grain difference
within any lot.
A disregard to case volume capacity is a foolish proposition, and anyone suggesting otherwise
is courting a potential disaster.
To me it's the difference between "acceptable" gun writer accuracy (1 1/2" to 2"), and sub-MOA.
The longer the distance one shoots, the more accurate we need to be. YMMV.
