Reloading - Military Brass:

Got a question for all you reloaders out there who reload with military brass.It has often
been said that military brass has less case capacity due to its heavier construction and
resulting case wall thickness compared to some commercial brass.

So having said that,how much variation in weight/case capacity between the two brass
types can be considered significant or relavent to have an affect on chamber pressures and
accuracy ?

For example,I'm trying to reload .223 for my AR-15's.I measured some Canadian IVI
military brass and the weight averaged 100.2 gr. versus an average of 96.2 gr. for the
commercial brass I've tried.The highest powder charge I've tried to date (25.5 gr. W748
w/69 gr. Sierra Matchkings)have shown little pressure signs in either case.This particular
load is not very accurate in my weapon however.

I know that you should allways reduce propellant charges and re-evaluate your loading
when a component change is made but I'm curious as to how much case weight variation is
within normal and acceptable boundries.

Any comments or experiences that anybody can share would as allways,be very much

I use a lot of military brass and I have found that usually backing down one grain is a good
ball park figure to come up with the same loads as you would get with the commercial
cases. I like it because it reloads so many more times than the commercial brass. I try not
to mix brands though and I also like to keep the same lot or at least year stamp if possible.
I like to think it keeps those nasty flyer's out of there(HA)
