Re: Once Fired Brass
Texas, I would look for pulldown brass. Try Weideners, Bartlett reloading, Pats reloading, and other surplus powder/component supplier.
I bought my brass from Weideners. It was LC69 and I couldn't be happier. You will need to do some work prepping the primer pockets, and necks but it is very tough and accurate. I do not sort the brass and it can shoot sub 1/3 MOA at LR.
For the slight increase in price (costs about 10cents each delvd.), why deal with once fired brass of unknown history. I believe that Bartlett reloading will even do some prep work for a few pennies more per piece.
This is what I use in my hunting rifle and 30 Gibbs.
