Recently bought winchester low wall with dies and brass. Would appreciate any reloading data that anyone would share. Just plinking so not after anyone's competition secrets.
Thanks

15 gr. of IMR8208 behind an 85/87 gr. bullet.
Safe start is 12 gr. and work up. {Follow this not top-out}
That powder seems a little slow for the case, but's it's just ahead of the 4895 powders of various makers with a lot more safety ceiling.

SAFE START LOAD TO WORK UP FROM IS 12 gr.

For 75 gr. pills I like AA2015. I topped out at 14.5. Start is again @ 12 gr.

Work up in increments.

I'd look for some new made brass if yours look old. The SS dates back to mercury primers and black powder both of which is hard on cases.

Minimum sizing (if the chamber will let you) and expanding the case mouth along with annealing will help with case life .

Thanks to both of you. Good info. The brass is Jameson and looks new.
