so I just bought a crap ton of old once fired 12 gauge paper hulls. About 1000 are Federals which I know about. Most are Western or Winchester Super target (which I assume are the same hull) supposedly from the Grand back in the 60's. Then there are some Remington Shure Shot and Canuck Trap & Grand marked Hulls too.
The questions are...
can I use Federal Paper data for these assuming low pressure?
Do they all take 209 primers or do I need old 109 Remington primers?
I think I have about 7000 total
Thanks
