Do I need to order some 260 brass?
I have alot of 308, so I had to try.
I can get some 243 free if it will work better.
Actually, the .243 WILL work better. Case oal is 2.045" VS. 2.015" for the .308........... Necking .308 down to 260 yields .044" of movement resulting in thicker neck walls. Necking .243 up to 260 only changes neck dia. by .021" resulting in SLIGHTLY thinner necks. If you've got the cash the Lapua 260 brass is your best bet.
