Hi all
Ive been loading some Hornady interlock 150gn sp (flat base) for 308, using Norma cases and Cci br2 primers. Currently seated at 2.740" col, I've got up to 48gn of n140 without showing any signs of pressure . However in a 20" barrel I'm only seeing about 2540 ft/ps over the chronograph.
I'm concerned to go any higher with the powder and was wondering what the experiences and thougts/ observations were of anyone else using this combination of components.
