Tested 870gr hard slug with 7383 in 3" plastic. Over 1500 fps in NEF short barrel. I wish it had a longer 32" barrel.......... The folks at 50 Cal suggested we write up a piece on the 12GA FH. Interested in what we did to make hairy cartridge using 50 cal brass adapted to the 12 gauge shotgun platform. A job for Rob to do? His wild idea has been viewed about 400,000 times in the forums we put it in.Ed
