Tks, Rule303 - I find the larger calibres on the short ctgs. quite interesting concepts. At one time, I chambered a rifle up for the .350 Rem. Mag. necked up to .375 and turned the belts off. I used a .300 Win. Mag. reamer and a .375 neck-throater from Manson Reamers. I still have that barrel around somewhere. I had it on a Styer Straight Pull 8mm action for a while. I was only running 270's at 2,000fps from it - a light load and shooting in to 1 1/2" at 100 meters off the bags - metallic sights, peep/bead.
