I have not gone through all 9 pages. I hunt with a 30/40 Krag, think 303B or 30/303. MGM made the barrel, very accurate and good to 200 yards. Have a 444 Marlin on a Contender and its more then needed for deer or for me to shot. Next there is a 375 JDJ a 444 casing necked down to .375 great cartridge. I noticed a 30/303 project. Consider a 30/40 K barrel from MGM.
