I have a 1905 Mk ll***, one of the ones sent to the U.S., and would like to work up some loads for it. I have seen some references in old posts that the bore on these is smaller than .311 and someone referred to them as a "tight .30 ". I have both .308 and .311 jacketed bullets ( both 180 gr.) and gas checked cast in 187 gr .312 and 180 gr. .309 on hand and have IMR 3031,4064, 4895 and Red Dot powder. Can anyone clear up the bore size for me and does anyone have a pet load based on the bullets and powder I have on hand?
thanks
