To Marshall, Bill Lester & All...Thank you all for your response..My main reason for the original Post was to see what everyone was doing today vs 25 years ago. Case preparation seems about tha same, but with better bullets.
The most accurate rifle, using cast bullets was a new 1903 A3 Spingfield with a new 2 groove barrel that we lapped out with JR1 (jeweler's rouge 1) crushed in oil. Our favorite bukket was the old Lyman # 308329 - 185 gr spitzer - gas checked, and with one large lube groove. Our lube was pure beewax, graphite, and whale oil ( pretty primative by todays standards) melted, mixed, and poured in a 450 sizer/lube machine. Our bullets were linotype (sized .310"), monotype (sized .310"), and a zinc die casting metal called "Superdie #1 (unsized, out of the mould @ .3105"), all gas checked. We ran the linotype @ 2200'/", the monotype @ 2400'/", and got up to 2700 '/" with the "Superdie", which left a zinc wash that did not build up. We had two quarts of mercury that was "acquired" from NASA and cleaned the lead and zinc wash out with it(we were younger and foolish in those days)
I do have a "M" die that mikes .3075" that I use with jacketed bullets in my single shots. This give a springback on the necks @ .306". I like .002" tight on Jacketed. I have a modified RCBS expander ball that mikes .3095", which gives a springback of .308. This gives me .002" on .310" bullets. I like the "M" and also use one on .357 Magnum and .35 Remington.
The zinc #308329 weighed at 150 grs (linotype @ 185 grs) and had traj. path about like the 153 gr military. When shot in the M1's, had less wash on the operating rod and gass cylinder.
I firmly believe that the #308329 made out of "Superdie", with a meplat that we know today, at 2700'/" would be a good deer, etc. load
Best Regards from The Hammock....James
