Hi M.T. Pockets,
I have nothing against the Magnums, in fact I still have a few boxes of Lapua Factory 300 Win Mag cartridges loaded with the 200 Grn Maga Bullet. I traded the 300WM a Ruger No1 when I did a deal for 3 DWM Boer Mausers including the Special Sporting Rifle or Plezier rifle. I still have an open space for a 30 cal rifle on my licene so to door is still open.
However for a time I will be playing with the 7.92 Mauser and the .303 Improved. I was reading Ackley's Vol 1 and I found a very similar cartridge to my Improved one and Ackley claims that using IMR 4320 with a 180 Grn bullet you can achieve 3030fps with this 303 improved. I find that hard to believe, but Ackley knew what he was doing so......... the trouble is we cannot get IMR powders here but i will play with what I can get and see how it performs. So at the top of the gun related shopping list is a Chronograph

If I can get repsctable velocities and the accuracy to go wiht it i may just try a few of the Speer .303 200grn Grand Slams I picked up years ago. Wish i had found soem more now they might just come in handy, they are only boxed in 50's
