[QUOTE="redneckclimbing, post: 1533536, member: 41124"] I like your question. Running some numbers through Quik-Loads, here are some comparisons: 26" barrels on both; 65000 psi on both (That was the default for the 338 Excalibur); 3.750" COAL for both (Again, the Excalibur default) -Excalibur Retumbo at 100.9% full (103. grains) 2748 fps -Edge Retumbo at 107.6% full (93.0 grains) 2730 fps (Side note, I don't know if you could shove that much powder in a case) -Edge H-1000 at 105% full (89.0 grains) 2691 fps -338 Norma Imp.; 3.675 COAL; 65000 psi, 26" barrel Retumbo at 102.1% full (102 grains) 2780 fps! Just a thought, it appears the Norma Improved is the fastest, and shortest, when loaded to the same pressures. Also, Lapua is making Norma brass now, or I'm running Bertram and am really liking it so far. Don't even waste your money on the Norma brand brass, if you are even thinking about any amount of pressure. It is ridiculously soft. On actions, I have built two 338 Normas on Remington 700 Actions now. Seem to be fine. I did have both of them Nitrided along with the bolts. If I had it to do over again, I would use a "cone nosed bolt" from PTG (slightly longer bolt lugs), with the dual ejectors and wouldn't worry about it in the least. Just my two cents, for what it's worth. Also, don't know how far you are shooting but the Hornady 285 ELD-M will get you quite a bit more velocity (+150-200 fps) with only slightly less wind drift, that is what I have switched to. Good Luck, whatever you do. [/QUOTE]
