Copied from Dr. Mikes post. Worked up to 49.0 gr. W760 for 2800 FPS in a Winchester M70 with the 140 gr. Ballistic tip. At 49.5 gr. bolt lift stated to feel sticky. Load was fine in a Ruger #1A but locked up the bolt in my FN 98 custom Mauser. The Mauser seem to show high pressure long before the other two rifles.
Loaded up a load with the 175 gr. Hornady round nose just for grins and shot them in all three rifles. The M70 and Ruger showed velocity in the low 2300 FPS range. The Mauser ran about 130 FPS faster with the same load.
FWIW, that Mauser is very accurate with the 175 gr. Hornady's and with the 170 gr. Sierra round nose as well. Excellent accuracy with Winchester's 145 gr. Power Point. I'll lick that pressure problem yet as I want to hunt that rifle.

No Ramshot Big Game? That's what I use with 140s in my 7mm-08.

But Scot-man...you still haven't told me what "amount of R17" and what primer you use for the 140AB & 175PT!? ha I understand ....I have a Marine SIL; so yes, I "know" I'm a Doggie Redleg, but I'm still "your elder"...lol Hey I know you're busy, I took a pt time job in the freight dept of Home Depot...I'm kinda dragging myself...
Well, I am away from my load book right now Jim, but I will say I use Norma brass, CCI BR2 Primers, and I would guess, if you held me down, about 50'ish grains of RL17 for the 140 AccuBond. If I get around my QL I will run you some digits to get you started.
