Re: Shortened 6.5mm RSAUM out to 500 yards
Both a 25-06 and the 6.5/284(both at 68grH20 cap) have well over 10gr more capacity than a WSSM case. A 270WSM is 80grH2O cap. A 7RSAUM shows as 72grH2O cap(or equal to a 6.5/284-necked down), so getting it down to 58gr would be interesting. The WSSM has great potential in 6.5, and I just had 2 barrels chambered in an improved version, which gives me 57grH2O cap. Thats as much as can be gotten with it as the brass measures .025 thickness. That extra 12thou thickness reduces it's potential capacity by 5 grains! Neck thickness don't matter-it's full of .264 bullet.
If winchester reduced this thickness, and stopped playing the speed game with rediculous loads and cals, it could have the cartridge of the decade in 6.5wssm. Atleast in my book [img]/ubbthreads/images/graemlins/smile.gif[/img]
If you need drawings, or even want to borrow a full reamer set for it, let me know. If you pursue the 58gr SAUM, let me know. I'm interested in it as well. Like I said, you can buy 300 cases, pick the best, and wear out many barrels with what you have. Regardless of Remingtons future.
