[QUOTE="436, post: 282573, member: 16609"] I’ve used a .300 RSAUM for 1k matches since it first came out; it's a great cartridge, way underestimated in the hunting, tactical and target game. With its fat .308 Win dimension case body, it brings all the inherent accuracy of the .308 Win, with the power range of the .300 Win Magnum too the table, in a short, or long action rifle. However’.., I picked the long action with a 1-10 twist 27" inch polygonal barrel. Loading {63.5grs} of H4831SC, Rem 9 1/2 M with a 190gr. Sierra MK; (10) rounds chronograph out at 2844 fps, SD 17 fps, E-spread 58 fps; this was with temp; 64 degrees, Hum 30.38, wind 3 mph’…, a nice day to zero. This load shoots sub 0.5" I could push it harder and “possibly get a reliable” 2900+ fps’…, but it's not needed. When I first built this rifle it was 30 inches in barrel length and I loaded {64.5grs} of H4831SC to get 3000 fps….. But that was a waist with that 190gr. Mk’s, so I cut it back to 27 inches and added a break for practice days. As for your project; I think {.02} if you wanted to use the case volume especially with a 208gr. you might want to look at a long action. It's the case that the advantage is in the cartridge. You’re going to have to seat the bullet deep. And reaching 2900 plus fps with a 208gr in a 26" might be a bit of a stretch. My OAL is 2.90" with the 190gr MK's. To tell you the truth, I don't know want all the fuss is about on short and long action in cartridges like this.... it's kinda like having a 1911 in a Commander or one in a Government... that little barrel difference means nothing in the real world, as too how well they carry, but people just got to have that inch or so off the barrel to feel good. My Long action works great with it, no regrets. 436 [/QUOTE]
