As of right now, I have an older long action mounted in a Choate tactical stock (VERY nice stock by the way) with an EGW base, but no barrel. I am waiting on the paperwork for my 30 caliber suppressor, and looking to set up a long range 30 caliber rifle. 300 Win mag isn't really an option, because it will be pretty hard on the suppressor. Lately there has been some curiosity with people shooting 208 Amax's out of 308's, but not much info on the old 30/06. I'll be ordering a 24 or 26" varmint contour barrel from SinArms pretty soon, but am still unsure on the cartridge. 308 vs. 30/06 has been beat to death, but I'm specifically asking about the 208 A-Max bullets. I got 500 of them from Midway's blemished bullet sale, and am currently using them in a 300 whisper.

My main question is this:

Will I be able to seat the 208 A-Max out to the lands on a 30/06 and still be able to fit them in a staggered feed magwell? I know it wont be a problem if I go with a 308. Any help is appreciated.
