Just shoot the factory loads but do this...when you chamber a round, do it gently. Slamming the bolt forward on a round does indeed create a a mall amount of headspace. This will mean that the brass will be thinner above the case head. You may never have this issue, but you might! I have had two 30-06 Ackey Improveds and used (a)COW method, (b) seat out a long bullet in a reload to jam into the rifling to fire and the (c) gently loaded factory rounds if the chamber isn't too big. Just keep an eye on the case heads for any sign of a yellow ring forming. Use any rifle primer, no pistol primers. The thing about using "fillers" is it is "possible" to bulge a chamber using them. Slight chance w/o a bullet in the case, of course, but possible if not balanced out right. On the other hand, if you can get cylindrical brass, just lube well and run into your 30-06 AI FL die until you can close the bolt with just some slight resistance, fireform with any factory equivalent load. Its an easy round to load for, so don't worry too much, have fun!
