Would you fire form from the 270 case for the 270 Sherman or use the 280 case like you do with you 6.5? Correct me if I am wrong, but I believe that is what I read in another forum you did to make your 6.5 Sherman?

You could use either one but it would be a little easier to use the .280 because of headspacing. You could size the .280 neck down with a .270 die just far enough to chamber stiffly and fire form with some shotgun powder and cream of wheat or neck the .270 up to .280 and then partially back to .270. Another method, which I don't personally prefer, is to simply load a .270 round so that the bullet engages the lands to headspace on and fire away. It is VERY critical when fireforming a wildcat to do it with proper headspacing or you will separate all your cases at the web, if not the first firing, shortly thereafter. Another case you can use, which is a very good option,but spendy, is the 6.5x65 RWS. This brass will last!!..............Rich
p.s. Another good choice is to use Nosler .280A.I. brass. It will require far less stretching and you get a longer neck,

Are there any issues with the C.O.A.L. with the Sherman rounds (6.5 & 270) in factory DBM? I have a Remington (30-06) I am going to do a full custom (6.5) and a Browning (270) that I want to rebarrel (270).

I have plenty of room in my 700 Rem. and cmantha (lrh) has one built on a M70 pre-64 that works just fine.............Rich
