[QUOTE="hammertyme, post: 446645, member: 12863"] I duplicated Rocky Gibbs years ago using rimmed RWS cases for the break opens from Thompson Center. Rocky used a 35 degree shoulder. The first time out everything went just fine with everything above 30 cal. With the 6.5 and 270 calibers. I could never get case life and I noted something wrong with the angle of the shoulder. I checked the reamer and the shoulder was 40 degrees. SO with not getting the velocity I wanted and 3-4 reloads I wasn't happy so changed one reamer to 30 degrees and the other to 35 degrees and my case life problem was solved. The 6.5 X57 mini duplicates the 6.5X284 in all bullet weights. The 6.5 X 280 Rem improved beats the 6.5 X 284 by 200fps in all bullet weights. The RWS cases handle the pressure in the same manner the WSM cases do. The funnel like none restrictive shoulder has allowed me to fill the case and I get some very nice velocities. Right now I am running 2900+ from a 19" handgun barrel and 130 Accubonds. Neal [/QUOTE]
