Anyone bumping the 6.5 PRC to 7mm?

[4xforfun]

The title says it all. The .532 body instead of the .552 of the 7SAUM would be nice.

Anyone? I see a thread about 7 months ago that didn't go anywhere.

Or the Thread I just started a couple days ago. .338 RCM is the same only smaller Caliber. Roughly 69 Grains Capacity, similiar to the 280 Ackley Improved. I made some from 68S brass, .520" vs .530" just to see how they looked. I use the Neck - Shoulder location of the 7-SAUM because I don't have a 6.5 PRC die set. This Cartridge needs a 35-40 Degree shoulder, due to poor quality Brass from Hornady. Optimum Dimensions would Duplicate the .300-RCM Shoulder Location with at least 35 Degree Shoulder To match Neck location of the 7-SAUM. This would afford Roughly 73 Grains Capacity. This could Rival the 7 Rem Mag performance,,, - at TRIPLE the Cost. IMO / Edited to remove any confusion regarding Loads or Powder.

Curious why you are necking up the 6.5 PRC instead of necking down the 300 RCM, just curious? That said I have a reamer for the 7mm/300 RCM but have not chambered anything yet but plan to sometime yet this winter. Basic difference between the two is that the RCM is about 1/10" longer than the PRC, slightly more case capacity.
