Anyone have a chamber or reamer drawing for the 30JR cartridge? I believe it's a variation of the 30BR cartridge. Got an XP-100 built by Kevin Randolph of Texas and the barrel is stamped 30JR and was looking for any and all info. My searches haven't turned up anything useful.

Thanks!

On a BenchRest (http://benchrest.com/archive/index.php/t-52348.html) forum, they claim that it is based on 6.5 Grendel (7.62x39) case.

I don't have a chamber print, but I have owned several of kevin's 30JR's. It's basically a 30BR with a 40 degree shoulder. I simply necked up R-P 7BR brass to 30 caliber and fired them. Really not much difference than a 30BR. Kevin made some beautiful and very accurate XP's.
Post a pic of yours, heck, it may have been one I owned!!

I believe that is called a 30 Major.

My Anschutz mid grip conversion was done by Kevin. Shoots like a house afire!

I also have a Kevin Randolph XP100 in 30JR, I'm in need of a full length sizing die so I can resize 7mm Br. If anyone knows who makes such a die please let me know.By the way the load I was given when I bought mine was 32grn H335 or 30grn H4895 Hornady 150SP great load hits hard at both ends.
