I have a test-fired only Proof carbon fiber 6mm SAUM barrel for a Zermatt Origin action for sale. This was chambered up by Circle W Guns. Specs as below.
6mm SAUM Proof carbon fiber Sendero contour
1-7.5 twist
20" finish length
Threaded 5/8x24
Throated for 115's at short action mag length
Initial test firing by gunsmith with N565 as below with 115 Bergers. Ten shots with left shot at 52.5 grains up to 58 grains which is the high shot. The remaining 8 shots were between the 52.5 grain load and 58 grain load. Looks like a very wide accuracy node. N570 would likely be a better powder choice for velocity, but you can see the accuracy potential.
I do have some new ADG 7mm SAUM brass that could be worked into the deal for extra. This is a neck down only with no neck turning required. 7mm SAUM or 300 SAUM dies with bushing would work just fine, so no custom dies required.
I haven't shot the barrel. I have too many projects going on right now, so I'm going to let it go. I would take $1100 shipped for it.
