[QUOTE="Swamplord, post: 1264316, member: 2460"] The 375 Mercenary has the same rim diameter as the CheyTac cartridges and will work on the same actions, my test rifle has been completed today on a Stiller/Ashbury Precision action with a 33" Rock Creek barrel in 8R 7.5 tw at start to 7 tw at muzzle, once the bedding sets up I will be doing load development next week with the 100 pcs of die formed brass I have on hand. the go to action would be the Stiller Tac 408 1.6", Lawton 8500, Barnard P Chey and similar actions that are used for the CheyTac cartridges , case length is 3.1" and perfectly suited for all CT based actions The dies we are making are on 1 1/4" die body blanks as a standard set and 1 1/2" for the RCBS Ammomaster 2 press, which is what I use and prefer with these big cartridges, the 1 1/4" dies can be used in the RCBS Rock Chucker Supreme press since it has a 4" clearance, all you do is remove the conversion bushing and screw the dies directly into press , if the Redding has at least 4" clearance and 1 1/4" die access then it should work, I will be using the Fed 215 Mag primers, I just acquired 5000 pcs a few weeks ago, the powder I will start load development with is 50 BMG since I have 2 jugs of it and it appears to be the most promising powder for the 375 gr and 400 gr CEB MTH bullets, I will also work with the 375 gr and 435 gr Chinchaga bullets, I think they will hold up to the fast tw as they are swaged from .408 cal jackets at .034" thick, As for the brass situation ? .... all on schedule, now that my test rifle is completed, my smith will be making a gauge with that reamer and I will ship it to Bruce Bertram who is expecting it in order to form the 375 Mercenary brass for a 100% match to eliminate any headspace issues , The brass order has tripled in two days and far exceeded my original estimate of what we would need, all a good thing as we will make it in one run and ship at the same time, by request we have extended the deadline for brass orders to February 2nd, (Groundhog Day) so guys can recover finances after the Holiday gift buying marathon, lots of guys want in but need a bit of time , as of this writing there will be at 4 maybe 5 rifles chambered in the 375 Mercenary on the line at KO2M in 2017 [/QUOTE]
