Copper Creek makes ammo, Clay's Cartridge Company, and several others make ammo. Brass from Hornady and I think several of the primo smaller companies. Whidden and RCBS I believe make dies, I use a Whidden seating die and a bushing type sizing die, with Redding bushings. The caliber has pretty well established itself. That and the 25 Creedmoor will definitely be seen a lot more at competition. This build was meant to be a break into comp and varmint rig for those that need/want more of a multi purpose rifle. Some of us cannot afford 5, 6 or 7 rifles, we are lucky to have just 2 or 3...So I hope this gets out there into the right hands...
If your in need of some starter brass, I can get you maybe 100 pieces of Hornady Brass virgin to start playing with.
