Current 6mm Grendel barrel makers: BHW, McGowen and who else?

[SHORT-N-SASSY]

This Discussion on the 6mm caliber brings me back to the 1970's and my experiences with the 6mm Remington cartridge (C.O.L. 2.825"), in Colorado. I used it to good success, shooting a Bullpup'd Remington 40-XB, with the 80-grain bullet, on high country marmots ---


and shooting the Remington Model 660 carbine, with the 100-grain bullet, on Mule Deer.

Here's some downrange ballistics on the 6mm Remington ---

Comparing these downrange values against those of today's 6mm's loaded with all-new high-BC bullets, I think it's fair to state we have a whole new ball game.
