Die Lock Rings for Forster COAX

[2011redrider]

Anyone have a COAX and use the RCBS Cowboy die rings?
Need a die ring that will work on both the RCBS Pro 2000 and a COAX if I decide to get the COAX.

I have Hornady rings but they hit the screw head of adjacent dies on the Pro 2000. The RCBS new hex rings are too thin and narrow.

Trying to keep from having to change lock rings when going from one machine to the other.
The Hornady rings measure 1.315-7 and the Cowboy rings measure 1.260. The dies will seat fine on the Pro 2000 with the Cowboy die rings.

Already checked the Forster and Sinclair rings and they are wider than the Hornady.

My coax ring groove dimension measures 1.43" side to side. Actual groove depth is .312". Hope that helps.

Thanks, try ing to see if i can use 1.260-1.270 on Redding or RCBS cowboy die rings on the Coax. Bth of those will clear on my progressive press. Both are about .315 in ht. Waiting on call back from Forster to see if 1.260 is wide enough to snap in on the Coax.
