Locking Rings for Dies

3348 Views 13 Replies 10 Participants Last post by  unclenick
I just recently bought a new set of dies from RCBS and the locking ring is not the same size as it use to be. I am using them in an old Bonanza (Forester) press. The locking ring on the new dies is only about 1/4" thick. The rings I need are at least 5/16". There is just so much play in them it is impossible to get the same results in every case.

Are there new rings available anymore for the older equipment???

Forster, Hornady, original RCBS, Lyman aftermarket, and Sinclair lock rings are all cross-bolt style and will work fine in the co-ax. RCBS switched to set screws (steel first, then brass) at some point a long time ago. Lyman includes set screw rings with their dies, but sells the cross-bolt ring separately.

These cross-bolt lock rings lock securely and squarely on the die body, without marring the die threads, and are thicker than set screw types, which works well with the co-ax.
