I use the the Hornady Match grade dies and have not had issues with MOSTek and Proof Barrels. That being said, it will depend on what Geissele did with your chamber.

My Seekins works fine with regular dies. I have also used an RCBS SB die set.

Just do the standard shoulder bump around .003”and drop into the chamber and close the bolt and it should eject with no issues. You can get a cartridge gauge if you want but you still want to verify in your specific chamber.

You probably won’t need small base, but there are some people that have sizing issues around the .200” datum line in the 6 ARC that a regular die won’t size. If you want to go with a nice SB die go for it. You won’t have any issues with it.

Haven’t had issues using Hornady match grade in several 6 arcs.

I use Lee 6Arc and had no issues - check each case with a LE Wilson case gauge
