Reloading dies for Seekins 7prc

[chrisdixon1]

I just received a Seekins Element in 7prc. I was wondering if anyone has any die recommendations? I will be using adg brass and Berger 175 elite hunters.

My main concern is clickers. Not too sure if clickers are common with Seekins chambers. I have read older posts, but haven’t found any consensus. With the newer boutique (SAC, etc) dies, if those are truly better I would spend the cash. But if they do not help with clickers more than a conventional die, then they may not be worth it for me.

SAC Modular sizing die will work, but the most economical fix for clickers I have found is an Eric Cortina mandrel die. The die sizes the web area even more more than my SAC. And to be clear I think it is nearly impossible to fix clickers on brass that has already started clicking, I would start with the mandrel die and a fresh lot of quality virgin brass.

If you want to fix it permanently have a good gunsmith clean it up with an AW2 reamer, buy a fresh lot of ADG brass, and a standard FL die set, and never worry about it.

Otherwise expensive sizing or collet dies can mitigate the issue.

I myself have a Seekins Element in 7 PRC. Love the gun. I use ADG brass, Forster dies, and fixed the clicker problem myself with an AW reamer. Super easy to do yourself. On a side note, I recommend sending in the Forster dies to have them hone the neck .003-.004” under sized dimensions. This minimizes how much your brass will be worked and I saw my concentricity go to .001” or less for finished rounds after this.

I have the reamer kits I rent out if you decide to do it yourself. A guy who recently rented one from me put together a YouTube tutorial for anyone else who plans on doing it themselves.

I ended up getting the sac modular sizing die. SAC recommended a .306 bushing with their .2815 decapping mandrel. Does this bushing size sound right for use with adg brass? Not seeing anyone use anything that small, most people seem to be using bushings in the .310 range.

Also for seating dies, any realistic difference between hornady match be Forster ultra? Any other seating dies I should be considering?
