I purchased a really sweet Huglu/CZ 20 gauge last week, then this week I happen on the section of the forums dealing with building DR's on shotgun actions and boy, the wheels are spinning. For one thing, this is one of the nicest, tightest little shotguns I've ever owned, and I would love - simply LOVE - to have a set of rifle barrels for it. It has a pistol grip and double triggers, which I understand is the one to get as the single trigger is a "double" waiting to happen.

What is the best large caliber that would work on the 20 gauge frame? I am thinking perhaps along the lines of a 400/350 or one of that ilk. I like the idea of 9,3X74R but there are lots of others. Most here seem to have used the 16 or 12 gauge frames, and gone with the largest nitro calibers, but there have to be some good thumpers available in a pressure range suitable for this smaller frame.

Also, I got a very interesting brochure from Gordon Harms, who is a gunsmith apparently undertaking to build DR's on shotgun frames, and his work looks pretty intriguing. He's had good success so far. Do any forum members have any acquaintance with him or his work?

One last thing - if you have the single trigger action, is there a way to make it safe for heavy DR use, or should you just avoid the single trigger altogether?

Thanks for any advice.
