I picked up a copy of 13th Edition of Cartridges Of The World, and I stumbled across a wildcat called .22 PDK. It's a 6.8 Rem SPC necked down to .224. The book suggests worthwhile velocities above the .223 Remington. And, I just happen to have a Bushmaster Varminter with a 1:9 twist bbl that I don't particularly like. It's only got 100-150rnds through it.
The designers of the ctg say it has an affinity for 1:9 twists- no info on bbl lengths they used. Supposedly, dies are readily available from somewhere up in one of the Dakotas. No ideas about a reamer.
Is there any reason not to latch onto a reamer, dies, 6.8 faced bolt and convert that rifle over to the new ctg? Is there any reason not to use a new bolt on an old bbl with only 150 rnds max through it?
Anybody see any reason I ought to talk myself out of this?
