Brent is right on the money here. I bored the larger #2 to 11/16" for more all-up weight (match rifle) and the smaller #1 to as large as I could get it for less weight (sporter). I used a 24" Mauser 22LR orphan barrel cut into 2 10" lengths and epoxied in place. Clymer match-dimension chambers in both.
The #2 rifle is almost ridiculously accurate compared to my earlier efforts but it also has several other accuracy-enhancing mods including top ignition, negative headspace, single-side extraction and a new hammer made of unobtainium (grin).
It's mighty ugly (my rifle) but it shoots mighty well.

Later edit: 2 reasons for the short liners, A)only one orphan bbl for 2 projects and B)my whole idea was to severely limit the barrel time of the bullet, to avoid shooter holding technique error on my part.
