Moron me, Jesse, I didn't realize you had a Savage but were just griping it. Don't be ashamed about impeccable engineering taste. (Except that rear pillar/sear thing, and EVERYONE sells lawyer triggers these days that stink.)
I got a 223 barrel from Sharp, four week turnaround, I got the short throat and tiny chamber I wanted in a 1-8. I wasn't sure about the twist, but it worked out outrageous.
I didn't get an Ack because I have a BR.
I have two one-holer loads already, one for gophers using the Sierra 40 HP (cheap is good) and one with VM55s, the latter was the best load in my old barrel, too. And I haven't done anything resembling real load development. I am just in shock at what a death ray I have now...and the original barrel was no slouch, either.
So I would recommend you order a pipe from Sharp Shooter. End of story. If you wind up hating Improveds, you can always unscrew the thing.
