How much slower speeds, if any, would you expect to get from a 1-9 twist 22-250 as opposed to a 1-14 twist 22-250 with say a 55 - 60 grain pill?

Kirby Allen a well known gunsmith answered that question for someone with info from Dan Lilja's of lilja barrels website.
There is only the slightest amount of velocity loss with a fast twist barrel. Building a rifle thinking you'll get big velocity gains with a slower twist isn't worth it.
In my expierence 1-14's won't shoot 55-60gr bullets as well as 52-53gr bullets. A 1-9 will shoot 55-60 and might be getting iffy on 75-80's. Go 1-9 or 1-8

Thanks, didn't know if the resistance of the faster twist would affect velocity much. I already have the 1-9 barrel. Just have to get the gunsmithing done. Bought one of Montana Rifleman sale barrels for my Win 70 SA which I picked up in a pawn shop for $275 a few years ago. I has a 19" barrel but can't find anything it will shoot anywhere close to MOA.
