I am a lefty so on the cheep I got a 22-250 with the 26 in bull barrel (the only option for LH ) .I want a 24 in sporter barrel twist is not a concern .A smith told me to get a take off barrel and usually they do not need are do for head space and he could do the swap . Is this likely that the take off would be fine without having to re headspace it ? Opinions please
