Way back in the dim dark ages ( before Bad Ass Wallace was out of naps ) English gunmakers used to bore out barrels and fit a replacement rifled sleeve insert . Does anyone still do this or is it just a fond memory from a time when life was less hectic ?

All this talk of barrel reboring has got me thinking about some new toys like a 50 Alaskan on a mod 70 ,maybe even a 470 NE or 500 NE on a Ruger No1. I will get onto sprinter barrels to check on prices etc.

Re-bores are definitely a good way to go if you want to keep the original barrel, markings and sights. And rebores can shoot exceptionally well, too. Two examples in my gunsafe are a Ruger M77 that started life as a .22/250 (22" sporter weight barrel) that was rebored and rechambered to .250 Savage Improved and that gun holds .375" all day long and this is without any bedding or trigger work. I also have a Turkish 1903 that was rebored from the original 8x57 to .35 Whelan (and fitted with a Choate stock and Trijicon Reflex sight) and even though the bore has lots of tool marks (John Bridgeman used to curse the hard steel in these barrels) it still shoots exceptionally well.

the barrel liner has got to be thick enough to hold the pressure I'm told.
