    It's been successful with some the CF shooters and I read that it lowers pressures. Anyone know of a muzzleloading RIFLE being made with gain twist?

    Talked to a builder today about it and it may have caught his interest.

    Interesting.....……...

    As I understand it, or rather read it, Lothar Walther will make them but it takes a minimum order of 6 barrels.

    Old time long range muzzle loaders , some were made that way. I do know people that shoot them in BPCR .45 and shoot well. If works there it will work in muzzle loader , also helps on recoil. Bartlien Barrel company makes them

    The Gibbs/Metford ML Match Rifle utilized a gain twist along with radius bottom rifling of only 0.003” deep in the 1860’s - later improvements years after Whitworth, Henry and others. Metford and Rigby were tops in the LR game at this point.
    Rigby’s 1:18 is what the Irish Team utilized in the original Creedmoor Match if 1874 vs the Americans.
    Seemed to be a good sales promotion - like many things we see, even today. Like Left Hand twist...
    Here’s a Gibbs/Metford I posted on the LR section under the heading - The Best.

    Ron Smith in Alberta makes them for anything that any one wants. Internationally. I had one built for a 338 Lapua I built a few years ago, It was a tack driver. I have contact info if anybody wants it.

    BPCR shooters use them, you can even get left hand twist if you want, make one heck of good MZ barrel
