Last year my old 10" Contender barrel in 357-44 Bain & Davis had the lug break this was an early barrel with a set screw that was in lug to retain bolt . I got nothing but grief from S&W (bought up Thompson including warranties ) so i decided rather then sell my dies to have new barrel made. I ordered a MGM Stainless Steel barrel (27") and a rifle stoke/forearm as my wrist no longer likes a lot of recoil. the barrel arrived within 6 weeks and looks very nice and shoots even better.
My breaking started low and is still 4.9 grains of 2400 under Hornady's book max for a 110 grain bullet . 20 grains of 2400 a Winchester LP primer and a Zero 110 grain flat point bullet is averaging 2300 f/s and will shoot into a ragged hole at 35 yards . My ammo i had loaded for 10" barrel also shoot well and pressures seem mild .
I am quite happy with the barrel and the combination recoil is not bad in a rifle at all!
