I have 5 barrels for my 2 TC Contender pistols, 22LR, 22 Hornet, 30 Herrett, 357 Herrett and a 357. Having read the thread on twist rates of TC barrels I got mine out to look them over and noticed that the rifling in the 357 Herrett and the 357 are opposite the other barrels. All 5 barrels are TC. I assume that there is a reason for this, can anyone explain why? I recall that an Army range instructor had told me many years ago [50] that the 1911's had a reverse twist to help with the recoil. Any truth to that? Thanks, I enjoy this site and have learned a lot also.
