Rechambering the 30-30 Win. to the 30-30 Ackley Improved is done on a daily occurance. Depending on barrel length, you can gain from 100 to 250 fps. in velocity. In guns like the T/C Contender, with the improved case design having minimal body taper, it reduces the backthrust that is transmitted against the breech face. In the N.E.F. single shot rifles, I have a lot of guys using the 30-30 Ackley Improved as an easy carrylight weight varmint rifle and they are shooting the Hornady 110 gr. V-MAX to 3,000 fps. with amazing accuracy....
