I think it is an idea that is kind of intriguing in a way.
I have often wondered why not auto cartridges in revolvers ?
I have several styles , both Smith and Colt in the 45acp , I also have 610's and 547's.
But , I know I am the exception , not the rule, my thought about the advantage is the much lower cost of cartridges for those that do not reload, I do , so not a big deal for me.
But, compare the cost of 40 S&W and 357 Mag or especially 41 Mag !!!
Now, I know the 610 will shoot both as 357's will shoot 38 specials so maybe that is the way it should go .
I do not know, I just like revolvers !!
