Confused on ammo

[Rob454]

Ok so I got a model 19-7 357 magnum. I started reading and some articles state not to use 125 grain loads because it will crack the forcing cone? But you can shoot 158 grain loads. So I bought some 38 ammo and some is 125 grain and other is 130 grain. so does this mean I cannot shoot this 125 grain ammo out of my 357? Then i read that if the forcing cone cracks you basically got a parts gun cause there are no more model 19 barrels. So if that happens is there another barrel that can be used from a different model gun or can one be adapted to the model 19?

The validity of this claim is somewhat in dispute. The model 19 was the first K-frame chambered for .357, and there were reports that extensive use with light bullets (I heard this about 110-grains) AND hot loads could cause premature wear on the forcing cone as well as excessive flame cutting. I've heard from some pretty authoritative sources that this is bunk, but evidently Smith put enough stock in the claim to create the L-frame.

It's probably a YMMV issue. I avoid these loads in my pre-19, mostly because it's a collectible gun in very good shape, and I have a 686 to shoot heavier loads in. I think you'd have to do a lot of shooting with these loads to see the problem, though.

Also, the concern was with .357 Magnum ammo, not .38 Special. Shoot all the light weight .38 you can find.

Oops...I should have mentioned that, too. Good catch.
