K frame .357 and 142 gr rounds

[The grons]

I have heard that 125 gr rounds are too hot for a K frame Taurus model 66 revolver; are 142 gr rounds too hot as well? Someone told me they will crack the forcing cone... I seldom shoot .357 except if I take a customer to the range and he wants to feel the "kick" of a .357, then we will shoot maybe 24 rounds and then the rest .38 specials...

Move up to 158 gr loads, they are a hoot.

Will the 142 gr hurt the gun?

not anymore or any less than any other round. Even the 125gr wound won't hurt the revolver when fired in a moderate amount with factory ammo.. I stongly suspect that where the story about 125gr bullets got started is with hand loads, loaded to the max and used extensivly in one pistol.

I can't see it happening as a general rule.

I thought the taurus 66 .357 was more comparable to a s&w L frame?
I've looked around gun shows but could never find a taurus 66 to handle in person.

142-grain?

Years ago I shot Fiocchi 142-gr. JTC .357s in my S&W M66 and encountered sticky case extraction which I attributed to being loaded a bit "warm." This bullet weight is not going to harm your forcing cone, though - this is associated more with the 125-gr. firebreathers at 1300-1400 fps.
