Gentlemen,
I know I've read a few times, over the years, that it is not wise to shoot full power 357Mag 110g and 125g bullets through a S&W K frame revolver. Is this a real issue?
Also, is this true with 38sp +p ammo?

I've seen some photos of cracked barrels at the flat section of the barrel right in front of the cylinder and they said it was caused by light weight bullets.
I've got one box of 357 110g and two boxes of 125g. If I stretch my shooting of these over time,( a cylinder every so often) would it be a problem?
I did a search but it was fruitless.
Please give me your thoughts or experience with this issue.
Thanks guys.
