I've shot quite a bit of the Federal 38G load in several guns. It has been very accurate, with mild or no leading. No bullet pull problems.
These were all in the silver box.
Bullet hardness seems to be between Winchester and the softer Remington. I quit buying Remington ammo, though, due to quality control issues.
The 38G penetrates well, although expansion may be less than some modern 125-135 grain JHP rounds. If you have to shoot a heavy person or a big dog, that penetration is a good thing.
I want to try Buffalo Bore, and their hotter lead HP might be a great load for K-frame .357's. The cost has stopped me so far, but when I get a little ahead, I may try some.
