Ammo for a Henry Big Boy Steel

[peanut27]

I recently bought a a Henry Big Boy Steel in .38 cal and I am wondering what ammo you have used? Henry's literature says that if you are shooting 38 special like I am that they must be 158 grain as lighter bullets will be too short for reliable feeding. My first couple of boxes were Magtech FMC-FLAT (38P) and so long as the lever was operated "crisply" there were no feeding issues at all.

Has anyone had any experience with Magtech lead round nose?

Has anyone had any experience with Magtech lead cowboy action?

or any other brand of ammo in lead round nose.

Thanks
Francis
