I have an old "N" frame S&W in 357 mag. I have toyed with the idea of having it reamed out to 357 Baine and Davis. The 357 B&D is a 44 mag necked down to 357. This round largely duplicates the 357 Herrett.
My question is would I have the same problem that was inherent with the 357 maximum? Would it eat top straps? Are the cylinder walls on the "N" frame enough thicker than the cylinders on the Blackhawk that the 357 maximum was chambered in, thus putting more air gap between the fire and the top strap? Any thoughts?
