Just got my first Model 14 357.M and the cylinder won't rotate with my reloaded .38 Spl.s the cylinder won,teven close on some rounds. 357M s' with new brass work fine. Well used brass dimensions are all under maximum. Length, width, rim thickness all OK. Loads wont fit a Ruger SP101 also. No problem in a S&W M-10 or a M-19. The DW-14 has racessed chambers as does the Smith M19. The S&W M-10 does not. I cant' think of a reason for this offhand. Any body have a clue?
