Another satisfied .40 hp owner, blued with adj sites. Recoil spring is heavy enough to drive bullets deeper into rem brass. Am now using Lee's undersize die to reload for it. A little picky about loads and bullets for best accuracy, but 6.8 grains unique, Rainer 155 gn flatpoint, Fed 100 primer at 1.119 col is quite accurate. Bout 1150 fps from BHP.

With new brass, am using 7.0 grains unique with Hdy 155 xtp at 1.124 col or Speer 155 gd at 1.119 col. Very accurate in BHP (bout 1190-1200 fps) and S&W 646.
