I found an excellent load for my CZ75 compact 40 S&W. 165 Rainier bullets Win nickel cases Win small pistol primers 8.0 grains of Blue Dot 1.135 (max) OAL. 5 shot 1" groups @ 25 yds all day long Shooting from sand bags. Don't know the velocity but could tell that the load is a good bit hotter than the Winchester 165 FMJ in the white boxs.  Doug Humbarger NRA Life member Tonkin Gulf Yacht Club 72'73.

Without checking, I would think that you are at the upper end there. I have found that upper end loads are quite uncomfortable in my S&W Shorty Forty and have found lower end loads that are still accurate. I have no need to shoot through engine blocks! Peter.

I got the load here. Taffin Test: The 40 S&W John Taffin Duplicating the factory load of approximately 950 feet per second is quite easy and can be accomplished with 180 grain jacketed hollowpoints and 5.5 grains of AA#2, 5.5 grains of WW231, 7.0 grains of AA#5, 9.0 grains of AA#7, 6.0 grains of Herco, 8.0 grains of Blue Dot, and 7.5 grains of WW540. Loads assembled with 9.0 grains of AA#7 and the Sierra 180 grain jacketed hollow point gave the best accuracy in this bullet weigh. The most accurate jacketed bullet load of more than sixty loads that were tried in the Smith & Wesson Model 4006 .40 S&W turned out to be the 170 grain Nosler jacketed hollow point over 8.0 grains of Blue Dot. At a muzzle velocity of 906 feet per second, this loads groups into one and one-quarter inches at 25 yards. I just substituted the nosler 170s for 165 Rainier bullets. The load is not at all uncomfortable in the CZ compact. Doug Humbarger NRA Life member Tonkin Gulf Yacht Club 72'73. Yankee Station Try to look unimportant. Your enemy might be low on ammo. | |||

Doug, Come back to us on this when you can get around to measuring velocity. It will be interesting to find out what you are getting. In my CZ it seems to me that I get more velocity out of jacketed bullets than copper-coated bullets (Frontier bullets from South Africa). I have posted my results with VihtaVuori N340 for the 155 grain (1,150 fps)and 180 grain jacketed bullets(1,000 fps). Your CZ appears to shoot as accurately as the others. My next drill with a good shooting load would be the "empty two magazines as fast as you can" test, followed by the "constant limp wrist test". The point being to see at what point malfunctions like failure to eject, failure to feed occur or stovepiping, etc occur. I haven't been scientific about it, but in my pistol it seems like I get an occasional malfunction with the copper coated bullets (say one in one hundred) and never with the jacketed bullets. I have no idea why; probably I don't know enough about reloading and am doing something wrong. _________________________________ AR, where the hopeless, hysterical hypochondriacs of history become the nattering nabobs of negativisim. | |||

I've been fooled by the "feeling" that a load is faster than another before, especially with faster powders and higher pressures. It might be hotter without being faster. _________________________________ AR, where the hopeless, hysterical hypochondriacs of history become the nattering nabobs of negativisim. | |||

Thanks Doug. I stand corrected. I need to chrono my accuracy load in the S&W. Peter. Be without fear in the face of your enemies. Be brave and upright, that God may love thee. Speak the truth always, even if it leads to your death. Safeguard the helpless and do no wrong; | |||

I don't have a chrono to check speed.  Doug Humbarger NRA Life member Tonkin Gulf Yacht Club 72'73. Yankee Station Try to look unimportant. Your enemy might be low on ammo. | |||

Doug, I chronographed my accuracy load for the S&W Shorty Forty today. 180 JFP 6.0 grains VV N350 av 934 fps. Just for grins I tried: 180 JHP 6.0 grains VV N350 av.964 fps (not as accurate). Very manageable loads. FWIW, Peter. Be without fear in the face of your enemies. Be brave and upright, that God may love thee. Speak the truth always, even if it leads to your death.
