Intriguing.
All reloading rifle primers tested were within about 3000 PSI. So if you are loading a mild cartridge like a .308 Win you can swap out primers without a concern for safety. Whereas a similar report I read a while back with a magnum pistol cartridge (45 colt of 44 mag) said there was a huge difference with pistol primers. Of course always reduce and rework and ware safety equipment. |

Quoted:
Interesting. Would like to see an ANOVA including multiple shooters to see if that variation could be accounted for, but pretty cool nonetheless  Were you talking about doing a DOE with a reloading theme? I remember you speaking about it, but I don't know if you actually had the time to do it. |

Whereas a similar report I read a while back with a magnum pistol cartridge (45 colt of 44 mag) said there was a huge difference with pistol primers. Of course always reduce and rework and ware safety equipment. Actually the NRA conducted pressure tests substituting various primers in .308 using Lake City 1977 Match brass, 168 grain Sierra Match Kings seated to 2.800" and 40.5 grains of IMR-4895. Winchester standard large rifle primers and Federal 210M reached maximum pressure with that load combination. (52,000 c.u.p.) CCI-200's, CCI-250's and Remington 9 1/2's measured 5500 to 6500 c.u.p. lower using the identical components. Commercial cases will allow slightly highe powder charges with this combination of components, never the less caution is needed whenever substitutions take place. Almost certainly a maximum load develpoed using the "softer" primers will be over the top when substituting Winchester 120's or Federal 210M's. |

I remember you speaking about it, but I don't know if you actually had the time to do it. I did indeed, quite a while back. This year has beaten me up in terms of free time. I actually have a DOE set up, I just have to find the time to load it and shoot it.  Even a basic ANOVA can give some pretty excellent results...maybe on one of my days off this week, I'll ask Dryflash if he can resurrect the thread, and I'll put in instructions on how to run an ANOVA. Anyone with a basic spreadsheet can do it.
