Looked up some reference data, velocity and pressures appeared quite conservative. So Blindly acquired sixteen#s, and feels like I won the gamble, seems like those that tried using it Consider its a decent powder.

As brass get the job done hardens (up to 4 occasions fired) it requires all the more tension to get a good chamber seal. 15k psi chamber pressure will nonetheless make brass broaden to obtain a excellent seal Regardless how again and again the brass has become fired. With all Having said that, when chamber pressures drops beneath 15k psi, you will not get a fantastic powder burn up and you may not get a superb chamber seal …. both equally causing sooty situations and a thing a lot less than stellar general performance.
The author established all of the primer flash holes were being substantially above sized, Hence raising the pressure. I am not expressing that was the result in in Farmer's illustration. Rather there are several things that can impact tension Other than the powder demand itself. In Farmer's example, it could be many points: as mentioned an about dimensions flash gap, a loose primer pocket, a deep seated bullet (either at loading or from setback), or possibly a variance in bullet body weight, or scenario capability.

A close examine the person granules reveals them to be really irregular in form, denoting They are really from the identical relatives of powders as Hodgdon’s Titegroup. Dimensionally, ninety five p.c of these must pass more info through a screen of .0469 inch. Touted as being a “Winclean” solution in corporation literature, the powder is observed to generally be clean burning, to possess outstanding metering attributes and to include a decoppering agent.

Inside the .40 S&W with its rather smaller situation capacity, I observed the regularity alluded to earlier having an extreme velocity distribute of 1 fps. Groups at 25 yards weren't that modest but have been really acceptable. The bullet used was the Sierra a hundred and eighty-grain hollowpoint.
