![]() One can only imagine that the big companies went over this with lawyers before they started selling +P+ ammo. If you loaded up some +P+ loads of 7.7 gr, the extra performance would come at the expense of reduced safety margin. The difference of 11.7 gr failure and the 7 gr rating would be a safety margin of 4.7 gr. At 11.7 gr the case fails, causing a secondary failure of some parts in the pistol, and some danger to the tester. ![]() If I work up at 1.169", RP primed brass in a Kel-Tek P11, at 11 gr the primer pierces and the case starts to bulge in the shape of the feed ramp. Some powders like AA#5 have so much power, that they can blow a primer or a case when half full and using a light bullet! No need to compress AA#5.Ģ) The Accurate Arms load for AA#5 and a 115 gr JHP is 7.0 gr 1.095", 4" barrel, WSP, 1192 fps They will bulge cases and bullets before they compress. Some powders like H110 and AA#9 have high bulk modulus. The techinque could compress much more, but I have not done it. This was not practical, just wanted to see what it would take to blow the primer with a 124 gr Hornady FMJ FP at 1.169". 7 gr above where the case started bulging and RP primers pierced.ġ) I have only used "double compression" to increase a 9mm case from 10.5 to 11 gr of Power Pistol. These loads had no where near the safety margin and kaboomed about. Other good loads were 3N37 and 147 gr as well as AA#5 and 115 gr. The flash I have not tried at night, but if it is that bright during the day, it will be bright. Power Pistol is easily the loudest powder tested. On the down side is the flash and report. This means that Power Pistol is not only the fastest tested, but has a very large safety margin in powder and over all length. Hodgdon TiteGroup Pistol Reloading Powder gives top performance for cowboy action shooting, bullseye matches, and IDPA disciplines. With 10.5 gr the primer is ok down to 1.00" OAL. TITEGROUP is a spherical gunpowder that provides flawless ignition with all types of primers and is not effected by powder position in large cases (45 Colt, 357 mag, etc.). More powder can then be added and the real bullet seated on another press. The bullet is then pulled and the powder in the case is then compressed. The Alliant load is 125 gr FMJ 1.150" 6.6 gr, 1235 fps, 34,000 psi.įor the experement, I came up with double compression: a second press with a bullet puller loaded with a 9mm bullet is seated on a full case. What I now carry is Power Pistol and 124 gr. I also have some data from LONG SHOT and AA#7. I worked up until the primer pierced, case blew, or the case was full of powder.
