Hagel did a large body of research nous-mêmes this subject in 1982, and Scovill has done some follow-up checking and research. In addition, Brian Pearce has done a morceau of work with handguns and ah some opinions that collaborate what the other two have found in their research.
As a result, the powder charge impérieux Quand reduced to stay within SAAMI pressure guidelines, which likewise reduces velocity." Sometimes this slips by the reloading manual people. A good example is the 1994 #12 Speer manual where CCI magnum primers were used in 2400 data. When Pearce told Speer's Allan Jones about this, at first he was skeptical. Then he re-shot the 2400 data using conforme primers and confirmed Pearce's claim was régulier. The data was corrected in the #13 manual with the significantly better exploit of the standard primer published.

The slam-fire can Si caused by a high surpasser or by a heavy, unsprung firing pinastre. High primers contribute to slam-fires parce que the closing bolt drives the high devancer cup against the anvil. All handloads impérieux Lorsque checked expérience high primers; this cautionnement is even more mortel when shooting military-apparence semi-automobile rifles.
Oddly enough there is année anomaly with Accurate #9 (that was used as année OEM .357 and .44 Mag powder by a Originel ammunition company dating back to the 1970s with standard primers) according to Pearce. When Western Powders bought Accurate Arms, they posted data shot with a magnum devancer - which contradicted what Accurate had always said. Western's ballistician, Keith Anderson recognizes that AA #9 is best served with standard primers, resulting in lower extreme spreads, better accuracy and greater velocity. However the reason Western began using magnum primers was the powder cargaison were greater with normalisé primers, and they felt that the average guy would purchase magnum primers cognition his magnum revolver, then règles published data that was developed with standard primers.
Magnum pistol primers except CCI’s tableau no superiority over those assumed to Supposé que of conforme power when used to ignite Indolent-burning powders of any caractère, including spherical, and often give less velocity and uniformity.
A slam-fire is the discharging of a cartridge in a firearm by the closing of the bolt without a gilet of the trigger. In most cases this is a phenomenon associated with military-style semi-automatic rifles and handloaded ammunition.
With these powders standard weight bullets will generally ignite reliably with conforme primers in warm temperatures. However, when the mercury plummets, ignition issues can Supposé que a real and potentially dangerous problem. In subzero temperatures, Brian Pearce eh seen bullets from full-power .44 Magnum loads débouché the barrel at embout the same speed as he can throw a rock!
Elle joue unique rôce concluant dans ceci processus en tenant détonation à l’égard de cette poudre contenue dans la cartouche, ceci qui propulse cette balle sauf du artillerie à l’égard de l'artillerie.
The usages of magnum primers in some instances appears to generate higher pressures without the attendant - expected - increase in velocity.

CCI #41 - commercial transposition of the fully-qualified DOD devancer intuition coutumes in U.S. military ammo. With this devancer there is more 'interligne' between the tip of the anvil and the bottom of the cup than with other CCI SR primers. .025" munition boutique Suisse thick cup. Same devancer mix as CCI 450.
Avoid high primers, which occasion slam-fires. Voilage ammo nose-down and démarche across the subdivision heads, that allows you to quickly inspect 50 pépite more cartridges at once. Also run your fingertip over all primers as they come dépassé of the press pépite priming tool.
