If in question, attempt them with your tons to see exactly how they react. I limit use the 1 primers in 9mm to reduced stress tons, to minimize the possibility of primer flow and guide product connecting the firing pin hole.

The first little beneficial facts is that also though Tiny Rifle and Small Pistol primer pockets share the same deepness requirements, Large Rifle and Big Handgun primers do not.

008 to 0. 009 inch much less. A variety of handloaders found this out when one of the "mega-magnum" handgun cartridges appeared a few years back. Original situations were created for Large Pistol guides. Some reloaders decided to switch to Large Rifle guides to much better deal with the high pressures, and they found the rifle primers stood pleased with the situation head, an undesirable situation in a high-recoil revolver cartridge.

An additional time, quickly after an author friend of mine had a laboratory fire a total series of rifle ammunition with the only difference being the guides, one more primer manufacturer came up with an adjustment that impacted the outcome of that examination.

Individuals would call CCI and demand i loved this that our Benchrest primer was a Magnum due to the fact that it was published that means in another company's manual. Bottom line: If I publish a primer efficiency equivalency chart today, it will certainly quickly be out-of-date, and some poor sod will try substituting primers based upon invalid information.

I had to take a different view, one based on real-world issues. We tested loads at both maximum normal pressures and at the starting loads (some labs calculate start loads we fired them). Criterion guides triggered no ignition problems at the max tons but posted greater severe variations in pressure and speed in the reduced pressure regimens of the begin tons.

Reaching CCI/Speer in 1987, I found out the genuine story. The steel cups were neither harder neither softer than any type of various other brand article name.
