At the middle charge weight, five of the ten 1 guides had primer flow. Among these was extreme guide circulation, where the firing pin damage had been totally squashed out. The 5 primers had minor circulation in two guides. None of the CCI 500 primers had primer circulation. At the highest possible fee weight, all the guide brands experienced primer flow.


No guides were pierced. The Remington 1 guides are particularly delicate to pressure. They are more subject to primer circulation, and also create even more severe guide flow when stress gets greater than the other primers evaluated. However, they showed no proof of guide flow at the most affordable charge weight, which is a moderate stress load.


If in uncertainty, attempt them with your load to see just how they react. I limit use of the 1 primers in 9mm to reduced pressure loads, to lower the opportunity of primer flow and also primer product connecting the shooting pin hole. I have actually likewise utilized 1 guides with good results in little guide.




January 04, 2011 By Allan Jones By Allan Jones, Most part primers have a little disk of paper in between the anvil and also the priming mix. Yes, those pesky little points we can not do without are difficult to come by at the moment.

Allow's speak about some of the lesser-known truths about guides while we worry about whether we have sufficient. I suspect most visitors know that a guide has greater than one work. Along with giving a stimulate to stir up propellant, it offers a preliminary increase in stress to assist the propellant get to a self-sufficient shed.


United state handloaders have a selection of guide dimension as well as purpose. There are separate versions for rifle as well as pistol; within each category, there are 2 sizes. The very first bit of valuable trivia is that despite the fact that Tiny Rifle and also Small Handgun guide pockets share the exact same depth specification, Huge Rifle as well as Huge Handgun primers do not.


Original situations were formed for Big Pistol primers (primers for sale). Some reloaders chose to switch to Huge Rifle guides to much better deal with the high pressures, and they found the rifle primers stood proud of the case head, an undesirable scenario in a high-recoil revolver cartridge.


Examinations to compare the results of guide substitution have actually been published for many years. I have actually been a lab rat enough time to comprehend that roadway is filled with pockets. We heard a variety of requests to include a primer graph in the Speer manuals I wrote showing what the different primer manufacturers call their primer kinds.

Switching over guide brand names from what we used in the handbook might produce an unsafe condition. One of the last Speer manuals before I took over printed a nice chart of primer sizes and producers' numbers.


As for the "which is hotter/colder" discussion, a similar dilemma exists: primer spec adjustment. CCI revamped its whole guide line in 1989. We bewared to ensure that the brand-new guides can share load data developed with the older versions, but not every change is announced. An additional time, soon after an author pal of mine had a lab shoot a full collection of rifle ammo with the only helpful site distinction being the primers, another primer manufacturer thought of an adjustment that influenced dig this the result of that test.


This was continued over numerous versions of that manual prior to we convinced that company to correct it. People would call CCI and demand that our Benchrest primer was a Magnum because it was printed in this way in another company's manual. Profits: If I publish a primer performance equivalency chart today, it will quickly be obsolete, and some poor sod will certainly attempt replacing primers based on invalid information.


I had to take a different sight, one based on real-world concerns. We checked tons at both maximum normal pressures and also at the beginning lots (some laboratories calculate start lots we fired them). Requirement primers caused no ignition issues at limit tons but posted greater severe variations in pressure as well as velocity in the lower stress routines of the beginning lots.

Showing up at CCI/Speer in 1987, I discovered the genuine story. The steel mugs were neither harder neither softer than any various other brand name. Nevertheless, the very early noncorrosive primer mixes that Dick Speer and Dr. Get the facts Victor Jasitis established had one distinction from several various other guide items at the time the dried pellet was instead fragile.


With little mix under the suggestion of the overseated anvil, a misfire was lurking. I decided the reason I never ever had a problem was that I seated off-press with hand tools that let me really feel the seats. primers for sale. The mix that did not like overseating was retired years prior to I arrived in Lewiston.


You can have too much primer. When the output gas quantity of the primer comes close to that of the cartridge case, often unique handling is required.


It was a traditional situation of high gas quantity however inadequate temperature. The guide's additional gas unseated the bullet while still attempting to light off the major cost, producing one optimal. Then the bullet retarded as it engaged the rifling, creating the 2nd height. Although a shooter would certainly never discover this in a manufacturing gun, that double hump was uneasy, and also we abandoned that mix.
