Primers

[Carrier]

If there is a different place to post this let me know as I couldn't find where.
Anyways I bought some Federal primers today and just wondering if this is a Ford Chevy thing or not could have got some CCI but decided on these. Is there a difference or just a preference?

There's a very interesting article on primers in the current edition of Handloader magazine (june '15 no. 296. See page 48.

This is a good read here. You will be surprised, but keep in mind this is only one writers results.

Only problem is I can't get it. Download i get will only go to page 10.

Some Difference Some Preference.
Each primer has some differences and the old wifes tale about primers are:
CCI primers are harder and are more difficult to ignite. People that mess with reduced spring weights to improve trigger pull may end up not igniting CCI primers. However said characteristics allow them to withstand more pressure. CCI primers seem to be a little larger in diameter and do not work in some progressive loaders.
Winchester primers are hotter and Winchester allows standard primers in most applications except large cases. The USMC uses Winchester in their .45 ACP Match loads.
In general the magnum primers may spike pressure because of hotter and quicker powder ignition.
I have read that primers do make a difference with some powders/weights in specific applications.

Go to Wally Marts magazine section and read it for free. That's what I use to do, untill the wife would get mad after I said ' Hold on " 6 or 7 times. Then she got me a subcription.

The primers Federal/CCI are made to different sensitivity levels. Lee Precision always recommended CCI as they are a bit harder to set off by accident in the loading press primer attachments or primer tool (or the wack-a-mole loaders) The flip side of that is in really cold weather with a powder that might be a little temp sensitive it will be a little harder to get the same level of consistent ignition.

I seem to recall the difference in sensitivity is reflected in the packaging, the Federals have more packaging space around and between the primers than CCI to withstand the required impact without ignition testing for primer packaging.

Don't use magnum primers so no information on those.

Each manufacturers primers will be a little different. You'll eventually pick a favorite or even a favorite for a certain cal/boolit/weight/powder combination

I wont touch a Federal primer, too easy to set them off. Happened to me twice.

Pick your poison....I use only Federal because once I have the load I want it's a forever load for that gun. Swapping just the primer can in some instances cause a rather large pressure rise so it's easier for me to use one. I will say though I can use Remington large pistol as a direct swap for Federals with no measured rise in pressures.

I've been doing as much research on this as my old brain can hold. So under the Hodgdon reload data for example pretty much all the reloads I looked at call for Winchester primers and a few CCI. So would there really be that much difference by using a Federal instead? I can see a difference using magnum primers instead of regular primers.

Well Carrier....that's the unknown and the reason you're told if you change a component that you need to reduce the load to start with. Somewhere I have a chart from a few years back where just a primer change in certain loads could raise pressures 10k psi or so. Will it happen all the time?....no but it's wise to keep all this in mind. There is a reason for starting loads and it's a good place to start developing any load. Like I say the largest reason I use one brand is so I don't have to test loads all the time. I did that for years but now I prefer mostly the one gun one load method.

Mr James Calhoun has a chart on the 6 br forum that explains some of the difference on primers anyway its a good read for those seeking knowledge of primers. There is another chart with all the pressure ( impact striking pressure of firing pin) against primer to ignite. This chart covers most primers. How ever I cannot remember where it is.

There are differences, however as long as you stay away from max loads and are not working for match ammunition they will all work fine for punching paper.

Thanks M-Tecs I had found a couple of those but the rest is just what I needed.
The old Federal one didn't look like much. The commie ones were worse but some of those others looked like a gunshots in the pictures.

There is a difference in primers makers.But for me it depends on what you use them for.If it is for like stated punch paper or if it is close enough for what you want to use them for then it will not matter much but if you looking for being dead on stick with what your test one where from the start.other wise if you use a differnent one then you did before need to test to see if theres much differnece for you and like stated as long you do not go with the max load also.I do not use mags unless the data calls for it.I stay away from them other wise will need the change your data altogether.
