Default Mixing Primers

I usually use CCI but found some Winchester so I bought it. Should I keep the Winchester apart from my CCI so I know what it was loaded with? I generally just dump the primed cases in a bin waiting to be loaded.

I also have 3000 CCI Magnum Small Rifle Primers Just grabbed them by mistake. I learned here they can be used with ARís. Should I separate those? I figure separating Winchester and CCI probably not a big deal but the magnums maybe should. Gonna be a while until I get to them anyway. I have 3000 of the regular CCI.

Depends on what youíre loading and what for.

If for bench rest shooting or maximum loads: separate them.

If itís just range ammo, I wouldnít be too concerned.

I use different brands of primers, depending on what’s available locally. I keep them apart and track them separately, even if the only difference in the load are only the primers. I’m looking for load performance, accuracy and safety. Primers can affect those parameters.

Just paper punching range ammo.

I prefer consistency, accuracy and ballistic uniformity in my reloads. I've often found 2 MOA or more difference in accuracy and a 100 fps spread in velocity between primer brands when testing primers with the same bullet and powder charge.

It won't take any effort to segregate your loads with the different primers. It's just too easy not to mix them and your ammo and your confidence in your ammo will be the better for it.

I have used different primers in my 38, 9mm and .357 loads over the years and I have to admit that there is not that big a deal with my accuracy or chrony fps to make me stick with just one primer.

I will state that in the 357 Magnum, a hotter primer might help you out if you use HS-6 powder but that is the only time that I noticed a major difference.

Usually there is little performance difference in primers, but sometimes the difference is significant. There's no good reason to mix primers and it's not advisable to do so.

CCI primers are usually shiny silver and Win primers are usually bronze colored so if you make note of it on the bottle you should not have a hard time telling them apart when you shoot them.

For typical range fodder I have no concern mixing primer brands.

For precision loads, "Everything" matters.

I weigh and measure most every component. I stay with the same batch of primers and powder for as long as possible.

Primer brisance varies a lot and can have a significant impact on pressure as well as performance, even in the same class of primer.

Substituting primer brands in a known load is something that should be done on a trial basis before you load up 1000 plus rounds.

Mixing primers is, IMHO based on 43 years of handloading experience, farm animal stupid. You'll get by with it for awhile, but you'll eventually encounter a cartridge, powder, load, and primer combination where the end result will be a kaboom, and then you'll be posting on some internet forum asking other self appointed experts who are still high up on "Mount Stupid" of the Dunning-Kruger curve, why it blew up.

Just don't.

In handguns, not a huge diff among brands. In rifle, primers can certainly affect accuracy. Certainly dont mix mag & std, just not a good plan if working with anything pushing max.

I must be a real renegade on this.....prairie dogs in Montana just don't seem to care WHAT primer I used......I grab whatever is on sale and then get as many as I can afford....Winchester, CCI, Federal, Remington, S&B etc.

To the total shock of many precision shooters, I even shoot mixed brass!!
Prairie dogs don't care about that either...go figure....

My load is no hot rod (25 gr of H335 and a 55 gr RNSP bullet) Point of impact/point of aim remains the same with ANY of the primers in my Savage Axis .223. Almost 8 thousand rounds later it still shoots AMAZINGLY well!!

As far as blowing up a rifle because you interchanged primers.....hogwash. Never seen or heard of such in over 55 years of reloading and 30 years of Service Rifle matches.

Randy may mix and match primers, but you don't want to be an "Occupant" when he visits the prairie dog patch. Talk about a 'career limiting event'!!

You have a point.

Here's a little humor to the argument:

It is so easy to keep your reloads separated by primer type that "Even a cave man can do it" to quote an old commercial.

Primers, just like most other reloading components, differ from one manufacturer to another. Much of the time the differences are small, negligible, but there are differences. Some makes of primers are "hotter" than others affecting chamber pressures (slight in most cases, but definite different results possible). Some cups differ in hardness and possible differences in reliable ignition can happen. I keep my loads separate by components, different manufactured bullets, primers, and brass for the same basic load (I have Winchester primers and CCI. I keep the Win loads separate even though all other components are identical. I have Nosler JHPs and RMR JHPs of identical weights and very close profiles separate, even though everything else is identical). Make any difference? In my mind yes. A huge difference in performance or accuracy? Probably not, but I still separate...

Some rifles, calibers & loads are very forgiving. Some are very finicky. My 338-06 is an example of finicky. It shoots fine with most primers, a bit over 1moa. With cci br, it is 3/4moa, very round group. My 260ai is very foregiving with just about anything shooting sub moa & switching primers gives a minimal accuracy advantage. Depending on accuracy std, distance, yeah even mixed brass works in most.

And now a word from our Sponsor about Surgically Clean Brass. Time for Rule3.

OK thanks for the intro,


There is no reason to mix primers, use one brand for a bunch of reloads, use another brand for the next bunch etc.

I use 4 different brands. My preferred brand is Federal, but will use Remington, Winchester and CCi depending what's available and what's on sale. For my needs, I see little to no difference except for cost and availability. While I will use Winchester primers, I still hold a grudge against them for removing the Nickel plating.

If you are shooting for money or trophies ... separate them , consistency wins matches .
If you are shooting at the range , separate them ...consistency = better groups which make you appear a better shot .

If you are going to reload , be consistent and load good accurate ammo .

The books all say to use the exact primer specified in the recipe, but then many recipes do not state a primer type.

Old school target loads for wad cutters and utility loads for SWC’s are standard and float around as “X.X grains of Bullseye with a XXX grain WC bullet.” Those loads have been used millions of times by thousands of people. Primer type cannot be a safety issue or we would know. If the recipe is trying to squeeze the last 100 FPS out of a rifle cartridge to get it into “Elk Class” then the primer type is probably crucial. And obsessive target shooters care about everything!

I don’t see a downside to loading 100 mid range 38 specials with Federal and then 100 with Winchesters and not keeping track. Until you get a bad brick of primers. I’ve never heard of a bad brick of primers, in fifty years of reading gun magazines. It is also just as easy to consume one brick before opening the next brick.

Common sense and reality are so ignored by perfectionists. When the wind starts blowing, all bets are off. The best primers are the ones on your shelf when you need them, or on the store shelf when you want to buy them. Primers have not been an issue for me since November 5, 2008. Buy early, buy enough, and don't change your range times. When the Price Is Right, buy some, buy more, or buy all of them.

First of all, thanks for all the responses.

Secondly, I am just loading to punch paper, in both rifle and pistol. I don't own a chronograph and probably never will.

Third, I load on a single stage press and still weigh every charge. I also measure every piece of rifle brass. I am very careful and always will be. I'm not in a hurry.

I started with CCI, but components come and go and we can't always get what we want. I saw a brick of Winchester and I bought them. I sat in front of the TV and used a hand priming tool and seated them. I had forgotten the color difference so I can easily tell them apart from the CCI. That being said, the Winchester ones are now sitting in a large freezer ziplock bag, apart from my CCI ones. When I have loaded all of the CCI rounds, I will begin to load the Winchester. As far as "not mixing", are you saying I shouldn't even put the two loaded rounds with different primers in the same magazine? I use the same amount of powder, 26 grains (I believe, I'd have to check) of CFE 223.

I did buy some CCI small rifle magnum primers by mistake. Boxes look so much alike. I was told here not a problem with AR rounds, especially since I load lighter. I haven't even touched those yet and will not for some time. I'd have to load another 2000 regular CCI before I even got to them, and I still pick up bricks as I see them, so it might be years until I get to the magnum. Matter of fact, I recall being told Federal are softer primers so they're great to use. I have several bricks of those for small pistol primers. I'm quite sure I have mixed them. No issues.

Are people here saying they only load one primer, ever? Even when components are scare?

And by the way, I am meticulous with my brass cleaning, too! Wet tumbled to get them super clean inside and out, then after they're dried in a brass dryer, a quick dry tumble to allow them to cycle through the press more smoothly. Rule3 was extremely helpful when I got started 7 years ago, and I take his advice with most things reloading, but I just like the look of shiny brass!

I have loaded for over 60 years. Mostly shotgun and rifle. I have now stopped due to age and eyesight. If you are loading full loads you should keep primers separated and consult your manuals to keep it safe. Not sure about low end loads but I have heard that they have their own set of issues especially in large capacity cases like magnum rifles.
I would not load any formula that differs from modern manuals for safety sake.
