Starting to test and compare primmers, I've been using CCI, have any of you tested the differant primmers and which you came up with. I load for 30-30,25-06,243 and 308. Thanks guys

i used CCI and Remington on the same load and found almost no difference. the group was shaped a little bt differently but size was unaffacted. in fact, the shape could have been me, for all i know.

I can't tell much difference in the larger calibers I load, .270, 7mm-08, 308, 6.5x55, & 30.06 but my Remington .223s seem more finicky. My Rem 788 likes Winchester primers and the Rem. 700 likes Remington primers. I also got good groups with CCI magnum primers when using the larger grain stick powders. All guns are different and the powder/primer combination makes a difference so you will have to experiment to see if it makes any difference in a particular gun. Thats the fun of reloading.

I don't there is much difference between brands. Using large rifle primers as opposed to large rifle magnum primers, for instance, may make a difference.

All depends on the paticular rifle..I use Remington 9-1/2 for most of my loading...very consistant from the 243,25-06,270,308,30-06,338-06,& 45-70...I'll let you know how it works for the 280 shortly..

I use Winchester component's for the most part. However loading 7mm mag the other day started to use some CCI mag primers and found them A LOT harder to set than the Winchester. I found the same with the 243. They may be bigger in size?

I used to use nothing but CCI primers, mostly because when I started reloading, that's about all I could get consistently. They worked pretty well for me until I reloaded for an older Winchester 94 in 32 special. Would have misfires, perhaps 3 or 4 in a box of twenty. At the time, I ascribed this to the age of the gun, even though factory loads worked with no problems.

A couple of years later I purchased a Ruger 77 in 35 Whelen. I had the same misfiring problem with this brand new gun. I did some research and read an article that claimed the CCI primer cups are made of slightly thicker metal than other brands, and are thick enough to cause misfires in some guns. I think the article recommended Federal, so I switched to Federal primers and had no more misfire problems. I haven't yet checked the 32 special, but I'm guessing the same would apply.

I realize this has little to do with accuracy or performance, but if it doesn't go bang...

Well, I have always felt that the original McGuffey's were the best primmers available.

However...

If you intended primers, then I always start with Remington, and after I find the best load I then substitute other primers of different makes with the same load to find if any cause a noticable change in performance. And, I have...

In large rifle primers all the brands have the same cup thickness. In the small rifle and pistol primers there is a large difference in the cup thicknesses. I think the thinnest small pistol is .017 thick, CCI's have both .020 and .025 thick cups depending on the model, the other brands are simular. Look here for all you will want to know about small rifle primers. Larry http://www.jamescalhoon.com/primers_and_pressure.php

Good article. Thanks. I used to use CCI also. Only have a few Large Rifle Magnums left. Small rifle primers I use Winchester, Remington 7 1/2, and Federal. They all have their place depending on the case and the powder.

I shoot a lot of silhouette. Once i work up to a load that will give me around an inch at 100 yards, I will try a different primer to see what happens to the group. Sometimes it is suprising to see the difference in velocity and accuracy by just changing the primer.

I have a DW revolver that loves 1680 powder and Rem 7 1/2 primers. My shooting buddy has same gun (1 serial number different) and had to use 2.0 grains more 1680 and Winchester primer to get similar velocity and accuracy.

I have an XP100 in 7TCU. At 100 yards H335 and Remington primers gave me a nice 1" group. I tried different primers. Federal gave me about a 1.5" group. Winchester gave me about .5" group.

You can go from mild to wild in smaller cases like the hornet, 30 carbine, etc, just by changing the primer.

I have several similar stories with Large Rifle primers also. They are not the same. If using near max loads, be careful if changing primers.

I ran into a batch of 1000 Remington primers that had at least 4 -5 duds per 100. I quit using them and have been using Winchesters ever since.

Thanks guys, I loaded some cci and winchester for my 25-06, The winchester shot a tighter group. Thats why I like reloading, experamenting is best part of trying to get them better. Love to make them go bang.
