Default CCI BR 4 primers

From reading CCI's web site: they should be used just like CCI 400 primers, correct? I have an opportunity to buy 4x1,000 boxes.

From web site: "Use the same data as CCI Standard (non-Magnum)
primers"

They are just like the CCI400 primers only more consistent ignition from primer to primer.

they are slightly thicker. you get the benefit of higher pressure handling capabilities over the 400's.

In my 17 Remington and 17 FB I cannot tell the difference between the BR4's and the 450's, either one shoots to the same POI in both cartridges. I have always tried to get the BR4's but the 450's act the same for me. Larry

The BR4's and the 450 use the same cups.

It's been over a month since all the big suppliers have ran out. I'm beginning to just wonder a little. I'm smelling government or BS in the air..........

From what I was told by CCI, the BR are the equivalent to the 400, the 450 are mags. It is a little confusing.

Default Winchester Small Rifle Primers

Winchester small rifle primers are so good that their standard primer WSR is also their magnum and benchrest primer all in one unit. I bought 14,000 WSR primers 5 years ago. I shoot them mainly in my 22 and 6 PPC benchrest rifles. I also use WSR primers in my .222 and .223 rifles. In my 6x47 Lapua I use WSR primers exclusively. I have Fed 205, Fed 205M, Rem 7 1/2, and some CCI. I have no favorites in primers, they all work with loads that don't push the envelope of going past a node and showing extreme pressure signs. I back off my load and find another node to not be in that extreme pressure. This node and extreme pressure stuff I'm talking about here goes back a hundred years or more before WW 1 in the time of Pope and Mann. We are not genius level they were.

It's a good primer, get them. I use the BR4 and Rem7-1/2BR interchangeably...they're both magnum primers. The Win SR primer has a thinner cup. Not for high pressure rounds, it isn't and never has been considered a magnum primer.

Default WSR is the Small Rifle Primer WLR is the Large Rifle Primer

The .220 Swift is in the magnum pressure range with some loads in the 53,000 psi range. Not hypo insano pressures of 60,000 psi but at velocities over 4000 fps I would say the Swift is a magnum. Reloading manuals of different makes use Remington 9 1/2M and WLR primers both for Swift loads. The WSR is the same cup design as the WLR primer suggested for 220 Swift loads. PPC loads approach 55,000 psi and WSR primers work just fine, been there do that.

Magnum is a state of mind with some rifleman. Not much to do with riflemen attempting to get productive loads that harvest game and group well on target. Not sure what my 6x47 Lapua with a healthy load of 4350 is on the numbers scale of psi and fps don't care. But I know what it does on 600M targets, they fall down fast. I use WSR primers with my Lapua loads. At 600M I am flattening prarie dog size silohuettes 10 in a row in swirling winds that would challenge most riflemen. Proof of a cartridge designated magnum or not is in the field not on the chronograph. I do feel those with chronographs you have a good tool for load development but not the only tool.

I believe the 400's and the br-4's are the same mixture, but the 450's are hotter ( different anyway ) I shoot the 450's in my 6br 1-8 tw with the 105's. have had good luck with all of them, problem is they are getting real expensive! and harder to find.
