Remington 7 1/2 BR primers

[kyreloader]

I use CCI 450 primers, but with the shortage, rem 7.5 were the only SR primers available at the local stores. I pick up some to try for club shoots and early season shoots in my 6.5x47 and Dasher.

Anyone using these primers? What is the forum's consensus about the utility of these primers?

Thanks guys.

You will not go wrong with the Rem 7.5 primers. They were the choice of short range bench rest several years ago.

I use them in my 6x47Lapua live varmint rifle. They have a tough cup and don't show pressure as bad as the others.

They work fine.

I use them exclusively in all my small rifle stuff, and am very happy with them. I've tryed the other brands and always go back to the 7.5s

I recently made the switch from CCI 450 primers to Remington 7 1/2 primers in a Savage .223 and didn't notice any difference at all. Same powder charge delivers identical accuracy.

Me too, to quote German Salazar, they're little flame throwers.

Great primer initially produced for the .17 Remington I believe. During the last shortage Remington was the only manufacturer that kept up with demand. I learned to love them at that time and they are my go-to primer for the 6 and 6.5X47L also the .308 Palma cases in our NE weather.

They have the same cup thickness as the CCI 450. I've used them with ball powder, H335, and they work very well providing good ignition and very tight groups.

The Lyman Manual 47th Edition lists them as a small rifle "magnum" primer which suggest they have a similiar ignition capability of the CCI 450 which is a magnum primer also.

I've used them with stick powder also, namely IMR 4198 and IMR 4895 but they didn't group as well as with Federal 205 match or standard CCI 400 primers shooting a 223 and 222.

They are hotter, so if you subscribe to the "tune is velocity specific" school of thought, you may want to rework your load. I don't know of anyone in the short range benchrest game that has used them for a looog time. As far as when they were created, I believe that it was for the .222 Remington because all of the cartridges that had previously been with small rifle primers had pressures that were more like that of the Hornet, quite a bit lower. For varmint work, I would not worry a bit, and for certain applications where the case it on the large size for a small primer, powders that may a bit harder to light, and any marginal situation in cold weather, they might be better than their milder cousins.

I've used them for a long time in various rounds. IMHO they are a must in the 17Rem.

For bench shooting they have worked better than anything else in some loads that I've tried them in in my 6ppc and 6br. As previously stated they may be a little warmer than some other primers, so always a good practice to back off the powder a bit and work back up if you need to. WD

Remington turns out some very good lots of those primers.

Remington 7 1/2 is my go to primer on anything with a BR case. This primer seams to work good with BR cases. Yes this primer is considered a magnum primer, and if you look at Precision Shooting's Benchrest primer, they did a comparison of primers in an article in precision shooting some time back. If you look the Rem 7 1/2 has one of the biggest flame patterens of all the primers tested.

I use nothing else in an AR 15 and use them in in my 6.5x47 L. Really like the 71/2.

Great primer in Dasher. Cup alloy is not as hard as cci 450. Even with well fit 062 firing pin the 7.5 will show cratering well before 450. Im not a fan of pushing them hard. But if you do, be carefull. Good luck Lloyd
