Re: Remington 9 1/2 magnum primers

From the primer heat charts I have seen they list the 9 1/2's as the coldest.
1 fed, 2 win 3 cci then 4 rems. I remember seeing an actual high speed camera
flame test on them so it wasn't conjecture. Google it and you'll find it.

I don't know. Might be availability. They have been harder to find around here for the last couple of years but I have a box of them to try in my 7mmMagnums. I also have a box each of Fed215, CCI250, and WLRM to try in them.

I use the Rem 7-1/2 primers in my .17 Remington because they are better in a high pressure cartridge like the .17R. I have two bricks of them which is probably a lifetime supply.

Re: Remington 9 1/2 magnum primers

I found the R 9 1/2 to be better under max load conditions than the Fed 215s in a 7mm Wby. You do not always get the most uniform ignition with the hottest primer. Sometimes less is best.

Thanks for the data. Here is another interesting read on primers: http://www.chuckhawks.com/primers.htm

And some testing: http://www.the-long-family.com/primer_study.htm

Re: Remington 9 1/2 magnum primers

I had some laying around and started using them in my 7mag when the Federal 215M's got hard to find. It seems to like them.
