Rem 7½ small rifle BR primers

[OkieMike]

Just wondering how they stack up against the others like FGMM and the CCI BR primers?

I'm not expecting life-altering difference... Just curious what other folks' experiences with them were.

I had good luck with them in .223. Don't have the numbers in front of me, but they brought my SD down some compared to the CCI. YMMV

I've used them in a 30-20 and 22 Hornet T/C's . Probably more to your question , I've run several tests in a 20" AR and with several different powders , the 7 1/2's 90% of the time shot tighter 5 shot groups at 100 & 300 Yds when tested against 205M's, CCI 400 & 450's.

I have some old stock 7.5's and have developed good loads with them.

However, if I use them in x47 lapua cases that have previously used CCI 450's, for me they seat much easier/more "loosly" ie smaller diameter IMHO

Excellent info gents. I thank you.

May have to try 1000 just to see.

The REM 7 1/2 is one of the favorite primers for AR15 Service Rifle Pet Loads.
