Mini 14 223 primers

[Gibbons85]

Can 6½remington sr primers be used for my ruger mini 223. I used 22.8 gr. Of acc. 2015 with 55 gr hornady FMJ-BT and noticed some dimples, and one pin hole in my primers. I am new to reloading and appreciate any insight

NO! You will mess up your bolt if not get hurt. They are for low pressure rounds like the Hornet NOT the 223.

There is a very good chart in this article that will help you with primer selection in the future.

Very informative article my starting load was 21.5 gr. Which would not eject properly.

Excellent information my starting load was 21.5 gr which wouldn't eject correctly. A fellow loader told me my mini was rated for 556 and just needed a heavier charge. Needless to say im glad to have joined, and appreciate the reply

Been loading 25gr of Benchmark behind a 55gr JHP , using a Win SRP with no adverse affects in any area . And the target thinks it's a pretty good load , too . Avg. a inch and a half group at 100 yards .

I have some win srp according to the link jim shared they are .001 thicker, but i think ill just try and find some bench rest primers that are about .005 thicker

Just use SR Mag (if you can find them) and don't worry. I switched to mag when the Big O was in office and never went back.
