7/8/15 The temp was 70 degrees for the whole session. I figured if it doesn't put three close, I'm finished with that primer. I fired three groups using the Nosler ABLR 129@ 3.408" and IMR 7828 @ 68.0 with three different primers.
The CCI BR-2 produced a three shot group of 1 1/8" so I fired one more. It enlarged it to 1 7/8".
The Remington 9 1/2M primers produce a three shot group of 1 ½" so didn't fire anymore of that one.
The CCI250 Magnum produced a tree shot group of 5/16" and a four shot group of 7/16". The fifth shot opened the group to 3/4". I accept this as a gift from God.
