Hopefully thats enough disclaimer.

We all know that large magnum rifle primers are “hotter” than a small pistol primer. Particularly a WLRM compared to a Rem 5 1/2.
Todays test used a 308 I have built for myself. Rem 700 action, Lilja barrel.
First string: Starline brass, Rem 5 1/2 primer, 34 grains H4198, 168 MK. Average speed for four five shot groups was 2403 fps. This load is in the Hodgdon book.
Second string: Hornady brass, WLRM, 34 grains H4198, 168 MK. Average speed for four five shot groups was 2394 fps.
Slower with a magnum rifle primer than a small standard pistol primer.
Both loads shot well, neither being better. If I had shot both strings at the same target, group would have been less that 1.25 inch.


Any difference in case capacity between Starline and Hornady?

Thanks,
