Here is my load for my 300 wby
Barnes TTSX 168 gr
Rl 22 86 gr

two different primers and 200 fps faster and extractor marks with the Federal primer (L) compared to the Winchester primer. I didn't notice the extractor marks until I actually blew a primer with the Federal load. I've never seen that much difference in pressure from just a primer switch. Is this to be expected or is this an anomaly? The load is 1 gr below max also.
