None of the above loads showed the slightest pressure signs. In fact, I tested significantly faster loads (as much as 100fps) with zero pressure signs in all of the above loads but prudence dictated I back off to saner levels...

I've been lucky with this rifle - It was a barreled action purchased from SAS using one of Burley Boy's barrels. It shoots pretty much everything accurately, but the 123Scenars are SOOOOOOOoooo easy.

RL17 has been very temp resistant for me in the Creedmoor, loads chrony the same velocity from mid 20's to 80's. I don't have any "real" cold in AO, some people claim less favorable performance when the temps get near/below zero.



Good looking loads.


Anyone try Superformance?
