[QUOTE="tbrice23, post: 1370271, member: 59502"] Doigduey, FWIW,a couple of years ago I had a good safe load for 264wm with Retumbo in 50° temps. Right before my hunting trip the temp droped to 20°. The same load with the same component lot# blew my primers right out of the case! Velocity increase 150fps. I blamed the barrel for its stress relief (or lack of) for bore contracting. It still baffles me to this day. But the more I think about it, maybe it was the Retumbo, the cartridge and the barrel. Slightly different scenario but just a thought. [/QUOTE]
