[QUOTE="MMERSS, post: 920581, member: 63748"] I load developed my 300 RUM around 30 degrees. No pressure problems and great performance with RL-33 from temps in the mid 20s to mid 50s. This past week I blew a primer with temps around 0. I usually store the ammo in my pocket to keep them near the developed temperature. Three rounds were taken out of my pocket and placed next to the gun. By the third round after some time sitting outside the round blew a primer with a hard bolt release. It appears RL-33 may be subject to overpressure in extreme cold temperatures just as much as extreme hot temperatures. FWIW something else to consider. [/QUOTE]
