[QUOTE="J E Custom, post: 339861, member: 2736"] That much change in velocity would indicate to me that you had a bad primer. Some times if you handel the primer with your hand it will get contaminated with skin oils and doesn't ignite properly causing a delayed ignition and a slow flame propagation. The other thing that happens in colder weather is that the fireing pin and spring have to much grease on them and it will slow or stop the firing pin from striking the primer. but this will not change the velocity like in your case but will cause hang fires. There are a lot of other possibilities like under sized cases, poor primer fit,weak fireing pin spring and/or a short firing pin and deep seated primer combo. J E CUSTOM [/QUOTE]
