[QUOTE="David P. Herne, post: 7096, member: 29"] Len, I'm so glad you started this thread, 'cause this phenomenon drives me to drink at times! You probably know this well, but one thing that I've been trying very hard to account for (ever since Dean Michaelis emphaticatically lectured me about it a couple of years back) is the temperature of both the chamber/barrel and the ammunition at the time of firing. And this is reflected in the results I've obtained after chronographing the exact same load under virtually identical climatic conditions, but with drastically different chamber/barrel and ammunition temperatures. For instance, the difference for me at 1000 yards in my .300 WSM after taking my ammunition out to the range in a cooler and then promptly shooting a few rounds long before they warmed up, as opposed to letting them bake in the afternoon sun of southeast Texas for 30 minutes prior to firing, meant a gross difference of about 12-14" rise on the target. The difference in the temp. of the respective groups in this case was certainly > 30 degrees! Regards, Dave [/QUOTE]
