So I have a load worked up with my .308win, with Varget, that shoots great when it's a certain temperature zone outside. when it gets hotter or colder, the groups really open up. This past weekend I tried a load of 8208 with same bullet and it shot great again. Temps were in the upper 30's. My original load using varget was up around the 1" size since it was cold. now to my question. Is the new IMR8208 more stable in temp differences than varget is? If 8208 is less temp sensitive I guess I am going to have to change powders. please let me know what you guys are running into.
