Does anyone have any experience loading 100 grain bullets in the .243 winchester with the new imr 8208 powder. I really like the idea that this powder isn't temperature sensitive , since i usually work up my loads in the summer and hunt in the winter.(deer that is). I can find data for an 80 grain bullet,but no heavier! Have worked up a very accurate load with imr 4350, at around 2750fps in 30 degree weather and am sure it would get the job done. But would still like to try the imr 8208.
