RE: Does anyone know 243 load that is above max?
deerslayer just a word of caution. Max is there for a reason. I've only ever had 2 rifles that shot well at max or near max loads. My 270 and 300 WM.
Some rifles just don't like max loads either. Don't be overly posessed with velocity. Accuracy is more important.
My 243 just loves 40.5 gr. of IMR4350 behind a Hornady 100 gr SP.
