RE: Does anyone know 243 load that is above max?
I have had good luck with these 2
IMR 4350 (40.5 gr) and nosler 100 gr partition
RL 22 (41 gr) and 100 gr partition
they are for my wifes .243 and she gets 1.5 moa at 100 yards great for antelope and muleys i am sure they would take out a whitetail also
however i will for warn you what shoots great in on rifle can be a total different ball game in another
i would suggest you get the reloading manual for the bullets you want to shoot and work up a load for yourself it is more fun to know you worked it on your own
if you need a page or two of loading info from nosler or speer shoot me an email and i scan one for you
