My question is I used up my last jug of h4350 i have a load for my 260 and a load for my 6x47, now that I have to go and get more powder is it in my best interest to do a ladder test again on both loads or just take it out to 300 yards and shoot it and see how it shoots. Do you think by the different lot numbers make a huge difference for accuracy or could it cause higher pressures or slower,faster velocities.

I dont think I would do load development again. You should not need to. Maybe just drop the charge a little bit to be safe, check it with a chronograph and see where you are. Your new batch could be hotter or cooler.

FWIW I have never redone load development b/c of a new batch.
