1/2grn different in .223 for 55 grn pill
same at 69 grn pill
22-250 70grn pill same start 1.5grn diffeence max
point Im making is that IF YOU FOLLOWING GOOD RELOADING PRACTICE eg starting low and working up...or just running with mild load...it will make no difference worth a damn...in fact I would go so far as to say if you dont fcuk around with a chronograph you would never in a million years pick a difference....
same thing happened when the folks at ADI changed AR 2213 into AR 2213SC.....folks got all antsy about data...all they did was cut it shorter sticks..thus the SC=short cut
made for easier metering in spoons and throwers.
look up data for 2213 and the hogdgon equivilent...and data will be higher for the Hogdgon powder yet it is made in same place just put in same jugs with different label.
for this fella in his 303 brit with LEE spoon mild loads it wont matter a fig.
