Before I go and waste a load of money on powders that will work but not the most suitable, what are people using in their .243win with 75gr vmax and .223rem 50gr vmax? I know there is an element of get what’s available but if I can sort a list of most suitable powders I can then see what I can get hold of, rather than me getting 5 different pots of powder and only using a few hundred grains out of them
Powder choice for .243 75g vmax and .223 50g vmax

N140 is what I had been looking at for the .243
I’m not looking at one powder to do both and more than likely I will get one type for each but I don’t want to have to get 2 or 3 powders per calibre as I’ll end up with more powder than Guy Fawkes!
Quite like the look of the Hodgdon Superformance powder as that was the factory ammo I used to fire until it got as rare as hens teeth

Henry Kranks have Superformance in stock.
Ken.
Superformance is too slow , relative burn rate comparable to N165 and RS70.
N133 is an excellent choice for the 50grain in 223 as is 130 and 135 .
N540 is a high energy propellant , work up carefully and you're supposed to use the next bullet weight up for data . I suspect you'll get a low case fill which may well translate into large ES numbers . Pure speculation on my part , but please come back and share your findings.
Personally , I'm not a fan of ball powders . They meter well , but can be a little peeky . I know other people use them with excellent results , I had good results with X-terminator but definitely prefer N133 .
You could ask if an SD member would run QL for the N540 but remember there's no real shortcuts and the results are theoretical , you still need to do load development and adhere to safe practices .

Super performance powder is not the same as uses in the ammunition after doing some research
With those bullet choices in those cartridges you need to or you will have an ‘okay’ compromise. Either that or go up in weight on the .223 55/60 gr if you want to share powder.
