powder for short barrel 223

[Rimfire]

I have a 16" 223 and want to shoot 75-77's will the standard powders work or will I have to speed up the powder due to the shorter barrel

That was my first choice, just never tried it in a short barrel and didn't know if 16 inch neeeded a little faster burn

14 or 16 in. barrel really does not make much difference. Varget should work fine.
a 223 is a 223.
