N560 and 75Gr V-max in .243 winchester?

I would be prepared for a large daytime muzzle flash. When I tried N56O in my 24" 6.5x55 it took bullet weights of 129gr before this stopped. 100gr and 120gr were bright, loud and not pursued. N560 seems a lot more prone to muzzle flash than N160.

N560 is to slow for 75gr bullets
N550 is much better
neather one comes close to Varget for less then 80gr bullets
Varget=less than 80gr
4350 for 80 to 95 grain
4831 for over 95grs
i've been keeping records on 243 loads for 23yrs and these 3 powders work the best

I've never used N560.

For me, H4350 gives better velocity with identical accuracy over Varget with 70 & 75 gr. bullets. In my 22" bbl'd stainless Win 70, I'm getting over 3,500 fps with the 75 gr. V-Max.

that's a fast barrel you've got there!
3300fps is closer to what i've seen over the years with max charges of H4350 from a 22" barrel and 75gr bullets.
