Powder choice for .243 75g vmax and .223 50g vmax

N140 I have been using with 70 grain in 243 ,

N140 is what I was after but it seems it is completely out of stock almost everywhere and no updates as to when it will be back in stock. Had to settle for the N540 for the .243.

If anyone could run QL for N540 and 65g + 75g vmax in .243 I would be most grateful as there seems to be hardly any load data out there for this combo and I want to have a bit of an idea when I start doing load development

I use 39.1gns of reloader 15 with my 70gn Blitzking for a average velocity of 3133fps. Federal 210gm primers. Seems to work well. I'm lucky in that my 308 also likes reloader 15 so no need for multiple powders.

Try starting another thread asking if someone would mind running QL for you .

I got great results with n140 75gr Vmax with 243.

39.9 of N140 behind a 75gn vmax works a treat in my howa
