Seems the 6x45 bug is in the air. My barrel should be here this week. 20" X-caliber 8tw. I have a bunch of H335 and ordered some 58vmax's to start out. Everything I've read shows 25-27.5g for this combo. The Hogdon website doesn't list data for this combo either. Any suggestions or other good loads would be greatly appreciated!
 
I ran this combo in QL and it is showing 28.6 as the highest load under max pressure. As always, start low and work up.

I shoot a 65gr v max out of my 6x45 with 26.5gr benchmark and Tula mag primers I'm getting 3130 fps
I tried 55gr blitz kings but they couldn't beat my 223 shooting 55s.62- 65 grains seemed to be where the 6x45 really starts to beat the 223 in velocity.
