How fast can you push a whisper?

I found a load in the Supersonic listing on the main 1/4 bore page

168gr @ 1958 = 329 PF - That'll work for me

Interested to see what else is around

I have 10k + Nosler Custom Comps so want to use them

If 168 can do it at about 55,000 or less pressure, that that would be better than 175. I picked 175 to work with as I am skeptical that a 168 can really do it within normal pressures in all 16 inch barrels.

Its not much faster than most of the 180 loads on accurate shooter - ~150fps

Maybe when Hodgdon releases its leverevolution and superformance powders in January. I'm sure one of the two will work to get some extra fast loads.

They need one around H110 in order to help.

Is there anyway to find out where it would be placed on the burn chart? It seems like the Superformance ammunition is loaded to a much higher pressure. http://www.hodgdon.com/PDF/SuperLever.pdf

160gr 30-30 to 2400ft/s at 37,000 CUP is pretty impressive though.
