RC: I don't run a 243 WSSM, but I do shoot a fast twist 6mm Rem on a Rem LA. after testing 15 different powders, only one was really unacceptable..
but clearly with the 105 A Max, the 107 Sierra HP, the 105 Bergers, and the 115 Bergers, the two velocity/accuracy champs were RL 19 and H1000...
The 115 Bergers launch at 3250 fps out of a 24 inch Pac Nor barrel with a one in 7 twist, and the 105-107 bullets launched at 3300 fps...( thanks to TexAss Native for pointing out the typo! you're the man Scheissfurgehirn)
not sure how close in capacity the WSSM is to the 6mm Rem, but doing the 6mm on a Long Action, definitely upped the cartridge's velocity potential..
You get all serious and still stick you fugg'n foot in your mouth, edited your post to cover your ass but it's quoted and your stupidity is preserved...TFF
