I use VV N160 in my 6.5x55 with great results.
Mike.. how much IMR4831 are you using and what are your final cartridge dimentions?
Cheers
Paul
Paul,
I am pushing the 142gr SMK's using IMR 4831 @ 43.5gr - 44.5gr. My OAL in 3.050"
The 43.5gr works nice in my Tikka T3 varmint - the 44.5gr does not show any signs of pressure but the groups at 1000 are not as good as the 43.5gr groups. There is no discernible difference in groups between 100-600yds
Mike
I've found that N160 gives good results with Sierra and Hornaday bullets.
