Afternoon all,
I am about to use the last of my win 760 which I have used with Hornady 270 130gr GMX and more recently CX, which performs well. I can get my hands on some N540 for a very good price, which is in the burn rate range for that bullet although no published loads exist (its often listed right next to win 760). Using copper bullets, I pay attention to the velocity.
The Viht site says -
" Vihtavuori N540 is a universal rifle powder for wide variety of medium-sized calibers suitable for both hunting and target shooting. It is an excellent choice for cartridges running from .223/5.56 mm to .308 Winchester and 30-06 Springfield with heavier bullet weights.
Vihtavuori N540 delivers outstanding accuracy with exceptionally clean burning. Due to the extra energy content that all of our N500 series powders include, a velocity up to 30-40 m/s higher can be achieved with the same pressure level compared to the equal in the N100 Vihtavuori series. It is certainly worth trying when using heavier bullets and when higher loading densities and muzzle velocities are needed!"
I know that there is more to comparing different powders than burn rates. So is it worth trying to work up a load in that before I begin the epic Lord of the Rings esque journey around the houses to find some more 760 or 4831?
Your thoughts?
