QLoad for 308 Win., please.

[jagermeister]

If some of you compassionate Guys would take the time to run the following data for me, I'd be grateful :

308 Win. (Lapua Palma Brass) in a 26" - 1 in 12" barrel
RWS Small rifle primers

Powder : Vihtavuori N140 and Vihtavuori N550

Bullets :
- Lapua Scenar 167 grs.
- Sierra MK 168
- Sierra MK 175
- Hornady 168 A-Max

That would make a total of 8 combinations, for which, I apologize.... :mrgreen:

Thanks a bunch.

:wink:

Thank you for the data.


Forgive me if I dare to ask.. .....but would you possibly run also the 155 Lapua Scenar with the two powders, as well ?

Again, appreciate your great help.
