thanks for the response guys,
Efficiency is certainly a consideration as it needs to be an all purpose rifle, we have a big feral hog problem here so affordable effective ammunition that is easy to shoot in volume is a consideration.
the 270 is a very realistic option, I already load it for a couple of mates so it would not be a big imposition and factory ammo is very available.
the 7PRC looks amazing and if I had the option of having a special purpose sambar/longer range hunter as well as a farm gun then I think the 7 PRC would be it.
if I could ask anyones thoughts on the 308? could I get close to what want out of the Monos and then run cheaper cup and core for farm duties?
Regards.
