Many years of hunting with a model 70 in 243. First whitetail and then PA groundhogs. Always had great success with IMR 4350 with everything from 60 to 100 grain projectiles, did bed the action and float the barrel but other than that it was stock. The single thing that made the most advance in accuracy for me was the OAL. That thing shot great with 10-15 thou jump and anything else opened up the groups big time. Sadly, the throat is gone in that model 70 and it sits in my safe and I'm not sure what will happen to it.
