My brother and I have both picked up m700 lr rifles in 300rum over the last couple of months. They are both shooting sub 1" groups at 200 yards with nearly zero load development. We simply took the 175-180 grain bullets we wanted and stuffed the rem cases with enough rl25 to net about 3300 fps. Fed 215 for the fire as usual.
I still have to work up a load with 220-230 grain pills for my rifle; I have 600 of the 220 nos and 225 hdy on the shelf for the rifle already.
His rifle has worked flawlessly from the get go... My rifle needed a bit of milling on the extractor rivet to get clearance for ejecting fired casings; otherwise the rifle was fine from the start. It wasn't enough of an issue for new brass to even notice the problem, only casings with many shots on them from a previous rifle.
As to the trigger.... my rifle has a decent enough trigger that I will not waste the money to replace it. It feels nearly as good as the Timney in my 7stw.
