The wyatts mag system works excellent, feeds like a sewing machine. I had to do a little work on the adjustable cheek piece on the stock with a dremmel so i could remove the bolt without lowering the cheek piece and to allow the bolt to fully retract for proper feeding with the mag system. The bell and carlson stock is very comfortable and works well. I recommend you call rifle basix. Go to Rifle Basix, Custom Bolt-Action Triggers
and get their # you will most likely talk to clay their customer service is great. I got the ERV_K trigger it is adj 4-20 oz I called him and had him set mine at 10 oz. If you are shooting the 300 win you will need to put some clear nail polish or loctite over the adjustment screws when you put the trigger in or the 300 will beat it out of adjustment, it did mine but i called clay back and he told me how to readjust it i put nail polish on them and it has given me no problem since. I am shooting 210 bergers with 68 gr Rl22 very accurate but a little slow I'm about to try rl25 or h1000 with the 208 amax but anyway i am getting very sub moa 1/2" or less at 100 and routinely 2-3/4 to 3" groups at 400 not bad for a factory barrel and chamber.
