I have a brand new M700 sps in 270 win. I replaced the stock with a B&C medalist with full length bedding block. Trigger set @ 3#. Took the gun out today to shoot for the first time. I tried Rem Corelok, Win power point , Win Sup Bst , Win power max, and Hornady custom SSt all ammo in 130 grain. The Win Super X power point was the only ammo that would group. I got just under an inch with it at 100 yards. All other ammo was horrible. Nothing would do any better than about 3 in at 100. Realy surprised that the cheapest ammo grouped best. Anybody else surprised that only the 1 load would group? All others were just nearly off the page and flying all over. I noticed that some of the ammo was realy hard to chamber , even some of the super x power point that shot well. What would cause this factory ammo to be so hard to chamber ? Should I give up on the other ammo or is there something else I could be doing wrong ? Leupold rings and bases also and a brand new Nikon monarch 3,4-16x50 scope. I don't think optics are an issue.
