I bought a 11FCNS in 270WSM about a month ago. My first Savage and my first WSM. With it I picked up a few boxes of Winchester 140gr Accubond premium ammo. Needless to say, I was pretty disappointed with the result I got with this ammo at the range. Groups were 1.5-2.5" (mostly over 2")......not what I was expecting given all I had read and heard about out of the box Savage accuracy. I have not tried any other factory loading.
I picked up some 130gr Barnes TSX and Hornady Interbonds. Using Accurate's MagPro powder, both bullets gave gratifying results with a slight edge to the TSX's. Watch Accurate's data on MagPro, my gun showed pressure (flatten cratered primers, bolt marks on the case head, very hard to open bolt) at a full 2.5grs less than Accurate's max (75.5gr). I have settled on 70gr to deliver an average velocity of 3250fps. Groups with the TSX's have been between 0.5-1.1" . Interbonds are only very slightly larger on average.
If you want a light gun, then the 11FCNS should fill your needs. I hunt whitetails from a ladderstand over feed plots, so weight is not a huge consideration for me. If I had it to do over, I would probably go with the 12FVSS with the 26" heavy fluted bbl. For my purposes, the 11FCNS in this caliber is a little light. You will feel it at the end of a range session after shooting numerous loads.......and I tend to shoot a lot per session.
The bbl on my gun fouls quickley and easily......something I'm sure will decrease as I further wear the bbl in. A dirty bbl does not seem to bother this gun too much, but it will tell me with groups opening up that it needs cleaning. I do like that magagzine set-up. It is a single position feed, but allows for top-loading by pushing the ctgs down into the mag. Magazine capacity for the WSMs is only 2, for a total of 3.
In sum, I was disappointed with the results of this gun and the factory Winchester premium 140gr accubond ammo. Once I made up my own loads, this gun began to show potential. Overall, I am pleased with the purchase and this Savage has delivered the expected bang for the buck.
