I have a Stevens 200 in 7/08. I have used the same flimsy stock that came with it since I bought it- almost always shooting off of a bipod. I developed a load a couple years ago that I have accumilated a large amount of data with. 150gr SBT, and 40.6gr of varget (Avg FPS was 2647). The load has been quite consistent in the varying temps hat I have shot it in at 800ft ALT. I actually didnt notice any difference in flight or impact when I went out to WY last year for a hunt and we went to the foot hills and did a rock shoot at several different ranges. This was at 4600-4800ft ALT.
My buddy just purchased a savage M10 FP-SR in 308 and changed out the stock. I noticed that the factory stock he took off the gun has the same screw spacing and same blind mag set up as my stevens. The stock (not an Accustock) was much better and much more rigid than the one that came with the Stevens. So I thought, "What the hec!" and decided to put the stock on my stevens to try it.
I took the rifle out to rezero it and decided to run the loads over a chrony. The avg FPS is now at 2710. At first I though that I got a hot batch of Varget. But, I have never ran into this increase in FPS before because the data has pretty much stayed the same in whatever temp I shot it at (generally out to 500yds).
Now with this stock is more rigid and has much more free float around the barrel (the stock I put on was cut for a bull barrel and I am toting a sporter weight barrel). Could the new stock be causing the FPS to increase due to different contact/ no contact with the barrel lug, action, and barrel?
