Had been looking at a remington 700 ss 5R in 308 for awhile. decided to cut my costs a bit and am looking at the 700 sps varmint / tactical model instead. the 5R has 11.25 twist, what twist does the SPS have in its barrel? I have several boxes of FGMM in 175 gr I had gotten for the 5R. will they shoot ok in either a 1:12 or a 1:10 twist barrel?
