James I don't have the sps in 7/08 but do have the rem classic with 24 in barrel so should be about the same.This summer I played with the hornady 120 in HP and spitzer and they shot so good I tried the spitzer on a deer and at 240 yds it did well but hit farther back than I wanted because the deer waswalking pretty fastaccross a power line,it went about 75 yds before pilling up.Bullet made complete pass through but there was only some hair at the impact and no blood for the first 25 yds.If it had been standing still and I placed the bullet better I believe it would have worked well.These were loaded with [email protected] grs and both shot more than a couple groups at 300 yds less than2 inchs,with the spitzer shooting a little tighter than the HP.This load is 1.5 grs over book but still didn't get up to what book says for 45 grs.I got 3012 fps.
Have used the 139 sst and they worked well also on deer.
Worked up some loads with the barnes tsx you may want to try.
