Went to the range today to try to find a load for my Savage 110 243. I shot Winchester Super X with 100gr spire point, and reloads with IMR 4350 and IMR 3031 using 100 gr. Hornady spire points. The results for three five shot groups are as follows:
Win. factory-2829 FPS ave. widest spread 1.240"
IMR 4350-2846 FPS ave. widest spread .810"
IMR 3031-2807 FPS ave. widest spread .750"
The IMR 3031 powder gave me a little slower speed but tighter groups at 100 yards. The 4350 FPS was more consistent from shot to shot. Hunting ranges will probably not be much more than 100 yds. Which load would you use. I'm leaning towards the 3031 because it uses 7 grs. less powder and is more accurate although just a tad slower. What do you think? I just used the factory stuff for a reference and empty brass.
