Has anyone seen a grouping difference between these two in the .223?
The extra 200fps doesn't mean much too me, but I'm wondering if there's a pattern of better grouping with either. I just bought a box of the S.P. just to see if there's a difference in my R15 and I'm wondering if anyone else has tried a comparison in their rifles. I don't see the two grains of weight difference (53 vs 55) making a huge group size change.
