Joe,
My test were only on three # 1's, probably not enough testing for any kind of scientific calculation. I can say that in every case the groups were smaller with the Speed Hammer and larger with the Heavy Ruger Hammer. I did not keep exact records and no longer have the targets as it was not that important at the time, the important thing was that all three # 1's shot smaller groups with the Speed Hammer and all shot larger groups with the Heavy Hammer.
I'll guess at it and say that for sure all three were shooting about 1.5 inch groups, after installing the hammers the groups were down in the half inch area, some a bit larger but all were under 1 inch for sure.
The only group that can be verified at this time is the group I shot in the shoulder to shoulder group match, it recorded in as .732 at 100 yds., still under 3/4 inch, the other two events that I shot in and can be verified were score matches, first one was 245 X 250, and the second event came in at 247 X 250, the center ring on the 100 yd. target is 3/4 inch so a good percentage of the 10 shots fired in each of those events were in the 3/4 inch ring.
Like I said, I don't want to say that it was all because of the speed hammer that gave me those wins, maybe I just got lucky, but I'm sure they didn't hurt.
I know, not very scientific, but I'm a shooter, not a scientist or experimenter, my shooting time is limited so once I get a gun shooting good enough to stay in the center ring of what ever target I'm required to shoot at I start practicing, not experimenting.
If some day I have more time I'll start keeping better records, or if they start using targets with a smaller center ring I guess I'll be forced to do more tuning.
