For those fine gentlemen who appreciate our chronographing efforts and for the knowledge derived from such, I chronographed the factory Winchester 38 Spl +P LSWCHP “FBI Load” over the weekend as follows:
Firearm: Ruger 4 5/8 inch Blackhawk
Shot #/MV
1. 826 (yikes)
2. 900
3. 865
4. 886
5. 907
6. 897
7. 910
8. 872
9. 878
10. 906
11. 869
12. 896
13. 918
14. 929
15. 911
Hi 929
Lo 826
Avg 891
ES 103
SD 25
That first shot was unusual but throwing out this Lo (826) and the Hi (929), I get this:
Hi 918
Lo 865
Avg 893
ES 53
SD 17
The Winchester FBI Load above can be duplicated easily in my revolver with 4.7 grs W231 and 158 gr SWC…a sound and accurate load in its own right.
