I just registered to post this (been lurking for a few months)
I bought some Buffalo Bore 38+p heavy for SD loads (158gr LSWCHP) in my S&W 642 (+P) Airweight. 1-7/8" bbl.
However, after shooting these sticks of dynamite, i decided to load something close but not THAT hot. The recoil was painfull and follow-up shots would be difficult. But it chrony`d at 1024 avg.
I read some excellent data on HS-6 by ArchAngelCD for FBI replica loads.
I bought some RimRock 158gr LSWCHP and put them atop some HS-6 with CCI-550 Primers and I got 860-900 (avg 876) ft/sec.
Recoil still had some sting but was manageable.
No leading, no flash and no smoke. Primers looked good too.
only thing I noticed was a little discoloration on one side of each case?
Anyway, just want to say thanks to ArchAngelCD and others that did the load testing on this great combo.
Question: does this 40 ES sound ok? ( My cheap chronny doesn't do SD)
