Recoil impulse comparison test
Shot off a few rounds to compare this afternoon.
I live out in the country, but am considerate of my neighbors, so only shoot a few at a time.
First I shot one Buffalo Bore .38 +P 158 grain Keith Hardcast outdoorsman in my 4" Ruger Security Six.
Then I shot an Armsco .357 (midrange power) 158 grain to compare recoil impulse. Both shot were almost identical in recoil impulse. Which leads me to believe that the BB load is just about low end .357.
If you read the numbers, out of a 4" barrel, the .38 +P is running 1146fps and 460 foot pounds muzzle. That's pretty close to what the low to midrange .357 is running and the recoil impulse confirms my theory.
Then I tried three rounds out of my LCRX with the new hogue tamer grips (the ones that come on the 3" LCRX) and it was stout, but controllable. The recoil impulse was higher of course because of the much lighter weight, and the noise and blast were more.
Note: four rounds loaded, and checked the unfired fourth round for jumping crimp, and it was fine.
I'm pretty sure the .357 LCR is next on my list, if I don't get the Ruger 77/357 rifle first!LOL
