I found the data interesting and appreciate the report. One thing I didn't see mentioned is if any of the loads produce a low flash. I'm not familiar with BB's FBI load but a friend of mine carries BB in his Model 10 snubby. He told me he selected BB ammo based on its low flash claim. I'm not sure of the specific type of BB ammo he uses and I'm not sure if is +P or FBI load.

Years ago my shooting bud discharged his Model 10 snubby on a coyote that wandered into his camp ground late at night. I don't recall the type of ammo he used but he claimed the muzzle flash nearly blinded him and his wife both for several seconds.
