Thanks CoMF, I started a similar post but decided to just let it go. So far, other then the information I received from Speer that the SB is intended for 2" barrels and would be OK in a 4" but nothing longer, is the only information in this thread that I can substantiate. Everything else is conjecture or opinion. I have not found anything with testing to back it up that shows the 135 SB will function as advertised in a 5" barrel. I also have not found anything negative about the 125 gr bullet unless you try to shoot through a barrier which might even be an advantage in a HD situation. It's been an interesting thread with a lot of opinions expressed but I still think I'll use the 125 in the 5" and the SB in my snubs as per Speer's recommendation.
