Out of a 4" barrel at 921fps the Rem. FBI load will work.
A test on Luck Gunner had the 2" barrel at only 802fps.
only one out of five started to expand and the average for five was only .40" dia. from a .38 dia. bullet !!
For SD use there are better loads to trust your life on.
Thanks for the info guys. I prefer the Remington load for my model 10. I've been using speer gold dots in my 442/642 because they have less recoil and perform well in the short barrels from the reviews I've seen. I'm sure they'd do well in the model 10 also,but as expected the 158 grain bullets seem to hit right at point of aim.
One reason that the Remington/Winchester FBI load has a good street record, is that it was a lot better than the old 1867 Round Nose load that out of a 4" barrel did around 755fps and had a ME of only 200..... that was called "The Widow maker".
Even though it took until 1922 for Winchester to come out with the FBI load, with 890fps out of a four inch barrel and ME at 278, it had to be better with the new SWC/HP design, if it expanded or not.
An added 135fps will help any 38 Special bullet.
I gave you a link to the Remington FBI Load in Post #3 and they are in stock.
I use the +P version myself and while stout out of a 2" Chief's, there is no better SD round you could use (out of a 2" Chief's - IMO) if you can deal with the recoil. Many do go to the standard velocity that is much less violent and still packs more punch than the Remington or Winchester +P version.
The standard pressure Buffalo Bore is my preferred version of the FBI load, but I'd be ok with the Remington +P version.
I once fired 5 rounds of the BB +P FBI load through my 642. My first thought: "Well, I'm never doing THAT again!" Fortunately, I still had a couple of steel K-frames at the time so the remaining rounds didn't go to waste. But the standard pressure BB FBI load is controllable in my 642, at least for me. If I run out of Speer SB-GDHP, I still have a box of BB to tide me over.
