When the smoke settles.....................

you might find that your weapon gets better accuracy with that 125 gr JHP bullet only going around 1250fps for target work.

I can get my 686 6" over 1500fps with medium fast to medium burning powders. I save my 2400 for the heavier 158 gr bullets.

For SD loads I prefer 140 gr bullets or heavier, in case of heavy clothing.
Not saying that lighter bullets will not work, though.
