Problem: Trail Boss in .38 Special

[Bimmer]

Those are some light loads, but if they work, that's all that counts...

Yep...

~600fps with the 148g is close to the "standard" load I grew up with. I want to say min was about 650-700.

I personally consider those to be close to no recoil, in the 22lr range when shot in in a 4"revolver.

The 148s at 500-600fps were snappy... Not harsh, but not .22lr level, either.

I think part of the issue is I'm shooting 3" LCRx's, and empty they only weigh <16oz (!), so felt recoil is a lot more than it would be when shooting than steel 4" revolver.

If you go lower you will want to look out for squibs.

Use a penlight to look down into the cases in the loading block after your powder is loaded. You can visually compare powder levels even if well below the case mouth.

Loading block? What's that... I'm kidding of course, but I use a Dillon.

Knock wood, I had never had a squib load in 25 years of reloading, after tens of thousands of rounds. I understand the danger of getting a bullet stuck in the barrel with such light loads, but I also expect that danger is reduced with such a short barrel...

FWIW, I had the 95s leaving the barrel every time, at down to 250fps.
