Gold Amber Rectangle Cuisine Dish

Looking for a known load for these. Figuring +P .38 Special is the way to load these as Underwood uses these style bullets.
Lehigh published these loads for the powders I own: 5.5 Unique 1,015 fps, 5.4 Bullseye 970 fps, 5.9 Universal 1,020 fps.
To be tested in a 4.2" GP100, used if needed, in a 3" 60-15, and a 2" 637.

What grain are they? Loaded +p should be good. Can't help with a proven load though.

Normally whe one load is listed, it is max, and shoud be reduced 10%. "Reloading 101"...

Started on sizing, neck belling, and priming 50 new Sig 38spl cases for these beasts. And yes, start lower. I've had good luck with Hornady 125 gr JHP's and a "warm" load of 5.8gr of Universal, standard Federal primer. I think I'll use that for my first 50 Lehigh Xtreme Defense. The max is 5.9gr. Got 100 more Lehigh bullets coming in the mail. I test in my GP100, and would never load a ~1,000fps +P round in any of my "antiques".

Lehigh's loads show 5.9gr with Universal, which is my chosen powder for this new load. 10% puts the starting load below the 5.5gr starting load on their chart. I intend on being conservative, but probably "warm". Will work up to 5.8 of Universal. Saving my Unique for incoming 44 Keith bullets.
