148 grain HBWC (HOLLOW BASED WAD CUTTERS) are loaded lighter,
or you'll risk blowing the skirt off and it remaining inside the barrel.

They are SWEDGED BULLETS made from softer alloy.

NOT A GOOD THING FOR FOLLOW UP SHOTS!

DEWC are usually a CASTING from a harder alloy and can be pushed harder.

DEWC'S look like a little SOUP CAN, (no hollow base).

Wadcutters are mostly used for target work, why push so hard?

PENN BULLETS has 38 Special DEWC rated at up 900 feet per second,
target charge of 2.7 grains of Bullseye is the STANDARD TARGET LOADING IN A 38 SPECIAL CASE.

He has Target 158 grain SEMI-WADCUTTERS rated to 950 feet per second,

The 158 grain Semi-Wadcutters in MATCH ALLOY are rated to 1600 feet per second.
