Wadcutter data?

[Randy1911]

I have a hard time finding data for 148 gr. DEWC. Most of the data I can find is for 148 gr. HBWC. Can I use this data with regular wadcutters? Does the hollow base make a difference?

I also had a hard time finding data, so I worked up a small load to see what would happen.

2.7 gr unique under a 148 DEWC with the bullet seated almost flush...just a little lip. (on my bullets there are 2 lube grooves and 2 grooves) I just set them to the groove.

The shoot AWESOME in my 686 6 in. barrel. Almost no recoil, really accurate.

I'm going to try some red dot next, probably 3.0 gr since I hear it's a little cleaner than unique. (I still see some unburned powder in the barrel)

Well, you need to get yourself a Lyman #49 Manual. Or a Speer Manual.

And yes, the data is much different if you get past mild target loads.

You cannot load HBWC hot because of skirt seperation in the forcing cone.

But you can load hard-cast DEWC to near magnum velocity if thats what you want.

DEWC and HBWC

Many load manuals listings for HBWC are not pressure limited but are lower due to the tendency for the Hollow base to distort when it leaves the barrel under high a pressure.
Most WC shooters are looking for accuracy not power.
I used to load a lot of DEWC using data for a 150 grain SWC for a starting point. Be careful of the increased seating depth and bearing area raising pressures.

rcmodel,

I have the Lyman #47 and #48. I guess it's time to get the latest edition. I am only wanting light target loads.

Well, Lyman #47 has solid base WC data on page 388.

It is listed under Mold #358495 - 141 grain (Linotype)
No, it is not a DE design, but is the same thing for all practical purposes.

If it was cast of softer lead, and you add in the bullet lube, it would weigh 148 grains.
