38SP 148gr WC

[cardonasharp]

I would like some help. I have never reloaded for WC. I am trying to find out how you load this type of cast bullet. I would like to use trail boss gunpowder. I am using RCBS mold 38wc 148Gr. I want to reload for a revolver using 38Sp brass.

cas, Since you'll need to roll crimp those WC's once they're seated, make sure your empty brass is the same length: Measure and trim them, reserving those which are too short for practice. As for the RCBS 148 gr. WC, look for the crimping groove toward the nose. You'll want to seat them as close to that groove as possible while still allowing a roll crimp to be formed. Btw, I set up my seating die so that it seats only (refer to the instructions that came with your die set), preferring to crimp as a second operation (seater stem is raised as far as it will go and die is turned clockwise 1/2 to 1 turn and secured). If your WC is the one with a flat button nose, you may find it is significantly more accurate if it is seated (and crimped) backwards; i.e., with the base forward/button nose in the case. Btw, I size them to .358" for a S & W Mod. 10, but .359" for my Ruger Black Hawk & Dan Wesson revolvers. Sorry I can't help you with loading data for Trail Boss powder (check with its manufacturer), but the standard load .38spl. WC load.is 2.7 - 2.8 grs. Bullseye.

Howdy!

If it is like mine, I'm still working up a load for it in Trail Boss . . . check this link for recent pictures of mine http://castb

So when i seat them the second to last grove I should crimp them there. The cast bullet will stick out of the case 1 grove correct.

Remember you can not compress Trail Boss . . .

My WC are flat on both ends. Can I seat them flush with the brass. or leave one grove out.

[Three-Fifty-Seven]

...in?

[cardonasharp]

Thanks for the help. I will load to 3.0gr trailboss and seat flush of the brass. Should I use the 38sp or the 357 brass.

I load mine the same way cardonasharp does with from 3.0- 3.5 grains of trail boss.

I have been reloading for about a year. I am using a SW model 620 357 magnum 4 IN barrel. I am using a Dillon 550 press. I like to use the trail boss if you over load the casing it will spill out. I am using 38sp case trim to 1.145 as per speer #14 manual page 874.

Correction -

Here is their pdf http://www.hodgdon.com/PDF/Trail-Boss-data.pdf

[runfiverun]

y'all need to remember that 38 cases are tapered and that ones like the federal wad cutter target cases are different and have straight sides.
seating a wadcutter to full depth might just be squeezing the base of the boolit and also explains why a lot of guys cannot duplicate factory target ammo accuracy.
if your boolit has a crimp groove seat to it if not i'd look the cases over and adjust accordingly.

[cardonasharp]

I do measure my powder. When I started to reload Joe ask me to buy trail boss. He suggest that powder just in case I accidentally loaded it twice. Now that I have loaded a few thousand rounds. I am getting use to my press and so forth. Now to your reply. I will work the load at 2.5 to max of 3.0 to see how it does. Is this a good Idea. I also reload for 45acp,40sw and 223 all cast accept the 223. I am a newbie.

[Three-Fifty-Seven]

Yes, ,

[cardonasharp]

I went to shot the reloads I made and the result are in.

I loaded 24 rounds of cast bullet made from wheel weights.

RCBS mold 38 148 gr WC

1. 8 rounds @ 3.0Gr of trail boss good
2. 8 rounds @ 3.5gr of trail boss good
3. 8 rounds @ 4.2gr of trail boss better and smaller groups

distance to target was 15 yards at a 5 inch round stick on.

Test revolver was a SW model 620 4 inch barrel with adjustable sights.
My revolver prefers the trail boss @ 4.2gr. When I change the amount of grains my shot are not that tight.

Just a couple of questions, don't mean to hijack the thread.

1. Why is it necessary to roll crimp wadcutters?

2. Why would obduration of a hollow-base wadcutter damage a gun? (Speer manual)

Hope that S & W 620 works out for you. Is that the one with the two-piece barrel (insert)?

Again, hope I didn't hijack the thread. :coffeecom

No my gun did not go in two pieces.
It is to keep the bullet from being pulled out from the recoil.

[scrapcan]

ON the hollow base wadcutters you can push them too hard and it will seperate the base at the forcing cone. You can imagin what happens when you send the next one down the pipe with a nice lead washer in the forcing cone of the barrel.

How deep did you end up seating them?

Glad you found something that worked!

That is a nice looking boolit design. What is the maker of that mold

It is the RCBS 38-148-WC…

It is the first cast boolit I started casting and I have used it a good many times…

I have perfected my casting techniques since that one was cast and I am now getting the base a bit less rounded…

A good shooter for sure…

IMR's reloaders guide suggests 2.7 up to 4.2 grains of Trail Boss for a slightly heavier 158 grain bullet.

It's not. I load on a Dillon. Just enough taper crimp to close the bell from the
powder charging stage.


2. Why would obduration of a hollow-base wadcutter damage a gun? (Speer
manual)

It won't. I would keep them to not much above target velocities. The skirt may be damaged. There are those who seat them hollow base out for hunting or self defense loads

Yes, but what is the COL?

Fortunately CS has a 357 mag, or he might have a pressure problem. Seating deeper with the same powder gives more pressure . . .

[cardonasharp]

OK I have been getting a lot of PM about my load. Every one is saying that I am creating to much pressure because I am compressing my powder. I measured all of my reloading components.
1. bullet 0.546
2. case inside 0.983
3. case fill with powder 0.463

case depth 0.983
bullet 0.546
----------
0.437 space that is available

loaded case of 4.2 trail boss is 0.463

0.463 loaded
0.437 available
----------
0.026 minus bullet pushing on powder
