For some shorter range action shooting I am looking for some load ideas.

I have a few manuals with slug loads in it but they are all full power loads.

What I have on hand
Hull: Remington Gun Club (one piece tapered)
Wads: quite a selection
Powder in this range: Win 231, SR-4756 and HS-6
Primers: winchester and cheddite

Plan on shooting it out of a Mossberg 590.

Hope someone here has some experience with the 525 slug in a slower load and willing to chime in.

thx, Bert

To add: these are my results out of a fully rifled 20" barrel on a Rem 870.

Thanks!
Did you make the graph yourself or is it part of a balistic app or something?
I'll convert it to grains and fps to see how it compares to the full load data in my manuals.

Do you think there is a lot of difference out of a smooth bore compared to a rifled barrel?
 
You are welcome. I made the graph using MS Excel. I have never tried the slug out of a smooth bore as I suspect accuracy would be terrible. In terms of velocity my wild guess is it would be pretty similiar, as a plastic wad doesn't have much drag against the slow, shallow rifling.

For a reduced load, I would load the faster powder, like 231 or 700X. I would work in the 15 to 18 gr range.

Thanks, I have a good supply of the D700 Dominion powder. Any experience in 700x in terms of grains and velocity with this slug?

might have a bit of 231 as well. sometimes being a hoarder isn't that bad lol.

Any advice on what is better; 8 point crimp or roll crimp
 
Please keep us updated on your progress bertn. I have a bunch of those slugs that I cast about 25 years ago. I have no need for mule kickers! Thx
 
ok, update on the homework done so far.

Sorted out my wads and only 3 had a good fit, the rest were too tight at the bottom making the petals flare out at the top.

I think I am going to use the brown one, federal 12S4 since it is build a bit firmer than the others.
Depending on the height I need in the hull either cut the petals or add fiber/nitro disc under the slug.

I have win, rem and fed primers so have some choice there.

Weighed the slugs and they are actually in the 518 grain range. Plan on filling the back with hot glue to prevent the wad from cutting into the slug and get stuck to it.
That will add some weight and if I'm adding the fiber disc that will add as well.

All together the weight will be close to a 1 1/4 shot load (= roughly 547 grains) so looked up some loads on imr and hodgdon website.

published load with components that i have is:
26.5 gr SR4756, fed primer, 12S4 wad @ 1230 ft/sec.

I'll load a few like this and see how they shoot and kick.
Battlerifle made me rethink my choice of shotgun and have decided to use a mossberg 835 with 24" rifled barrel.
The buttpad is a bit stiff on this one so maybe I'll do a flipflop pad modification to it lol.

I think I'll also try to tame this a bit to get around 1000 fps.
Ganderite (or someone else) do you have an idea how many grains less I should start with?

thx again for tapping into the collective wisdom here :)

I’m liking where you are going. I’d like the 1,000 FPS as well as I’m mainly looking for short range 3 gun loads. Have many of the components you have listed. Also have the 7/8 Lee mould as well.
 
I have use the Lyman slug
Data from the Lyman shot gun book

rem 870 ic one day I shot 25 slugs out of it and was not sore the next day

good enough to break clays lying on the berm at 50yds

I used to find the win AA Hulls in a different colour ( Grey ) and load them

For me a quick ID
red= shot
grey= slug

Casting your own

it used to cost me $6 for a box of 25
Plus my time
 
I have the mould but ran into a box of 100 pcs made by R&R bullets at a Woodstock gunshow once for only 20 or 25 bucks and could not resist :)
 
You can make good, cheap reduced recoil slug ammo by buying cheap target trap or skeet ammo. This is 3 dram ammo. Challenger also makes a 2 3/4 dram load. Very mild.

Cut the crimp out, leaving the folded edge in place. You can use a box cutter or a hole drill.

I use a 16mm hole drill. The bit looks like a little socket, with rough stuff embedded in the edge.

Cut out the pie-crimp, dump the powder, and drop in the big air gun style pellet slug. It will insert easily into the wad, except for the fat ring at the top of the slug. I install all the slugs, and then go along the line of ammo, tapping each slug with the round head of a ball peen hammer. This pops the slug below the folded mouth of the case, and the result is a good slug load.

Interesting! Brings up more questions;
How do you seal the case, do you roll crimp it after or leave it like it is in the picture?
If leaving it like this would you get enough pressure build up?
What is the accuracy/grouping of this "Mexican match" slug?

Look closely. The roll crimp is still there. I cut out the crimp on the inside of the case mouth, leaving the roll crimp in place. That it why it takes a little tap pf the hammer to pop that slug into place.

pressure is consistent and accuracy is good.

Ah, yes I see what you mean.

Since it is more like folded in instead of roll crimped will the ridge actually fold open or will the wad slug combo squeeze by, pushing the ridge aside?

Worth a try since I have enough 1 1/8 oz 3 dram shells here.

What group size is to be expected with this at 50 or 100 yards?

thx

The rolled over edge of the crimp does not open. You don't want it to. It is holding the wad under pressure that should not be disturbed. The slug will drop into the was easily, util the fat leading edge hits the mouth of the case. Then you hit the center of the slug with something to pop it into place. I use a ball peen hammer.

Accuracy is good enough for general plinking and practice at 25 yards. I did not try it much at 50, but I recall it hitting ok.

This is an easy and cheap way to make slugs if you don't have shot shell loading gear.
