Reloading shotgun slugs

Postby Shooter45 » 04 Nov 2015, 17:45

Anyone else load 12ga slugs?
I am just getting started.
Casting/Shooting 7/8 oz lee slugs .. 1150 fps
I think that comes out to 1124 ft lbs of energy. (I might have energy wrong)
It's new for me to do and having fun with it.

If it goes bang or boom, I like it.

Never tried, but I have been wanting to. Keep it up!

I have the 12 GA. LEE Key Drive Slug Mould in 1 oz.

I am not sure I have ever cast up any? Be interesting to hear how you like them. The 12 GA. shotgun is BAD MEDICINE at close range, slug or scatter.

PS:

Looks like to me you are spot on!

The energy in ft-lbf is:

E = (M x V²) ÷ K

(That is from Kinetic Energy = 1/2mv^2 put into proper units)

Where "K" is derived via taking 32.1739 as "g"

So, taking `383 grains for 7/8 oz. slug's mass, and a velocity of 1150 ft/sec:

E = [383 grains x (1150 ft.sec)^2]/ 450435

Yields 1124.5074206 ft-lbf

Looks like to me you are spot on!

I shoot the Brenneke SFMBP slug, but, of course, DESPISE, buying loaded ammo, and especially despise NOT casting them myself. :)

2 3/4" shell
1 3/8 oz. slug
1650 fps.
"Muzzle energy: 3545 ft/lbs "

The 1650 is correct as I chrono'ed them in 85 degree weather and that number was spot on.

As you say,a shotgun up close is a terrible weapon.Likely the single most useful and versatile gun in the world is a short barrel pump 12 ga with a good set of sights.I have a .730"round ball mold and have loaded a few of those in 12 ga cases with 80 gr of 3f with much better results than I expected.

I have all kinds of slug and ball molds but just never got them right. I don't hunt with them anymore but I have a Hastings rifled barrel on my 870 for fun. I can't even equal the WW foster slug accuracy.
It has shown me it is always the wads causing the problem, slugs in a shot cup never worked and HB slugs would have the wad driven into the base. I don't know how WW did it. Never got the RB to work either.
I have bought some slug kits like the Hammer Head with strong sabot's that are deadly to 100 yards or more but hate to spend money.
Years ago in Ohio I tested all brands and thought I was doing good with the Brenneke at 50 yards, one hole I could see but that was it, all the rest missed the whole target. WW would hold a tea cup. Out of an Ithaca 37 the WW would hit targets at 100 yards with just the Raybar sight and smooth bore.
This is an area I fail at.
