2.5" 410 Slug Work Up AS-MOLDS, 132gn Foster

[bullet225ho]

Folks,

Just got back from the farm and thought I'd share some info about a new slug I'm putting together. It's from an AS-Molds foster type mold. I'm getting right at 132-133gn with sheet lead and dropping in water.

I have put together 2 different variants of this slug. one is with a spacer and a roll crimp and the other is directly on the wad with fold crimp. I get higher velocity with the roll crimp version. Accuracy seems about the same.

Starting with the slug itself. mine are coming in at 132.5 gn.


I'm starting with previously fired Cheddite 2.5" shells (actually think this is the 3rd or 4th firing of these) Cheddite CX2000 primer.

Powder is Alliant 410. load data was derived from Advantages manual.

Wad is Gualandi mini container or BPI SG410. I'm trimming off the shot cup on these and placing a nitro card on top for roll crimped loads. For folded loads I'm placing slug directly on top of wad.

Uncut wad next to load configuration


So, Primed hull, Powder, then wad and slug.


Off to crimper station on my MEC600 or roll crimper on drill press.


Today I shot just the fold crimp version. Velocity was:

1576
1511
1568
1687
1552
1668
1594


AVG: 1593

I shot at a couple different targets. Here's a shot of one. No sign of tumbling or keyholing. This was from 30yds.
Gun was Tristar Cobra II .410 pump with 28" barrel. Imp Cyl choke tube. Bead sight.


Not sure where to go with it from here. May go lighter on the powder. May try a load with Lil-Gun and see what it likes.

Wheeee! Great stuff - I got the Lyman-style recently from Svarog recently. Still groping towards a load using L'il Gun or H110

Really like seeing all this work done with slugs. Only thing that’s bothering me is my 410’s are all fixed full choke H&R’s

Thanks for posting this. I've had good luck with round balls in my cylinder-bore .410 garden gun, this target at 25 yards. Cartridges are .44-40 Game Getter .425" round ball assembled in 40mm Starline 5 in 1 blank cases with 5 grains of Bullseye, fired in 2-inch .410 chamber from pre-WW1 H&R Garden Gun with .420" full cylinder bore:

Watching!!

Ya should measure the choke. While
Many are about .390 NOT ALL!!

My two H&R are labeled FULL ONE IS .401 the second is .396. I have a Savage bolt thats .386 and two chopped that are .409 & .411. Remember "choke" is a relationship from bore. NOT a stand alone number.

.390's shoot well for me in all I have tried. A foster slug easily squeezes down for chokes. But a ball esp a hard ball DOSENT and can split barrels!

Good stuff, nice work!
