I won’t get hipster kudos because i would be shooting a deer and that would just be too distressing for hipsters.

You could shoot them ironically with a vegetarian sausage

A 120gn (8g) slug would have to be travelling roughly 600fps at 100m to deliver 1350 joules at that range.

Wombat · October 2, 2018, 10:16am

That sounds achievable.

Gwion · October 2, 2018, 10:18am

It does but i wouldn’t know because i know nothing about loading for shot guns!

Oldbloke · October 2, 2018, 11:06am

1350 joules = 995.7 foot pound.

I just used a calculator on my mobile.

Oldbloke · October 2, 2018, 11:10am

If you know the bc, weight and speed should be able to plug the numbers into a on line ballistic calculator.

GUN-DMC · October 2, 2018, 11:14am

Ballistic coefficiency is not a term I’ve seen used in conjunction with any shotgun slug before, lol. Slugs are more like throwing bricks than any kind of well designed rifle bullet.

Gwion · October 2, 2018, 11:16am

A round nosed slug would translate roughly as a G1 BC, i think.

Gwion · October 2, 2018, 11:17am

Could you use a 45 long colt bullet as a 410 slug?

GUN-DMC · October 2, 2018, 11:26am

without a rifled barrel to stabilise it, it would not be very acurate. with a smooth bore you need a nose heavy projectile to get the drag stabilisation, you could experiment with gluing felt wads to the back to get the drag?

no Worries I have a couple of boxes of factory stuff. i will bring the string. @Oldbloke is that going to be the tree we tie the gun to?

Bent_arrow · October 2, 2018, 12:11pm

So I totally get the idea of using brass cases instead of plastic. What are the options for replacing the wad, that bothers me more than the case because at least I can put the fired case in my pocket and reuse it a few times. The wad though ends up somewhere in the grass/dirt/rocks and is a one use only option.

Cheers

Seems felt and cork are commonly used.

GUN-DMC · October 2, 2018, 12:26pm

and even just cardboard box and uht milk carton

Bent_arrow · October 2, 2018, 12:34pm

I need some more guidance here… One of the “how to” that you guys have been banging out lately would be awesome…

GUN-DMC · October 2, 2018, 12:44pm

Probably won’t be till next week, but I’ll take some pic’s and write something up.

Bent_arrow · October 2, 2018, 2:22pm

That would be great. I’d really love to be passing hand loaded .410 in brass cases to my boy rather than blasting bits of plastic all across the paddock. The next thing would of course be I’d have to step up and run brass cases through my Rossi 12g coach gun

Gwion · October 3, 2018, 9:22am

Here it is!
From memory it is Belgian but I’ll take it apart for pcs when i pick it up.
