.410 slug loads.

[Philly]

So the pic is a dummy just for clarification. So, anyone have any good loads for a heavy slug for whitetail? I was thinking of building a .410 bolt action with a .416 rifled barrel for short range whitetail in Idaho. Anyone have any ideas or info or words of wisdom? Thanks.

Combining a projectile of that weight and bearing surface with a shotgun shell does not sound like a prudent idea.

I think it’s Hmms or something like that that loads some heavier slugs. But why not build something that’s a little heavier than what’s on the market and a rifled barrel?

 

[mike mccormick]

That sounds like an exceptionally bad idea, depending on the base action to be used.

 

[Philly]

Like a 700 magnum action. (Or maybe a savage) Same bolt face. And a rifled barrel.

 

[joshb]

I think your pressures will rise over what the shotgun shell can take because of the rifled barrel. Just buy a nice 20 gauge slug gun.

That’s the thing, I want to try something out and load a heavier bullet. I’ll let everyone know of my conclusions.

Well,...I wonder why this has not been tried before? oh wait...it has - but the guy that did it used brass cases and better powders. Called it the 45/70.

well, clearly before short range weapons and shoshell. I’m interested in In real info, not opinions. Has anyone loaded some heavy loads for .410? .416 loads?

 

[Coyotefurharvester]

Keep it under 16 pounds.

 

[mike mccormick]

Shotshell casings are a definite non starter. Maybe something based on the 405 winchester case?

Post your test fire video on youtube.

Seriously - shotshell cases are not the way to go. This guy has some loads that are, well, light. Other than the sectional density, they duplicate 357 magnum- ish loads ( 125g at 1300fps) but at a pressure that is safe for shotshells (10-12,00psi). The case will still fail in a bolt action.

But to keep safe, the load with a heavier bullet, must be so light/slow as to be a bit useless, otherwise the case will fracture and, at best, you will have a face full of hot gas. Otherwise, you could be wounding an animal.

I have experience with the 458x2, which uses 7mm Mag brass shortened, as a subsonic round and the 450 Hornday, both for hunting in bush. They both work. As does the smaller 450 Bushmaster, and a load of other large diameter rifle and pistol game calibers. You could certainly experiment with heavier bullets in the 450 Hornady, but you may have to increase the twist to compensate for the length of the bullet and the slower speed. And, by the way, a subsonic 400 grain bullet in the 458x2 generates more pressure that a shotshell could handle - some loads would flatten primers.

Getting 416 projectiles to provide adequate terminal performance to cleanly take down deer might be a problem.
Yet if you still want to go down the road of shooting projectiles from a 410 case it appears using 444 Marlin brass is the way to go however projectile type with a ~2" case should be considered so to not have issues at the forcing cone with so much leade from short brass but of course this can be addressed with a custom chamber.
How hard you can push 444 brass should also be considered along with the weight of projectile you intend to use when 9/16 ounce loads (~250gr) are the normal max for a 410.

Then again if you just want to put big diameter holes in deer at close range an off the shelf 44 Mag or 444 rifle might be the simplest solution.

I appreciate your info. I’m wanting to this for a couple reasons. I’d like to build one on a bolt action and the second reason is that Idaho law won’t allow rifles for short range season. I’ve seen plenty of 12 and 20 ga shotguns with rifled barrels but haven’t seen many .410. Btw, the pic I posted is an exaggerated shell. I’m looking for much smaller. That is a custom made bullet for a 408 cheytec.

What sort of ranges are involved ?
Maybe you could consider 410 rifled slugs ?
Federal and Winchester do factory slug loads approaching 1800fps.

There's also .41 cast slugs if you must go down a rifled barrel solution.
Google: .41 cast bullets

I know a gunsmith who did something similar but he used brass 410 shotshells. Had to be actual shotshells because it was a shotgun only zone at the time. No idea what bullets, ballistics, and velocity. Still limited by case strength.

Would you care to enlighten me on the parameters of short range season in Idaho please. I haven't a clue about what that entails. I do admit to having no information for you regarding your quest to use the .410 shotgun as a rifle. Back 50 years ago I heard about a guy that would remove the shot from a .410 shell and launch arrows from it. Even that sounded a bit risky to me

Short range weapon is archery, muzzle loader, shotgun and handgun using cartridges originally developed for a handgun.
