Building Muzzleloader

[treillw]

Kicking around building an inline muzzleloader with a Brux prefit barrel from Arrowhead Rifles. Suggestions on components to go along with it? Can use any old remington 700 action I guess. Good sources? Would need to come up with a stock that can accept the large diameter barrel - imagine I'd have to order something.

You'll be better off with a 700ml action. The bolt is different and the lugs are different.

I've built with Brux barrels from him but not a prefit. I built off ML specific actions like the Mesa ML and Defiance Outcast. I'd prefer one of those over a std Rem 700. The shellholder boltface is worth the upgrade. Ask Luke if he'll do a prefit for one of those. I know he has the dimensions because he's sent me his tenon drawings. Modules come in both std and mag so order to fit your boltface. I'm not aware of either being better than the other. Barrel channel shanks are long (5"+) so yes inletting on a regular Rem action/barrel cut won't fit. No you can't shorten the shank up much. For a cheap quick and dirty drop in a Bravo will work. Any chassis with a straight channel should work.

Edit: It looks like he's using a barrel nut and a reduced diameter shank so maybe a std barrel inlet works???

Edit: In the video he states "you can't run them as hard as our custom builds". I'm sure that is directly related to the reduced shank diameter.

I bought a prefit from arrowhead and used a remington 700 action I had laying around. I used a grayboe Phoenix stock. It works great, no complaints. I shoot arrowhead nsr 275 grain bullets.

If he uses modules than no, he wouldn’t be better off.

 

[Pickettpuncher]

You can use a savage action and get a prefit as well. My barrel is a pacnor. Pushes a 275 around 2800fps. I would suggest looking at a sizing die and ditching the sabots.

I've messed with both and would prefer the shellholder boltface. The std works but the shellholder is better under pressure, pressure while attempting to reload in the field that is.

As long as you never want to hunt in the nw the std face is great.

Why's that?

I'd assume it's in regards to a couple of rules up there?

Oregon: Hunters shall use only flint or percussion caps as a source of ignition.
Washington: Ignition is to be wheel lock, matchlock, flintlock, or percussion. Primers designed to be used in modern cartridges are legal.

This is one of the biggest problems with modern bolt and inline muzzleloaders. The regulation of these guns by state fish and wildlife agencies varies widely between states and even within state. If you set up a gun for your state, you may not be able to use it in others and your own state may change what’s allowed from year to year. NM just changed their regs about two years ago, banning the use of magnified optics on muzzleloaders.

The other problem is these modern muzzleloaders just recoil like a beast, are less than fun to shoot, and … egads, man… you have to clean them. I haven’t cleaned a long-gun since I sold my last muzzleloader.

Handmade flintlock or bust….

I've heard a few people say that it is easy to build your own inline. Where does one obtain the information to learn how to?

Parts I'm considering:
Defiance Outcast (or cheaper alternative - I wouldn't imagine the action to be terribly important for an inline)
Arrowhead Brux prefit (or could get a smith to cut the threads)
McMillan Game Warden

Can you buy all this with a prefit barrel and cobble it together in your basement?? After spending $3300 on parts, I'd probably rather have somebody who knows what they are doing put it together. Do you have to bed the action into the stock?

Thanks!

It’s a lot easier to build an “inline”. Get a single shot 45-70 break action and have it sent to get a breach plug. You’ll need a few other things like a ramrod but they work fine.


You’ll want someone who can headspace the rifle correctly. If you use a nut setup like savage you can do that yourself if you know how. Bedding the action would be up to you, but I would. You can spend as much as you want on one or got with a 45-70 conversion for around $1k

 

[PistolPete]

I know this is getting off track, but for the same cost as a CVA 45-70 conversion, you can buy a Woodman Arms muzzleloader that can take smokeless, weighs 5.5 lbs, is made from completely nitrided stainless steel, made in NH, and is beautifully fit and finished. I just picked mine up this summer and it's a masterpiece. They don't charge near enough, so they have a long waiting list though...

Have a look at Hankins custom rifles. He has a system of installing a custom breech plug in a CVA 45/70. I had one built this spring and couldn’t be happier. I sent him the barrel, he did the work, I got his breech plug and modules which shoot large rifle magnum primers, a bullet sizer and collapsible ram rod. With the rifle and all his work I was slightly over $1k. Im shooting 275gr Fury’s at 2560fps. It shoots 5 in easily under 1.25”. Couldn’t be happier.

call shultz precision and speak to jd shultz.either him or jon beanland.thank me later,one hole muzzleloaders.jon for arrowhead ignition or jd for hankins ignition.i can assure you you will be extremely happy with either.jd built me a 45 cal one hole muzzleloader.jon is my go to rifle builder now and there are a few excellent builders but jon gets all my new builds.

Were you able to do this diy or did it require a gunsmith?

@treillw did you pursue this project?

I'm going to get a smith to do it. Threading barrel for defiance action, threading brake onto barrel, opening up brake internal diameter, bedding stock.... Some I can't do, rest I'd rather just pay somebody to do right instead of fussing with it and driving myself crazy.
