Mausingfield or defiance ?

[bulldog911]

Looking for input if you have ran them both. I've only ran a mausingfield and didnt have any issues. Was incredibly smooth. I have not used a defiance yet. What are the pros and cons do you think? I plan on a LA build in 300wm, carbon barrel, carbon stock. Going to use for elk and general steel. Side note, planning on running a 22" barrel due to only shooting with my can on. Is this wise for a 300wm? Or should I go longer?
Thanks

Can't comment on the actions, but my 24" 300 WM runs the 215 Hybrids at 2800 fps with a mild load and it smashes elk .

That's what my last 300wm was. 24" with 215 but I think mine was pushing hotter. Thoes 215s are devastating on elk. Like mini grenades once they go through skin.

Mausingfield 10 times out of 10.

Crf, huge extractor-- if you're going magnum I would go MF for this alone--, 4340 chromo at 50 hrc it's the stronger of the two, keyed rail (can change incline if you want, or get extended rails) holds tight even without the screws in you have to knock it off with a rubber mallet. Interchangeable bolt heads if you ever want to go standard bolt face. Get a barloc and a Savage prefit proof and you can swap between 300wm, 30-06, etc.. if you want. And one of the biggest things is the parts are sized to work. They shrug off dust, dirt, etc .. don't gall, and keep chugging. You can argue crf vs push feed, and which is smoother to run, etc etc... but there's no debating it's a more durable action.

Both will work. A Ruger American will work, but the MF is a better action in the land of diminishing returns IMO.

I'm getting ready to buy a couple of long mag bolt face actions and I've done a little research in the past week or two.

A Defiance action is available with a large claw style extractor. It is also available with a shroud safety. A Defiance Rebel action is available in 4340 Chromoly, I actually have a short one. I don't know the heat treatment specs.

The Rebels have pinned rails in 0,10, 20, 30, 40, 50, 60 MOA inclines. The Deviants, depending on which one you choose, are available with integral rail mounts from 0-30 MOA in 10 MOA increments.

A complete replacement bolt for a push feed Defiance is only $100 more than a Mausingfield bolt head and you can get Bug Nuts for them if you want.

Both are great and have their respective strengths.
You'll have a fine tool for the job on either path.

I would personally go with a Mausingfield every time because of the reasons Ledzep articulated. When it comes to a hunting rifle, I prize reliability above everything else.

ARC > All the things

Where can you buy a Mausingfield action?

 

[PistoleroJesse]

Defiance has better light weight options in the short term if that is a concern.

I think ARC is doing a MF hunting action, but I haven't see a lot about it.

 

[Jeffd]

Have several of both! MF is my go to!

I looked at the websites of all those places and didn't see any. Do they have some not shown?

For LRI, SAC and PVA you will likely need to call to discuss your needs and options.

ARC above all. Either the mausingfield or nucleus. Either will fill your needs and more.
