400 Whelan or 411 Hawk

[nitro-express]

Speaking of 350RM, I saw one today at a gun show in a 600 Mohawk. A bit lively for me.

I concur, mine is a 700 Classic, tamer but still not tame. Necked up to 400, it would be a real mans caliber. I've fired cast in the 416 Rem Mag, seemed just as intense a full power 30-06 load. IMHO cast bullets are the way to enjoy the bigger calibers to keep in practice.

On the list for me is working out cast loads for the 350 RM.

I'm learning a lot about the 40 cal rifles with this thread.
Keep the info coming

Given the current supply problems, I'd look into a good bullets source before building.

I recall doing some research on a 400 Whelen because it intrigued me. But after reading about head space problem because of the shoulder I gave up on it.
A good man on a good lathe making tight tolerances may solve this issue now a days.
I mean they can headspace rimless stait wall cartridges now.

Good luck, would be a great hunting rifle for serious game.

A major point to this is to use the common 30-06 brass, but a solution to the headspace problem (if indeed there is one), could be to use 9.3X62 brass which is slightly larger in diameter and capacity. 9.3-400X62

In fact if 9.3X62 brass was scarce, you could use 30-06 brass which upon firing would fill out the slightly larger chamber. Many people use 30-06 brass for their 9.3X62, myself included, and have posted the results here on CGN.

I think you just described the 411 hawk-scoville

Aww shucks - after all that work "inventing" it, I guess I can't name it after myself.

400 Andy sounds better anyways

But what would I then name the other 50 "Vanity" cartridges I can "design" in the next hour? I'll "improve" existing cartridges a couple of thou here, couple of degrees there and I'll have them optimized for say a 23.6" barrel at 18 Celsius.

Had to look them up...

I satisfied my .40 cal. itch with these three: .40-60 Maynard, (brass is easily made from .30-40 Krag or .303 BR.) .40-65 Win and .40-70 Sharps Straight. (Cases are made from .405 Win brass) All are gentle to shoot, easy to load and are accurate with the 400 gr Snover cast bullet. As a bonus, all can be loaded with BP!
PS: If it can't be killed with either of these cartridges........it's too tough to eat!!!!

There is a CIP "certified" 400 Whelen in Europe, called 10.4x62 (or 10.4x62 Impala). Factory cases used to be available, but I can't find much info on it.
This cartridge is basically a 400 Brown-Whelen with another name.

Those interested in the 400 Whelen will find lots of info on the web, see this:

If I bumped my head in the shower and staggered out thinking I needed a 400 caliber or thereabouts I would just build a 416 Taylor and call it good. Did it as a matter fact. Have the reamer if anyone is interested in building one.
IIRC Remington Jim built one with my reamer.

Yes Sir ! and i was just out shooting it the other day ! Weatherby Vanguard action - Bob Jury #5 contour SS
22.5 " barrel - B&C Stock - Timney Trigger - B&L 1.5-6 Scope = Total 9 Lbs ! Horn 400 gr DGX over IMR4320 powder = 2425 FPS !
I'm gonna get a BRAKE installed on it for Bench test shooting as its a BIT Lively ! RJ

Easy to form brass- I just run 458 Win mag thru a full lenght size die and they fit perfect ! I did buy some Jamieson 416 Taylor head stamped brass for hunting loads !
