Black powder loads for .414 SuperMag??? (.401 WSL?)

[ohland]

Would a 1.6" .414 SuperMag case SuperMag case provide enough volume for FFg and a 215gr SWC to reach somewhere in the 900-1300 fps range from a 23" barrel?

I know the .401 Winchester Self Loading (41 caliber straight case that is 1.5" long) was a smokeless round from the get-go. 200 grain J bullet and a 250 grain loads were available. The .401 is close to being a rimless version of the .414 SuperMag (.401 is 1.5" long, .414 is 1.610" long). Perhaps someone has tinkered with this before...

NOTE: To the rabid black powder shooters that are intimately familiar with the case volume to bullet weight to bullet diameter permutations, I haven't dropped hammer on a percussion cap or a BP cartridge in probably ten (or more) years. Do not try to assign any deep meaning or hidden machinations to my question. Can I burn black powder in the 414 SM and have a decent fun gun, or must I use smokeless?

One way to find out all those questions.
Try it and report back here.

I'd bet you can get what your looking for.

As I was doing the dishes this morning, I considered the .45 LONG Colt (tweak!) that used Black Powder in it's 1.285" case. Makes me wonder about the .41 Rem Mag which has a 1.285 case as well.

For those with uninhibited imagination, the .303 Savage shares the head diameter and rim diameter. Think of the .375 Win and it's 2.02 inch length, compared to the .375 SuperMag at 1.610 inch....

.405 Win 2.583 case
.414 SM 1.610
.38-55 2.085
.45 Colt 1.285
.41 Mag 1.285
.375 Win 2.020 case
.303 Savage 2.015

Oops, time to obey the Brittany...

Good morning
I recommend 3F over 2F. Expands the brass faster for near no blowback. Plus you will pick up 10% velocity.
In the caliber 414 SM the 265 grain is as heavy as I tried. I have little doubt it would penetrate the chest of a corn cruncher at 50 yards and less. I never crony'd the load but it was supersonic out of the Marlin 336 I have chambered 414 SM. The DW with 8 inch barrel was just about 1050 fps if my memory is working.

All those straightwall pistol cartridges work great with BP. Your .414 will be just fine.
