Hey all, new here. As my first post, i need help with a wildcat i have been working on with a friend. The basic jist of it is, a 14.5x114 case cut off to 3" and necked down to .458". The design was suppossed to be able to send a 600gr borerider at 3500fps, but when quickload was run on it, it came up 500 fps short! Problem seems to be, .50 powders aren't near slow enough for this thing.

So, i have two questions, one, does anyone know where i can get powder made for such cartridges as the 14.5x114 or a 20mm.

Two, we will need brass, and as pretty much all of 14.5x114 is steel case, we need something custom. I asked on thehighroad.org about making some cases on a lathe, but they told me that it doesn't give the strength of extruded or drawn brass. So, how can i make some, or get some taht is not to expensive? My friend and i talked to a custom brass maker (bertram brass) but he wanted $20+ per case!!!


Thanks!

What about starting with the 20MMx110 suzy case?

that would work quite nicly too, but i still need a slower than .50 powder and brasss.......

No one?

the best I can do, is www.patsreloading.com. They have the 20mm cannon powder there. That or www.hightechammo.com. That is my good deed for the day.

Just out of curiosity why are you doing this and what will you use it for? What fire arm will you use? Is 5020 too fast burning? roger

Idaho Sharpshooter--thanks for the link, but what is the 20mm powder called? I didn't see anything that blatently said "20mm cannon powder" but i might have just missed it....


bartsche--This is something that will allow accurate shooting past 3.5k yards (read, past .50bmg ranges) and a REALLY FUN project. I will have to get a custom action (IIRC, lawton actions is the company that said they could) and probably make a custom stock. I know a LOT of people who do that stuff, just have to make the calls. I have never heard of 5020....is it for larger than .50 shells? if so, then it will work better

if any of you have a program that can calculate this case with slower than .50 powders, could you run my numbers? I can send them to you....

Thanks!

BTW, really expensive project. Bullets will be about $4 apiece (bullet only!) brass, somewhere out there, and a custom gain twist barrel. All so expensive......

Suzy cases and 14.5 brass cases are very scarce
and expensive.I know as I'd like to get some
for projects. Like Suzy cases for making 8GA FH
from and the 14.5 brass for making my 900HE,
but both cases are being bought up by collectors
and guys using them in guns they have for 15 to 40
bucks each. Build what you want from 20mm Vulcan
brass which is much more plentiful.Like the one
in the picture made 40 years ago by Bob Snapp a
neighboring smith and friend here in MI.
The slowest 20mm powder that most big name
surplus guys have is WC872. And you can get slower
new powder from VV. By the way make case full length
like picture and it is easier to use slow powders
and get much more velocity than 3500 with 600 gr...like
4500-5000. Ed

Ed--Thanks for your input,i really need to find a way to make my own brass, otherwise it seems as if i will have to be a bum with a really cool gun Thanks for the name of the powder,, do you know if quickload has it in its library?

As for more velocity......I might make a version like that, but i am wanting to keep some resembelance of barrel life and lack of recoil

I don't think Quickload has it.
As 50cal pointed bullets go, 600gr are light.
If all you want is for a 600gr streamlined
bullet at 3500 and you have a BMG sized
action, make a BMG improved. Should get
3300 to 3400 for sure..... Should be
doable as my 585HE gets a 650 gr over 2900.Ed

Okay, do you know of any program that does? If not, how do i calculate a good starter load for it?


I am going to mess with a .50 improved, but it might be a bit close to the .460 steyr. Thanks again for the info!

The powder, I would agree as aforementioned www.patsreloading.com

Okay, thanks!

Wow, was that ever fired? The case in the picture looks unfired, but that looks like it was a pretty interesting project. Can you share any more details? I've read that the fat mac burned barrels, so how bad was that?
