Straight Wall Cases
Straight Wall Cases
When being shot in a TC, do you crimp straight wall cases or do you try to seat the bullet against the rifling like a rifle cartridge? I'm going to experiment with a .41 mag for PHSC with cast bullets and need to know how to load them. I know I may be off the beaten path, but it's what I have and want to see if it would work. I'm not looking for loads, just how to load the ammo. Any help would be appreciated.

Re: Straight Wall Cases
Depends on the powder. Try both and see which creates the most accurate load. & I think the .41 is a great cartridge. I have shot it for years!

Re: Straight Wall Cases
Don't think you will be able to seat bullet out far enough to touch in a T/C,they have very long throat.Not much need for a crimp with cast bullets in a single shot, start with a reduced load,pressure builds quick in a closed action

Re: Straight Wall Cases
+1 what Steve said. My experience with straight wall cartridges in a TC have shown a crimp usually works best. But as Steve said a lot of that has to do with the powder you select. I found that 296 and 4227 like to have a crimp to get the pressure up as the bullet releases. My experiments didn't really show a big preference either way so I just crimped my rounds in case I wanted to use them in a revolver. Just another thing to experiment with. 41 Mag is a fantastic cartridge especially with cast bullets. Have fun experimenting.

Re: Straight Wall Cases
This project is still in the planning stages. I just wanted to know if the crimp made any difference. I guess I'll find out when I get some ammo loaded and get to the range. Thanks for your help.

Re: Straight Wall Cases
While all my straight wall case rounds are minute of ram accurate, they are one ragged hole accurate at 50 meters. I have always loaded them like any other pistol round with a crimp. Your milage may vary.

Re: Straight Wall Cases
I don't shoot cast, but my 338 whisper#2 is straight wall an it shoots better with a crimp than without.

Re: Straight Wall Cases
Does seem to be a situational thing. Some of my cast bullet loads prefer being crimped, but some actually get run with the case flare left intact! "Anti-crimped" as it were. And that's in revolvers. But not stout loads.
Re: Straight Wall Cases
If you are shooting any kind of ball powder, it usually requires a pretty
heavy crimp for good ignition.
