WyoJoeCase Capacities????????????
I was looking through my reloading manuals last night with the idea for a wildcat running through my head. What I was thinking of is the .300 WSM necked up to 9.3. Does anyone have a balistics program that figures case capacities? I was thinking this might give 9.3X64 Bren. balistics in an easier to obtain case. I know it can be done with one of the belted cases but I want to stay with a beltless one.
Thank You

Bob338Either Quickload or AccuLoad do that. I have my copy of AccuLoad uninstalled presently or I could give that to you. Probably someone else with either one will step in and help.

TailgunnerRCBS software
300WSM with a .030 wall taper holds 74.8gr water to the base of the (.297 long) neck.
Keeping the body the same length to shoulder (1.6640), and maintaining the 35deg shoulder, the same software shows a capacity of 73.8gr water to the base of the (.338 long) neck.
Keeping the .297 long neck, and 35deg shoulder angle, but blowing the body/shoulder joint forward (to 1.7056) yeilds 75.8gr water to the base of the neck.
Hope that helps you.

Gonzo FreakPowerIs there anyplace online that lists case capacities? I've been looking for a way to compare capacity between a variety of cartridges, like 260Rem vs 257Rob.
If someone could post the URL of a site like this, I'd really appreciate it. I hope it'll be another tool in my search for the next rifle.

That program (RCBS Load) has (among other things) a "cartridge designer" function, with has a large number of "referance cartridges" including the 300WSM and 9.3x64 Brenneke. It only took a couple minutes of playing to "re-do" the 300WSM into the 9.3/300WSM for you, and it keeps track of the capacity changes as you go.
It dosn't however do the powder type/powder amount/pressure/velocity calculations of the Accuload / Quickload programs.
Sometimes when I'm bored I'll "sketch" up somthing weird just for grins (30Carb necked down to 17cal anyone?)

SabotThe above case with 73.8 grs of usable capacity and a .366 cal bullet can safely generate 4393 FPE. If you chose to correct for the efficiency of the short power column this becomes 4653 FPE.
This is definitely 9.3X64 territory in a short action rifle and a very good idea. For those wanting the increased flexibility of 35 Cal, these numbers become 4278 and and 4532 FPE.
