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 [ 09-28-2003, 02:22: Message edited by: WyoJoe ] | ||

Either 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. | |||

RCBS 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. | |||

Is 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. | |||

For case capacity references you might try this url: www.geocities.com/CapitolHill/Lobby/1221/case_cap.htm Russ | |||

73.0gr water, to the base of the neck 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?) [ 09-28-2003, 15:51: Message edited by: Tailgunner ] | |||

quote:All capacities are nominal "grains of water" to the base of the neck. Case wall taper is the average, not the extreams (IE: using .030 taper with .020 and .040 wall taper extreams). Working pressures are not given, and come into play with your decision. Enough of the disclaimer stuff. 25 Rem 34.6gr 250 Sav 42.5gr 257 Rob 51.6gr 257 Rob Imp 55.3gr 25-06 62.0gr 25 Gibbs 66.9gr 260 Rem 50.2gr 6.5-257 Rob 49.7gr 6.5-08 50.5gr 6.5x55 Swead 48.6gr 7-08 Rem 49.8gr 7x57 Mau 49.2gr 7x57 Mau Imp 52.6gr | |||

The 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. | |||

There is also a 14 cal wildcat on the 30 Carbine (.14-30 Carb); this was developed by Eichelberger. the_captn | |||
