.375 Crudmoor? Nice! Now you've done it! A new wildcat for the large bore wildcatters on here. You need to start a thread here and have Bruce Moulds and Bob Whelen work up some loads for it. I'll bet with a 235 or 250gr bullet, It'll become a very attractive cartridge for the "man larger bun" crowd!
1 dirthawker,this is an interesting thread and i will attach some more information to it. (i own neither a 35 whelen OR 9.3x62 ...yet
this is a list of cartridges and their water capacities in grains taken from 2 sources:
30-06 69 gr
35 whelen 70/71 gr
338 winchester 85/86 gr
9.3x62 77gr
9.3x74r 82gr
375 h&h 95gr
so, clearly the 9.3 has an advantage in case capacity. also as bore diameter is increased, the same weight of projectile, at the pressure...the larger the bore, the faster the larger/more energy the larger bullet will go with the same power plant. there are efficiency gains, take for instance the
7mm mag: 3000 ft lb 175 gr
338 win : 4000 ft lb 250 gr
458 win: 5000 ft lb 500 gr
3006- 3000 ft lb 180gr
35 whelen 3500 ft lb 250gr
of course this is a generalization. it would appear that a 35 whelen with less case capacity AND bore diameter, pushed to the SAME pressures would have slightly less energy with the same weight bullet.
now @Bob Nelson 35Whelen this is not me dirt shirting your favorite caliber, this is just an observation based on previous information i have seen/read i will follow this up with an article from a site called impact Dynamics
I'd like to see a pic of the .375-.300WM if you ever find one. Like many things, I've thought about a .375-.338WM since I have a lot of .338 brass? Interesting .260 Improved wildcat?
Nice! Your going to have your own line of resurrected or maybe even NEW line of wildcats! Put them on line somewhere and see who takes the bait? Entertainment!@Bob Nelson 35Whelen
I went back and made you a .375-308Pictured here with a .375 Ruger

Well, I know the '06 has been necked up to .40 (.400 Whelen), not sure about the 9.3, but I think you might have a winner with the .375 Winchester? I don't know that it's been necked up above .35? Actually, the .375 Winchester is based on the straight walled .38-55 rimmed case, so you have a different cartridge based on the .308 case.
Your .265IWB (perfect!) appears to blow the Crudmoor out of the water ballistically? The .375-.300 appears to give the Ruger a run for it's powder charge? Especially if one has copious amounts of .300 brass laying around? Where's those reloading ballistic gurus Bruce and Bob at? They go to bed already?
the 9.3x62 is pretty close to a 9.3-06. i believe the 06 has been necked up to .411 or 416, can't remember what they called it. if you have a 338 win, you have a great cartridge already!! i had one and hunted it for 20 years. ended up trading in for a 375 ruger. shot lots of deer, caribou, moose and bears with the .338 win.
Yeah, I know we're constantly splitting hairs here with these cartridges as far as actual effect on game animals. But, it's fun and entertaining this time of year with no real hunting seasons available and not much else going on here in the U.S. Heck, you can't find much ammo to just shoot with! I was in a local gun store today, and they had a bunch of Remington .25-06 for $20/box and 7.5x54 (Chinese?) at $20/box. Everything else was $40-60/box. I haven't had time to reload much. So, here we are?
I think my .265 has potential, now that you mention it. I made these for fun, while sitting around talking with my son. It does obviously have more case capacity, and has the 25° shoulder. In a 1:8 barrel, it would be phenomenal.
My .375-300 has slightly more capacity.
I never found the neck to be an issue on a .300 Win Mag. I've told mine repeatedly, that it can't be accurate with only a .264" neck. Stubborn are keeps shooting 1/2" groups lol
.338 Ruger Compact Magnum?
Forrest,
