Re: 500 Jeffery based wildcats

Rocky Mountain,

Have yet to receive my custom case forming dies from Whidden and the reamers from PT&G...

will be using a 30" 10 Twist Benchmark barrel for the 375 Mjolnir
so may not have the full potential of this round, have a long wait for a 34" er

also a 30" tube for the 338 Wolverine until I get the longer one...

the Pigman shoots 250 gr. Hornady bullets at 3400 fps in his 338 Twisted Pig,
my 338 Wolverine has a bit more case capacity and the tougher 500 AHR brass,

without being too optimistic.... my velocity goal for the 338 is around 3200 fps with 300 gr bullets but that is just an estimate based on case capacity and velocity comparison to other cartridges,

Re: 500 Jeffery based wildcats

Any idea how this compares to .338-378 Wby case capacity/performance and .338-416 Rigby case capacity/performance?

Seems like itll fall right between the .338-378 and .338 Allen Mag?

Also, not trying to go off topic. But has anyone heard any recent updates on Mr Daves .375 Viersco Magnum? Has there been anyone else to wildcat off the .577 T-Rex case? I know State Arms or something like that used to have the .375 Mach V, a .375-50BMG. But has there been any recent .375-416 Barrett wildcats or .375-50BMG AI wildcat developments?

Mr Swamplord, what velocity are you expecting with the 350-400gr Cutting Edge VLD solids? If youre planning on testing with those of course... Either way both of these cartridges with the right boolits should make great 2400-2800yd cartridges easily.

Re: 500 Jeffery based wildcats

Laser......


I posted this info earlier and all the case capacities are from the ammo guide website.... the case capacity for my 338 Wolverine is from the Quick Design software...

I don't know how accurate either source is and will be verifying that info as soon as I have a handful of fired cases in my hand and will post the info on this thread......

338 Wolverine case water capacity 145.2 gr


approx. 18 gr. more than the .338 Excalibur
23 gr. more than the .338-378 WBY
27 gr. more than the 8.59 Lazzeroni Titan
33 gr. more than the .338 Lapua Mag
37 gr. more than the .338 Edge
40 gr. more than the .338 Norma Mag and .338 RUM
62 gr. more then the .338 Winchester Mag
(these are ammoguide water capacity estimates)

all these estimates may vary + or - a grain or two, just a ball park comparison to give you an idea of case capacity.......

the 338 Wolverine is based on the max case length of the 500 Jeffery.....

another option I have been playing around with is using the max case length of the 500 AHR (about 1/4" longer) just use the 338 Wolverine reamer and go deeper, Quick Design shows about 10-12 gr more capacity but will require deep seating of bullets because of COAL limitations .... on a larger action It won't be a problem..... I will probably end up doing that as soon as the bbl needs to be set back, I'll just set the bbl back a few threads and run the reamer in deeper , touch up the muzzle and give her hell !

338 Wolverine + Teeth ? lol....

I do have plans for using the heavier CE bullets, just haven't got my hands on any yet and couldn't tell you the velocity without lying .......
