Sam's Gunsmithing.300 Arnold
Is anyone reloading for a .300 Arnold?
What powder and bullet weights are giving you the best results?
Thank you,
Sam

MarkReloading for it, heck I hadn't even heard of it!
Anyway, that said I did a quick google and see that it is an 8mm rem magnum necked down to 308.
Here is a nice lefty 700 for sale:

Best Hunting Load: 82.5 grains VitaVhouri N165 powder, 180 grain Nosler Partition bullet, Federal 215 M Primer, 3.278” overall cartridge length. Shoots very accurate ½" to 3/4" groups with this load at 100 yards. Velocity 3200-3250 fps on 45-50 degree day at 500 ft elevation, based on my chronograph.

KRyder8mm Rem Magnum necked to .308 would make it comparable to a 300 Weatherby (without the radiused shoulders).

homebrewer www.ammoguide.com shows 62 loads for the 8mm RemMag. Choosing one in the bullet weight of your choice for .30-caliber should give you a place to start for the Arnold. Just reduce the load for the 8mm by 10% and start the development process...

Absolutely.
If I was working up loads for a .300 Arnold, I'd be looking hard at .300 Weatherby data as a base. In fact, the two might be identical in data but would be conservative and work up from minimums for the Weatherby.

Ol` JoeDan Arnold has wrote a few pieces for Precision Shooting Magazine and they should be able to tell you how to get ahold of him or pass a message on.
He was the owner/developer of Arnold Arms and the Arnold line of cartridges and should be able to give you some data for your 300.
