I believe your starting loads may provide clues to what it takes to cycle the 07 action. I like 296 in some RBH-only 45 Colt loads. Should prove interesting!

Having done some research, the balance of opinion favors very fast rifle or magnum pistol powders,  with some specific starting recommendations of 16 grains of 4227, 2400, or 296/110. 

Because I have good quantities of Olin 296 on hand and have had good experiences with it, all the way from 22 Hornet to 357, 41, and 44 magnum,  I propose to make up a ladder from 16 to 18 grains of 296, using Winchester WST large primers, Graf 180 grain brass plated RN bullets, in what are likely modified Remington brand 357 Max brass, now once fired. 

Ten of the Graf bullets have been seated to factory OAL and roll crimped in the cannnelure of once fired, dead/inert primered, FL resized, vintage Western brass. Loaded into a 5-round magazine, these were fed and ejected repeatedly using the operating rod sleeve, to test whether these bullets and the 07 feed ramp can get along. They can. 

When Winchester-Western discontinued their SuperX commercial ammunition  [W351SL2], the 180 grain softpoint bullet was advertised to have a muzzle velocity of 1870 foot seconds from the 20" barrel, producing 1400 foot pounds of muzzle energy. Not a pipsqueak cartridge. I'll chronograph my loads but all I'm looking for is from 1600 to 1700 foot seconds.

I'd welcome comment, particularly from those with reloading experience in the caliber.

Dang it!  My patent attorney dropped the ball and those Texans beat me to it.
I put the XL on my Christmas list but will still shoot prone from my REI tent.
Thanks for the link!

Now I’m confused.  Why is she shooting instead of picking up the brass?

Yellow light!!

I have an uneasy feeling the requisite dinner will have to be some place so dim I can't read the menu,  the Maitre d' will have a posture like a cobra and his hand out for a C-note to avoid being seated downwind of the grease trap.

I probably could have bought a Korean brass finding robot for half the probable meal tab. Big D really is the Land of Wretched Excess.  

But I've grown accustomed to her face.

If your wife can't make it you can always pitch your tent and shoot from inside.  Not only will it catch all your brass but you will also be in the shade.  Make sure to keep the muzzle outside though or the window flaps fly up like Dumbo's ears every time you pull the trigger, just sayin'.....

Best Regards,

I loaded some Hornady Spire Point 180's when I thought the big piggies needed a bit more killing than their 165 delivered. Cool thing was the 165 and 180 had almost same point of impact at 100 yards so no need to re-zero or allow for the different bullets.

The 120 - 130 grain bullets can duplicate 270 ballistics out to about 250 yards. Handy and light recoiling.
  

I bet they are.  Most of my .308 caliber supply are the Sierra 150-gr bullets.  I load them for two of my 30-06 rifles, and for my Springfield 30-40 Krag rifle.  The heavier bullets are for my 30-60 Benchrest rifle.  I load the 180-gr and 220-gr for both of my 30-40 Krag high-wall Single Shot rifles.  Somewhere deep in my ammo box I still have a box of (20) that my grandfather loaded using 90-grain M1 Carbine bullets back in the 1960s.  I remember shooting some of them as a kid... no recoil, but a LOT of muzzle flash!

Got 4800 at an Auction LRP at .06 each. Used to get at Sportsmans or Scheels in Colorado, but won't go thru there again till July--God Willing..
  

We lost our Sportsman's Warehouse here in DFW and I was sorry to see them go. Scheels showed up with a freaking huge megastore but prices were for suckers.
