500 grain .45-70

I have a whole box of 500 grain .458 bullets that I hate to just leave sit. Has anyone shot these in a contender? Do you have a load that you would recommend? I don't want to run the risk of hurting the gun. I've got a 16in unported barrel. Don't worry about recoil for me, just the gun.

Reloading The .45/70
(WC= WadCutter, SWC= Semi-WadCutter, HP= Hollow Point, RN= Round Nose, FMC= Full Metal Case, FMJ= Full Metal Jacket, JHP= Jacketed Hollow Point and if GC indicated, means Gas Check at bottom of lead bullet)
Loads for .45/70:
(Note: These are near MAXIMUM loads, you should use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Bullet sizes vary from .458" for jacketed to .459" for some lead in diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.
These loads are for MODERN guns. Make sure your gun can handle it. Powder Mfgs. Velocities in a test barrel differ from a 4 4/5" revolver by about 175 fps and from 7 1/2" by 50 fps. Some of these velocities were shot in a 10" or a 14" barrel, similar to a Thompson Contender. Recoil is severe with these near MAX loads. You should consider 10% less for starting loads. However, with something like 2400, which is really a pistol powder, too little can be as dangerous as too much. It's a big case. With the powder down at the end near the bullet, it can cause problems or even an explosion with minimum loads (or less). Be advised.
Do not use any of this data with guns designed for black powder loads or any original TRAPDOOR rifles, EXCEPT WHERE NOTED that it is a "TRAPDOOR" Load. If condition of old gun is doubtful, even these loads could be risky. Consider using original Black Powder loads and lead bullet for old guns.

Discussion: This is a very old cartridge. It was introduced in 1870's in the Springfield "Trapdoor" rifle. Do not use any of this data with guns designed for black powder loads or any original TRAPDOOR rifles, EXCEPT WHERE NOTED that it is a "TRAPDOOR" Load. It's best to use new brass. Some old cartridges also used corrosive primers. I recommend lead bullets and loads in the neighborhoon of 1100 to 1200 fps as maximum for TRAPDOOR rifles, unless you are sure of the gun.

Quite honestly, I'm relieved that you have pulled back some from the 500 grainers. I spent a couple of days shooting those loaded in a 45-70 through a Ruger #3 without a pad and I suffered for a while after that experience. I know that it's an overused phrase but that combination in a Contender is a real handful.
Best.
