Most likely they are but for my light loads they seemed to work well yesterday with 7.6 to 7.8 of Unique with a light crimp like used on .45 ACP
My length was 1.605-1.610. Trying for loads to keep the speeds in the 750-825 range.
Just trying to find a powder combo like the Cowboy Action loads of 750-800 FPS you buy of the shelf with 225-250 gr. lead bullets.
I didn't get any leading in the barrel from those old Speer 230 gr. bullets yesterday which was good.
Now I might just use some Alliant Black MZ a black powder substitute that cleans up like smokeless powder. I have 6 lbs. of that and it
would go well with the Remington 1858 and give 850 plus FPS without the pressure.
