Quick question here-

On my packs of MMP sabots (these are the tan, .45/40 sabots) it says to never load more than 80 grains blackpowder or RS equivalent. This sounds awful weak for a max load to me. Are they concerned about people blowing up old barrels with magnum loads, or are the sabots only designed to function properly at these velocities?

I'd like to work up a 90 - 100 grain 777 load, but now I'm worried that the sabots won't work properly at that speed and I'll get bad or erratic accuracy.

Thanks
