I saw a post in another forum by someone with a tight barrel asking about using .452 bullets in the orange sabot for .458 bullets. He said:

"I am fed up with having to put so much pressure to sit my saboted bullet in my muzzleloader that I took some
mmp orange .458 sabot an put some .452 bullet in them and tried to seat them in my barrel..... Well what a suprise
it had about 10 pound resistance but it was a pleasur no climbing on the ram rod to seat it...."

Have any of you guys tried this combination?
