Hornady .452, 300gr...for 45/70 and w sabot for a .50?

[skeet]

Which Hornady bullet? If you meant the 452 bullet in the 45-70. In a word ..No. If you mean the #4500 300 gr HP by Hornady. it is made for the 45-70. I have a box or so right over the computer desk. They however will not work in a muzzleloader without fitting them to the correct sabot. I use the 250 gr 452 bullet in my Savage muzzleloader with the correct sabots. It is good to 250 yds in the right hands. Not necessarily mine. Those powerbelts are what size? I also use the 250 gr 452 bullet in the 45 Colt. They would rattle down a 45-70 bore.which measures approx. .458
