Remember the original 1873-1886 Springfields were set to zero at 250 yds. If you want to zero closer you need to raise the front sight.

How do people do that? My front sight is a block with the blade integral to the base.
 
Google says the blade is pinned into the base and can be replaced with a taller one made out of flat stock. Look closely.

Somebody used to make a clamp-on globe front sight but I cannot today find one.
 
Mine was pinned in also. I just knocked it out, found a piece of AL of the right thickness,did a rough saw, marked and drilled it, and then filed it down at the range. The only problem I have is that the new sight is so high I can't mount the issued bayonete.
 
My original 1873 Trapdoor, mfg. in 1878, shoots Penn Bullets 500gr RNPB on top of 70gr compressed 2F about 3" high at 100yards. At least it groups about 4 MOA, given my inexperience with rifles I consider that pretty good. Too bad is also shoot 6" to the right!

I haven't tried to group the 405gr FPPB yet, I expect they would impact a little higher as the velocity would increase.

These are fun guns to shoot with Black Powder and will get attention at the range.

How in the world did you get a full 70gr of FFg Black Powder into a 45-70 case when topped with a modern 405gr internally lubed bullet? (especially when using FFg) I thought the older black powder rifle cartridges and the 45 Colt never did fit the original powder charge in the case once we moved away from using a healed bullet.
 
I shoot 72 grs of goex 2f with the original government 1.1 inch bullet, and 75 grs with patched bullets.
Just use a slow pour into the case and follow up with a compression die so you don't smoosh the nose of the bullet when seating.
Thousands of rounds go down range every weekend at various shooting event folks shooting 70+ grs of 2f black and 500+ gr bullets out of 45-70's.
