Shooting low at 100 with buckorn and post
Posted: Mon Mar 06, 2023 6:23 am
Bretheren,
I went out to the farm yesterday and had a GRAND time getting more acquainted with my 1874 Lewis and Clark commemorative. I'd like to get some experienced opinions on this matter.
Right now, I'm trying to become proficient with my barrel buckhorn and front globe post sight. The front sight is literally a thin post that looks like an "i", surrounded by the steel globe. No inserts.
I'm hitting consistently 3 inches low at 100 yards. My 45-70 load is:
- annealed Starline
- 70 gr of Goex FFF
- 405 gr Hunter Supply flat point, flat base
- Lube is 50% beeswax, %50 lamb talo
My chrono is telling me my velocities are around 1300.
There is evidence on the tang that the prior owner did us a vernier type sight. What I'm wondering is, since the front sight is not the stock blade, could it not be regulated to the installed buckhorn rear? If the front post is too high for the buckhorn, then it makes sense that it would shoot low.
Or, am I pushing the bullet too fast, thereby it being in the barrel for a shorter time and hitting low?
I'm ready to get technical on this rifle.
PS, I plan on purchasing a soul sight when I get the funds together. Then I'll graduate to a heavier 500+ gr bullet.
