When I purchased a Hiwall a few months back it came with a nice Zitka sight but I took it off and used a scope to try to develop the most accurate breech seated load in the 32/40.  The rifle came with a newer Douglas barrel in 40/65.  The 32/40 and breech seating kind of got me highly interested so recently I bought a second original Hiwall in 40/65 for a hunting rifle thinking that if the barrel on it was toast I would install the Douglas.  Long story short the original barrel turned out to be a 40-60 rechambered to 40-65 and doesn't shoot for beans.  I put the Douglas on and removed the Lyman Tang sight and put on the Zitka for load development and might even hunt with it.  The Zitka sight has a 30" sight radius and if I do my arithmetic right each graduation on the main slide should move my impact 1" at 100 yards.  There is 0.5" between 0 and the 1 which would be 60 points if I have the nomenclature correct.  The Vernier is pretty basic to go between 0 and 5 points.  So if I am shooting a 400 grain bullet at blackpowder velocities and zero at 50 yards, approximately how many inches would I need to raise the sight to get close at 100 yards?  Then how many more inches would I need to move to get close at 200 yards?  I have no idea what the bc of a Snover bullet is to look on trajectory calculators for my answer.  Also, what would be an approximate bc for a flat point 400 grain bullet?  All loads will be fixed ammo for hunting.  What velocity will a fixed load generate with black with about 50 grains as the bullet takes up quite a bit of capacity.  I might drop down to a 350 grain flat point for hunting to get a tad more velocity.  Only 4 months to hunting season!    Tom

  I've never heard of a Zitka sight before, but it looks just like the ones Frank Zika used to make.

Holy Cow! That vernier is scaled for 1/4 minute adjustments. Each number is 1 minute of angle or approx 1" at 100 yards. BC of rifle bullets doesn't matter a great deal at short ranges. What ever bullet you shoot, when you get a 50 yard zero come up 6 or 7 minutes to get on paper at 100 yards. Then come up 15 more minutes to get on paper at 200 yards. You will need to fine tune it after getting on paper. Be sure to write down your results.

I’ve heard that some of the old timers used a magnifying glass to adjust their vernier type scopes.
