Shavers sight instructions

[jgh4445]

My Lyman Model of 1878 ( actually a close copy of the 1877 Sharps by Pedersoli) is wearing a Lee Shavers long range sight. Lyman 17 front globe. I have the .22LR insert for the barrel and was shooting decent groups with it at 100 yds this past weekend. In order to hit center of the 6 inch bullseye, I had to use the tallest post I had with the rear sight adjusted all the way to the bottom and actually bottomed out.

Now our range has opened the 300 yd range back and I want to try my 45-70 loads at 100, 150 and 200 yds. I'm pretty sure I can get back on at 100 easily enough, but having lost the instructions for this sight, I'm wondering what the formula is for dialing in the drop at 150 and 200.

I'm shooting a postell 535 gr over 64 gr 1.5 swiss with .200 compression and two .030 wads. Don once gave me a hint on how many hash marks on the staff it would take to get to 200, but I lost that too. Anyone with experience with this sight want to hazzard a guess ? OH, its gonna be even more fun cause the 150 and 200 yd shots will have to be made from X sticks. We have no bench set up. Doubly fun since I've never tried shooting from them before. Heck of a first post huh?

Each one of those hash marks on the staff will be about 5 minutes. So if you start with a 100 yd setting you'll need about 2 of those marks for each 100 yds beyond that.
Depending on your front sight height, velocity of your load etc. somewhere around 25 should be a fairly good place to start.

OK, The staff's moving slide has 5 marks. One is a longish one identified by a zero. I'm ignoring the other marks on the moving slide and just using the "0" line as a reference. When that line is perfectly lined up with the fourth "hash mark" on the stationary staff, the rifle clover leafs rounds in the center of a six inch circle at 100 yds. You're saying that about two more hash marks up will be about right for 200? I'll start with that and see what happens. Thanks.

You might look at the MVA instructions on this link. About halve way down you will find the instructions.

I don't know anything about the Shaver sights I only use the MVA but check and see if the adjustment graduations look the same.
As far as the come ups on the sights you will have to work out with your rifle and loads and record them in your brain book for future references. The come ups for a 30" and 34" barrels will be different on the down range impact.

Thanks Kurt. I'm sure my way isn't correct, but I only need 150, 200, and 225. ( these are thee longest shots from my three shooting stands on the deer lease.) Thought I'd mark the sight with fingernail polish or something similar. Better find a hard copy book to jot the come ups down in. My brain book doesn't have many pages lol.

Hi,

The Shaver sight elevation graduations are the same as an MVA. I can't say with respect to windage as the windage marks on my deluxe Shaver are nearly unreadable.

All of my rifles will get on paper by adding 15 minutes from 100m to 200m. Once you are on paper it's easy to fine tune. I like to use red targets as it's easier to see the bullet holes.

Two things to keep in mind when you are getting ready to hunt;
1. Practice from the same elevation [stand] as you will hunt from.
Up hill/ down hill are not the same as level.
2. If your hunting is in the Fall or Winter, practice from your stand elevation during the approximate temperature that you will hunt in.

Keep on hav'n fun!

Mike, thanks for the advice. Those things are pretty much standard procedure for me. As a matter of fact, I have flagging tape at various yardages and will shoot a target at all of the distances about a month before gun season comes in. We also practice form our tree stands before bow season to.
