If this is your first time here, start at the beginning to see all of my experiences.
Converse Meadow Pond, Rindge, NH temp: 48.7 F (9.3 C) (9.3) humidity: 85% wind: Calm pressure: 29.85" (1010.7 mb) station: KNHRINDG3 hardware: Davis Vantage Pro 2 updated: February 24, 7:18 PM EST local forecast
To keep things simple. The marks on the side of the staff are a vernier scale that can be used to make .010″ graduations. You can look up the vernier scale on Wikipedia and see how it works if you have ever used on before.
A .010″ graduation basically equals a 1 minute of angle move, or one inch per hundred yards to the target.
There are 5 marks on top of the elevation knob and they represent 1/2 minute of angle each for fine adjustments that can be made without the aid of a magnifier.
For windage adjustment, the right hand knob is graduated. Each little mark is equal to 1/4 minute of angle just as most good scopes are. Every 4th little marks is numbered just so you can keep track of where you are in the rotation of the knob.
You can see the lines on the back of the staff at the bottom that were kind of dim when you got the sight. Those lines in conjunction with the center line on the body of the sight will tell you how many complete turns of the windage knob you are from center. Each complete turn of the windage knob is 3 minutes of angle, so if you are 4 lines from center then you would be 12 moa from center.
In use you adjust the sight till the elevation is correct for a specific distance and note where the lines are on the vernier scale and keep track of that sight setting in a note pad. Do the same for the windage, but the windage will vary according to how the wind is blowing.
The picture below is my sight set for 300 yards. It is set to .45 My current load is 1.6 moa/10 yds.
Had fun this past Saturday shooting at the Major Waldron Sportsman’s Association hosted by my cowboy pard Dead Head.
Course of fire was 10 rounds on 200yd with sticks, 10 rounds on 200 yards off hand, and then 20 rounds on 300 yards.
My scores were 6, 1, 8, 6, for a total of 21. Pretty crappy but it was my first real shoot and my first time shooting beyond 200 yds.
My almost 12lb rifle is just too heavy for me to shoot offhand…I need to do some strength training and figure out a stance which provides more support.
I was pretty happy with my score of 8 on the first stage at 300 yards. I was shooting my loads of 70 gr KIK 2f, a veggie wad, Lyman Postell 535 gr I cast and lubed with 50/50 beeswax/mutton tallow. I had a couple of misses which I know I was right on the target through the trigger pull and they were nowhere to be seen. I was shooting a mix of new, not annealed brass with older, fire formed and annealed brass so I don’t know if that had anything to do with it. In any case I’m going to again anneal all of my brass for the next time.
I was lucky at the 300 yd target because I calculated that I needed to raise my sight 16 moa (1.6 moa or lines on the vernier per 10 yards) and hit it reasonably well on the first sighter.
I seated my bullets about a 32nd” deeper this time so I didn’t have to wrench each round in and used the blow tube between each shot. That worked because I only needed to wrench in two rounds out of the 50 I shot.
Well, that’s it. I have some loading to do before the next shoot on the 12th of December….hopefully the weather holds.
I’ve been busy with work and I’m on a plane as I type this on my phone trying to get home in time to head to Vermont to participate in the Green Mountain Mayhem. I have been shooting my rifle at these marches but haven’t had the chance to get to the range in between to practice.
I’m still not an expert with the vernier but have been lucky enough to guess correctly for a couple of 200m matches. The last of which was the New England Regional a few weeks ago where I forgot my blow tube and suffered 3 misses on the final 3 shots. Other than that my loads seemed to work fine.
They’re going to close the door on the plane so I have to end this now, but will catch you up in another post.

So I set up my 80yard target in my back yard and proceeded to shoot a bit using the rounds I had loaded up with the new veggie wads. My group seemed to be pretty tight for my sitting position … Continue reading
I wanted to be able to see down my rifle barrels to check for leading and other things but I couldn’t see spending hundreds of dollars on a good borescope. What I found on Ebay is a cheap 20″ long … Continue reading
So far I had been using some card wads I bought from Track of the Wolf but I’ve been reading that veggie wads come off the bullet quicker allowing for the bullet to stabilize more quickly. Some folks don’t report … Continue reading
