Sight Adjustments At Matches

Post by DnL627 » Thu Jan 03, 2019 11:45 am

Question for you all: Do you adjust your sights for each animal's range or do you have a set zero for one specific animal's range and use holdovers/unders for the rest?

Background: I dipped my toe into SBCL matches using a Henry that came with Skinner peep sights. The sights did not have precise adjustments, so I set my zero for Turkeys and used holdovers and some Kentucky windage on everything else. Practice, along with trial and error, gave me a rough idea of where I needed to aim but it was not a very precise system. To this point I had been using it for all of my matches so far. I replaced my Skinner sights with a Williams FP-GR-TK w/ target knobs and a Lyman Front Sight 17AMI. I will start shooting this setup at my next match.

The Williams sight has a ton of fine adjustment capability that I am not used to. After I found my zero for each range I realized there could be 15-25 clicks between adjustments for settings and the white hash marks on the sight noting elevation don't seem very precise. If I start at rams and move to chickens that is a whole lot of clicks to count and potentially lose track of in the middle of a busy match.

So, how do you all approach your zeros and sight adjustments for matches? Any advice, tips, or tricks will be most appreciated!

Using a Williams FP/tk
I tape a piece of paper next to the hash marks.
I sight in using a rest then shoot offhand to fine tune. Then I mark that position.
I also figure out the the particulars for that rifle.
My Henry 20 inch octagon and Marlin Golden Mountie are very close. .
Henry .192 MOA per click
Marlin .195 MOA per click.

From what I've seen, Most people I think count clicks.

I use a small cut off wheel and cut a groove in the top of the knob for a reference point and use 1/4 turn increments for my settings. I also remove the windage knob and replace it with the screw from the hunting sight as I rarely make windage adjustments and don't like it hanging way out there. You got the knurled screw for the vertical slide lock right?

It is easy enough to use one setting for chicken and pigs. Chickens at the feet and pigs center of mass or what ever.

Find your sight settings for each animal, with chicken as your "zero" settings. Write down the setting. As you noticed, there's no reference mark on the elevation knob from the factory. I use a tiny spot of white epoxy paint from a bottom designed for appliance touch-up, and above it was mentioned that you can mark the elevation knob with a cutoff wheel also. I also mark the windage knob for reference, but rarely move it. I have also marked the slide in the past to refer to along with the elevation knob mark but don't really do that anymore. I just have the setting written down in my notebook for each ammo type that I am using, since they differ in point of impact.

I have heard second hand that there have been good scores shot by shooters who used one sight setting and holdover/under, but I have never seen it done. I don't know anyone who shoots consistently high scores who does it. It's much easier to have point of aim (whatever that means with your chosen sight picture) equal point of impact when shooting. The game is hard enough without making it harder and introducing estimations into the necessary sight picture to break the shot and hit the target.

As was also mentioned above, make sure you get the knob to replace the elevation lock screw for that Williams FP sight. You do need to lock it down to prevent it from wobbling, and having to do that with a flat head screwdriver every time you adjust is a pain.

A rear sight with a vernier scale solves all the problem with counting clicks, white paint, etc. Works every time. Look at what the BPCR / BPTR guys are using and you will see the utility of a vernier scale. They work just as well on a lever rifle.

All good suggestions, may I add a bit more?
Think of the Williams sight adjustment in terms of full revolutions up or down. For example:

Pigs at the Zero Mark
Turkeys at 2 revolution up
Rams at 2.5 more revolutions up (total of 4.5)
Chickens at 1/2 revolution down from Zero
(depending on you ammo)
It is easier to mark your complete revolutions in a target book, or piece of painters tape stuck to the stock, than to count clicks.

Just make sure you turn the knob the correct way, after you loosen the Gib Screw!

I use Marbles tang sights on all three of my lever guns, SB, PC & CLA. 8 clicks per turn. I count turns then clicks for my settings. Super easy to adjust and if I forget where the setting is just spin back to zero. The only caveat with the Marbles is that you must tighten the lock nut after making the adjustment for the sights to be consistent.

Here's my setup. With the top (yellow) tape lined up and the adjuster knob mark at 12 o'clock, I'm on chicks. A 1/2 turn out puts me on pigs. An additional 1.5 turns out lines up the middle tape for Turkeys. One more turn out, for 3 turns out total, lines up the bottom tape for rams. This works for my particular 22LR rifle/ammo combo.

This tape is pinstripe tape from the local hobby/modeling shop.
