Default Issue with PPC revolver and BoMar

It's a 1978 Clark Custom Combat that I've had for over 10 years and am just now shooting it for the first time.
It sports a BoMar 6" rib and a 1" HB.

As it's the 1st time out shooting I brought the rear sight all the way down and set my target up at 10 yards. Took two shots and the bullets weren't even on paper. My daughter says, " they're in the dirt". I couldn't believe it. I raise the sight about half way up and now I'm still about 2.5" from POA = POI

Am I starting to close? Are these PPC guns suppose to be zeroed out further? The load I'm using is the same wadcutter ammo that destroys bullseyes at any distance.


Help, please!

PPC was shot at distances ranging from 7 - 50 yards. Most PPC guns were sighted so that a neck hold would drop the shots into the X-ring at center of mass - so what you experienced is normal.

Adios,

When I shot PPC, I used a center hold for 7 yards and neck hold for everything else. My revolver was built by Davis on a S&W stainless revolver.

What is a "neck hold"?

Neck hold is basically a 6 o'clock hold on the head of a B27 target, often used in silhouette or PPC competition. At longer distances many feel it's easier to adjust the sights, and place the top of the front sight at the base of the head, rather than aiming at the center of mass area.
The Aristocrat rib has a front adjusting sight that has three "pre-set" positions to accomodate sight changes without employing a screwdriver. Sight is changed by simply sliding the built in adjusting platform under the front sight. Rear sight "finger dial adjustable" model ribs are also available.

Correct, I had the Aristocrat Rib and easily made the adjustments for the various distances.

The neck hold was preferred by myself and others as the scoring rings were oval with the longest distance being along the "spine". The neck was an easily defined area and promoted a better sight picture. If you shot when wide of the neck, the bullets landed in the lower scoring rings. The high and low shots would still make a good score.

The front sight was easy to sight in, an Allen key would make the vertical adjustments. The rear sight controlled windage.

It has been a long time since I have even held my old competition rig. After I got the 686 for the Distinguished leg, I found my scores were quite comparable to the Davis revolver. Towards the end, I just used the 686 and was still pleased with my scores.

The PPC guns are not sighted like NRA Bullseye competition guns are.
Clark Custom would install the sights for the owners preferred competition.
Clark Custom Guns are still in business and I'm sure could adjust/alter the sights for your requirements.

I just acquired this week a slightly used model 10-5 old PPC gun from the 70's. It is sighted in at neck hold, shoots very low. It has a Bomar sight rib and to achieve a slight 6 o'clock hold the back sight adjustment screw has to nearly all the way out and it looks rather odd like that. I took the rib off and I'm thinking of adding a couple of washers underneath the back of the rib, around the rear mounting screw. I'd get a shorter front sight if I could find one.

IIRC, when I used a Bo-Mar rib, in order to shoot neck at 25 yards the elevation screw would be turned clockwise 2 1/2 complete revolutions from the center hold position. This would be close to as far as the screw would turn. So, to get close to center hold turn the elevation screw clockwise until it stops, then back off 2 1/2 complete revolutions. Neck hold at 50 yards would be one complete revolution clockwise from center hold. These are approximate, and based on memory that is 30 years old.

What you have is a west coast style rib. I learned this back in 1978 when I ordered a bolt on rib for my heavy barrel model 10. I couldn't sight it in there wasn't enough travel in the rear sight. I called Bo Mar and the neck hold was explained to me. I wasn't shooting PPC so the west coast style wasn't what I needed. IIRC they exchanged it for me, you may be able to cut down the front sight enough to gain adjustment.
