Dustem Dave Posted February 27, 2011 Report Share Posted February 27, 2011 Hi guys,quick question if you raise the comb on a sporting shotgun does it make it shoot higher or lower? Quote Link to comment Share on other sites More sharing options...

Dustem Dave Posted February 27, 2011 Author Report Share Posted February 27, 2011 higher. So if i lifted my comb an eighth of an inch how much higher would it shoot at 40 yards?? Quote Link to comment Share on other sites More sharing options...
Gordon R Posted February 27, 2011 Report Share Posted February 27, 2011 Quite a lot. Quote Link to comment Share on other sites More sharing options...
southrop Posted February 27, 2011 Report Share Posted February 27, 2011 Five inches if you aim your gun like a rifle. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted February 27, 2011 Report Share Posted February 27, 2011 The theory is one thing, but I would wager a small amount that it would be more. 1/8" on a stock is a lot. Quote Link to comment Share on other sites More sharing options...
southrop Posted February 27, 2011 Report Share Posted February 27, 2011 Could be Gordon R you might be right. I always thought that raising the comb had little effect anyway on poi unless you aimed like a rifle. Lowering the rib relative to the barrels is the only real way of raising poi. If you keep your eyes glued to the bird you can shoot effectively from the hip and that's equivalent to raising the comb a foot! Quote Link to comment Share on other sites More sharing options...
clayman Posted March 3, 2011 Report Share Posted March 3, 2011 Quite a lot. Not really - a comb too low is always a problem as the eye is behind the action and the shooter will either look down the side of the barrels or lift their head, resulting in the gun not shooting in the direction of the vision. The ideal is the pupil of the eye about 3mm high on the back of the rib when the gun is correctly mounted and the eye/rib relationship is viewed from the front ( safety - always prove the gun is empty before performing any gun fit work by some-one viewing from the front!!) How-ever, combs set high still provide the vision of the rib for aim and only have the effect of making the gun shoot high. Its actually surprising how little extra eye height adds to the point of centre pattern placement. At 20m and eye position 1/4 high ( 6mm ) only raises the pattern by 12cm - or 4". In a pattern of 30" this amount is not very critical. To get "very high" the comb would need to be, say 1" too high ( that's massively too high in gun fit terms) and even so this only results in a centre of pattern 50cm or 18" higher than a normal pattern placement. Its FAR better to have a comb a little too high than it is to be too low. If in doubt, set the comb up and then fine tune back down as shooting improves.

Gordon R Posted March 3, 2011 Report Share Posted March 3, 2011 Any set up where the comb is high is fine for rising targets - allegedly, but the complete opposite for dropping targets. Guns should shoot flat for sporting. Quote Link to comment Share on other sites More sharing options...
clayman Posted March 3, 2011 Report Share Posted March 3, 2011 No, myself and most coaches / gun fitters would disagree. A flat comb means the shooter tends to aim "through" the bead rather than "point" the gun to a clay in clear sight above the bead. Bead aiming has a tendency to make shooters stop the gun as they shoot, as they focus back to the bead to check lead at the moment of pulling the trigger. This is a very common fault and the cure is to raise the eye 3-4mm above the rib so the sighting is by focus on the clay sitting on top of or slightly above the bead. A correct comb height see a pattern placement on a sporter 1/3rd below the point of aim and 2/3rds above - putting centre pattern just above the bead in the shooter's perspective.

Gordon R Posted March 3, 2011 Report Share Posted March 3, 2011 I respect your right to disagree. All my guns shoot flat. I do not see the bead when I am shooting. It is a plain fact that if a gun shoots high, you may see more of any target which is rising. It is also a disadvantage when shooting droppers. Shooters would have to shoot extra low. That isn't up for debate. Quote Link to comment Share on other sites More sharing options...
clayman Posted March 4, 2011 Report Share Posted March 4, 2011 (edited) Many people shoot successfully with a flat rib - I have my skeet gun flat, while my trap and sporter's are set high. How-ever, my experience is that at least 1/3rd of shooters benefit from raising the comb and it can make significant differences, often as much as a lift from B to A. Thats not to say it suits every-one, only that the 3mm high setting for a sporter comb is the accepted text book setting for gun fit and is well proven in practice as being the best for the majority of people. Joe Kitson shoots with his eye totally above the comb, several inches, and is a 100 straighter. Conversely, there are also many successful flat set shooters. What you say about droppers is absolutely true, but the degree of change is negligible. For every 3mm (1/8") of extra comb height the pattern centre moves only 4" at 20 yards. This is inside a typical 30" pattern - so if a dropper has accelerated to a full drop ( not just over the stall) and the forward allowance underneath the target is, say 4 ft, 4" one way or the other is unlikely to make any difference to the kill ratio - but an extra 3mm on the comb can make a 10% score improvement in many shooters.
