WinchesterDave Posted February 9, 2016 Report Share Posted February 9, 2016 (edited) Ive never really given the subject much consideration; but what is the purpose of the different widths of rib? 6mm for game 10mm for sporters? I used by B525 Sporter with a 10mil rib on game, is it just personal preference or is there a genuine reason? I've been shooting for 6 years now and would like to know why haha!

JohnfromUK Posted February 9, 2016 Report Share Posted February 9, 2016 I suppose it helps sell guns ...... I've never seen any other clear reason. The Churchill rib is supposed to compensate for the short barrels to which it is customarily fitted. Quote Link to comment Share on other sites More sharing options...
WinchesterDave Posted February 9, 2016 Author Report Share Posted February 9, 2016 Hrmmmm fair enough Quote Link to comment Share on other sites More sharing options...
Bad Monkey Posted February 9, 2016 Report Share Posted February 9, 2016 I've 1 gun with a 10mm rib and 1 with a 6mm rib, aesthetically I prefer 10mm. When shooting I can't actually see the rib. Begs the question, why's it even there? Quote Link to comment Share on other sites More sharing options...
sishyplops Posted February 9, 2016 Report Share Posted February 9, 2016 The 10mm width (and wider ) are to disapate heat better and also sideways so you can see clearly down the rib, it is assumed that you fire more shots with a clay gun therefor generating more heat, weight is also saved by using a 6mm game rib on a field gun Quote Link to comment Share on other sites More sharing options...
Gordon R Posted February 9, 2016 Report Share Posted February 9, 2016 When I shoot my guns, I don't see the rib. I bought a Baikal auto a couple of years ago. All I could see was the narrow rib. Got rid of it after about 10 shells. Quote Link to comment Share on other sites More sharing options...
Crumpler1991 Posted February 9, 2016 Report Share Posted February 9, 2016 I had a 101 broad rib 16mm and really liked it Whats point in a stepd rib? Quote Link to comment Share on other sites More sharing options...
WinchesterDave Posted February 9, 2016 Author Report Share Posted February 9, 2016 (edited) So general consensus.... There isn't a genuine reason... More a sales technique and/or personal preference....16mm bet that looked weird... Not sure but held a High rib gun the other day - you know the ones they all seem to use in the olympics.... Didn't feel normal whatsoever but it was certainly interesting to mount one and I guess you could get used to it I had a 101 broad rib 16mm and really liked it Whats point in a stepd rib? Not sure about raised ribs but when I've held Benellis I did actually like it... Edited February 9, 2016 by WinchesterDave Quote Link to comment Share on other sites More sharing options...
sishyplops Posted February 10, 2016 Report Share Posted February 10, 2016 (edited) There is a genuine reason as per my post, the last thing you want is a heat haze eminating from the barrels, the broad rib is to help disapate this excess heat , many people don't look down the rib, I do, but the heat haze would be there if you looked down it or not , this is why the vast majority of modern guns have ventilated ribs be it wide or narrow Edited February 10, 2016 by sishyplops Quote Link to comment Share on other sites More sharing options...
Gin steady shooter Posted February 10, 2016 Report Share Posted February 10, 2016 I always thought weight was a driving factor, I.e a wider rib, common on clays guns, = heavier gun to absorb recoil. Quote Link to comment Share on other sites More sharing options...
Tim Kelly Posted February 10, 2016 Report Share Posted February 10, 2016 Can't be many situations when heat haze is going to effect you. I suppose if you are pre-mounted it might, but most people are going to be mounting and swinging the gun, so the barrels won't be still long enough to create a heat haze!

JohnfromUK Posted February 10, 2016 Report Share Posted February 10, 2016 Heat haze is a reason often given. In 40 years shooting, sometimes when on a clays flush with very hot barrels I've never had a problem. My guns include s/s and 'game' o/u - which has quite a narrow rib. I agree it may be an issue with pre-mounted, but for me the gun mounting is part of the swing for the shot and I never pre-mount. I can see on a trap gun, where pre-mounting is the norm it might be an issue. Quote Link to comment Share on other sites More sharing options...
