bpesteveWhen the barrel(s) of a break-open single or double gun are fitted well at the hinge pin and standing breech, they are said to be 'on face'. As wear occurs in the hinge joint either from abrasion, overloading or just a lot of shooting, the barrels will begin to have a bit of clearance at the standing breech; they become 'off face'. Such a condition, once started, will rapidly accelerate as each round fired will have a running start to slam the barrels away from the standing breech. Repair is usually to build up and refit the hinge, typically a $200-$500 job.

MacD37bpesteve, is very correct in his explanation. However, the "OFF FACE" condition caused by over pressure isn't so easy to fix, sometimes! This is because this OFF FACE CONDITION is off face due to the bending of the barr, and is actually still "ON FACE' at the bottom of the chamber end of the barrels, but OFF FACE at the top of the barrels. This is serious damage, and sometimes is beyond repair! this is why everyone keeps telling you to be very carefull about chamber pressure.

MADDOGSince we are on the subject.... I am looking at getting either a Krieghoff or a Searcy, in 470 NE. In your opinions what will be better, since my knowledge is limited on these type of guns.
MAC; Thanks for the explanation, I do however understand balistics and am willing to stay within the limits of my chosen cal. I fully agree that these calibers have been working for many years and don't need improving. I have many of the new jacked up ultras,Weatherbys and such. But just finished a hunt in texas and used a old family hand me down 30-06 with great success. Thanks for everybodys in put, Please educate me more "Maddog"

AtkinsonI agree with Mac,,,Also I much prefer the Searcy....
You can very easily shoot a double off the face with one shot in many circumstances. A good overload is all that is needed, same with headspace on a bolt gun...
Many English rifles come off the face at about 300 rounds and are still usable for several hundred more rounds..I always sent my gun in every year for whatever adjustment was needed, a phyical check up if you will and if you hunt a lot of dangerous game thats pretty good insurance, not expensive if you do it every year and don't let them wear out before maintence...
I frankly don't believe you can shoot the Searcy off the face with decent loadings..Argueably I belive that came about by steel that tended to wear much more than todays good steel..A searcy with ejectors opens like a English double with extractors, smooth and slick,..English guns wear in and by that process they also wear out, New English ejector guns were tight and hard to break open until until they wore in, for that reason many hunters of yesteryear took the ejectors out and used them as extractor guns. along with some other reasoning that may or may not have been legitamate.
Thats my opine, and its probably argueable...
