In picture number 39 at the following link regarding an 1886 rifle on auction at GB, there are some cuts to the lower part of the barrel that go past the rim of the chamber. Is this standard for this model rifle? The reason I ask has to do with gathering information about the Burgess and Whitney-Kennedy large caliber rifles that also have cuts in the same general area.

The milling (2 cuts) at the bottom of the barrel are where the two protruding legs (for lack of a better word) at the base of the bolt (below where the ejector is seated) engages the barrel when the bolt is closed. Found on the 1886. The 1892 has the same milling cuts at the base of the barrel but the two protruding “legs” are incorporated into the ejector face and not the base of the bolt.

1892takedown,
Thank you very much for taking the time to post the picture and answer my question! The picture allows me to see the difference in the position of the “legs” on the ’86 and my Kennedys, where the “legs” are situated lower, so that when the bolt is closed they make contact with the barrel farther forward than where the bolt face makes contact with the chamber.

Yes thanks Chris and James …I am interested in this issue also. I just looked at 2 , 92’s in 44 they have the clearance cuts , but dont extend thru the rim area like the GB 86 pic . Looked at a 92 in 32-20 , the legs dont protrude as much , so not requiring any clearance in the barrel face, but I could see the witness marks where they touch the flat barrel face. Pushing the back of the cartridge head up the feed ramp as the bolt travels toward closure must be different with these 2 cals as per the diffferent configuration I will check 25-20 and 38-40 tommoro
James ; Just checked the 32 & 44 W-K barrel faces . No clearance cuts at all other than the standard 12 o’clock position clearance for the extracter

Thanks to you both for the added information.
It looks to me like the cuts have something to do with “…if a cartridge case ruptured, the gas pressure would escape out the hole without damaging the rifle or shooter.” (Re: Questions and Answers Page #1395 at http://oldguns.net/q&a8_98.htm . For example, on the small caliber W-Ks, the gas escape hole is located at the forward edge of the top cover, just above where the extractor engages the top part of the barrel, similar to what Spangler notes in the referenced answer, but on the large caliber W-Ks, this gas relief feature on the top cover has been eliminated, and the cuts to one degree or the other on the bottom edge of the barrel that has been cut to allow for a larger cartridge extend a fraction past the rim of the chamber, and might serve the same purpose.
