Hunter Posted February 17, 2006 Report Share Posted February 17, 2006 Are there any problems with using small cartridges in a large chamber, say 3 or 3.5" chamber size, then use a 2.5" cartridge, wont this effect the pellets, as they will hit the end ridge of the chamber? I geuss its not going to be serious, but will it effect spread etc. Thanks Quote Link to comment Share on other sites More sharing options...
dunganick Posted February 17, 2006 Report Share Posted February 17, 2006 nope its fine, i think (not sure) that the thickness of the cartridge case means the shot collum does not catch the end of the chamber. but i really havent much of a clue technically about chambers i shoot 2.5 inch throug a 3" chamber all the time and i havent died yet, unlike 1 or 2 clays (i cant miss all the time can it ) gemini will probably be your man for the answer to your question Quote Link to comment Share on other sites More sharing options...
Gemini Posted February 18, 2006 Report Share Posted February 18, 2006 (edited) No problems at all with using a 2½” shell in a 3½” chamber. As for the pellets hitting the “the end ridge of the chamber”- forget about it. There isn’t an edge ridge to the chamber, it is a cone shaped lead into the barrel. http://website.lineone.net/~dave.cushman/shotshellloads.html G.M.

Gemini Posted February 18, 2006 Report Share Posted February 18, 2006 forcing cones? I suppose they are forcing cones, although they are really just a constriction into the barrel. Have a look down your chamber and it looks like a sudden step from the chamber into the barrel, but it isn’t really it’s just this ramp. If you want to reduce recoil then you can have this cone lengthened by reaming into a longer cone thus reducing the suddenness of the restriction. It does mean a trip to the proof house afterwards though. G.M. Quote Link to comment Share on other sites More sharing options...
dunganick Posted February 18, 2006 Report Share Posted February 18, 2006 and that you wont have chromed bores any more i would have thought. Quote Link to comment Share on other sites More sharing options...
Hunter Posted February 18, 2006 Author Report Share Posted February 18, 2006 Thanks for the replies makes sense now. I thought this 'cone' would be a sharp metal ridge, not smooth like that. Quote Link to comment Share on other sites More sharing options...
Gemini Posted February 19, 2006 Report Share Posted February 19, 2006 and that you wont have chromed bores any more i would have thought. True Nick, but that also applies to guns that have their chokes altered, so it depends on what you want done and what gun you have. I believe the older Browning’s didn’t have chrome bores anyway and were susceptible to rust if left uncleaned, so they were easier to have a choke or cone alteration. Personally I wouldn’t bother having this work done, but to was quite fashionable a few years ago. G.M. Quote Link to comment Share on other sites More sharing options...
