What kind of pellet charge are you reloading with for target shells? For trap or sporting clays, I'll use 1 1/8oz with my 12 ga and 7/8oz with my 20ga, but what sort of pellet range do they load the target 10ga shells with? 1 3/4oz is my guess...

I know this question was posted quite a while ago. With the level of traffic in this forum, it doesn't surprise me there are very few responses... In any case, here is my experience: I have a 12ga Montefeltro that I bought back in 2000. Since then I have probably put 5,000-10,000 shells through. A couple weeks ago I was shooting trap with 1oz shells and they were failing to eject from the chamber fully. Not every time, but enough to be annoying. This gun has never, ever failed to eject the spent shell before. It was very COLD that night and I was bundled up pretty good. I figured it was one of three things wrong - 1) A 1-ounce shell has less kick and maybe it wasn't coming back fast enough to push the jector pin back all the way 2) Being inertia operated, it depends on the shooter to be there resisting the recoil. Since I was bundled up, it was not acting correctly. 3) It was cold enough that the action was gumming up, slowing the chamber opening? I found all of these to be very unlikely, especially since this gun had NEVER failed me before. The next trap night I used 1 1/8-ounce shells. I had less ejection problems, but still had a couple. Eliminate the shells from the equation. And it wasn't as cold outside, eliminate possibility 2 and 3. I finally ran some snap caps slowly through the action and here's what I found: The setscrew or rivet (its hard to tell which it is) that holds the ejector assembly in the barrel tang had somehow crept far enough into the breach to flatten into a "D" right on its edge. It was probably being hammered a little by the rim of the shells every time one was fired. Eventually, a sharp edge had formed, which was grabbing the shells as they came backward and before they had a chance to compress the spring behind the ejector pin. The result was, the shell would get kicked a little toward the breech and didn't contact the ejector pin at all. then the shell would not go anywhere. Good thing I wasn't shooting doubles... Cure: I took my dremel and ever so carefully, ground off the intervening sharp edge of the setscrew/rivet so that it was now flush with the barrel tang, and thus shells no longer got hung up. Everything works like new now. I checked the rivet, and I could not get it to budge, so hopefully the problem will not recur...

Curious, and I'm not saying you are wrong, but I read in Wikipedia that the bore diameter of a 12ga is supposed to be 0.729". So is it true that the industry standard bores are actually SMALLER than 12ga? For reference, Wikipedia also gives an equation for calculating bore size based on gauge. Do 10 gauge shells cost a lot more than 12 gauge shells? Who manufactures a 10ga any more?

I just recently bought a Supersport 12ga. I already had a Montefeltro 12ga I bought back in 2000. Out of curiousity, I took the barrel out of my Supersport and slid it into my Montefeltro. Now both guns being Benelli's, I had a hunch this would work... I put the forestock on it and tightened it up and the SuperSport barrel fit PERFECTLY on the Montefeltro receiver. I now had a "Superfeltro"? In any case, I would think that Benelli would make these two barrels distinctly different in that they wouldn't fit at all in the wrong receiver assembly if they WEREN'T compatible (strategic placement of a tab or recess, etc.). My question is: Is this really a safe combination? It seemed to fit perfectly. But I know that in the gun world "seeming" perfect and "being" perfect can mean the difference between being safe and losing your eyesight (or a finger or worse).
