The only reason I said that is most of the newer style saboted bullets if you get the 3 inch shells they are the faster loadings, and out of some of the standard rifled barrels your accuracy will be hit and miss with faster loads. I just don't think they can stabilize the bullets at those speeds well enough.

However my buddies 11-87 and anothers 870 with cantilever barrels shoot the 3 inch standard winchesters better than the same slug in the 2 3/4 inch version. They tried them and they just were not as good. I don't know that it has anything to do with the chamber though. I think it has more to do with barrel harmonics myself. I am sure if they played around with different shells they could find a 2 3/4 inch shell that shot just as well if not better. There are too many guys out there shooting the 2 3/4 inch shells for them not to work. Almost every modern shotgun is chambered for 3 inch shells and I bet the best selling slugs are 2 3/4 inchers. I can't say for sure though.

My H&R will shoot 3 inch slugs, but the shell length doesn't seem to have an effect on accuracy. It had more to do with bullet design and speed. It will shoot 3 inch and 2 3/4 inch shells just as accurate if it likes the load. Heck I have shot some 3 dollar rifled slugs that would group a little over an inch for three shots at 100 yards. And my gun seems to like the winchester platinums as well, I got around 1 inch groups with those. And for being a 2 3/4 inch shell they have about the most recoil I have felt. However it does not like the faster loadings. I tried some of the barnes 1900 fps rounds and they would not even group on a sheet of printer paper at 100 yards. They were pretty good at 50, but sucked at 100 yards.

I wish I had the money to try them all. I have tried a pretty decent sampling, but not all of them. There are a few I would like to try yet. Truth be known, I am going to try the federal barnes one ounce loads, and if they group within 2 inches at 100 yards I am going to stick with them. I would really like to try to load a Precision Rifle bullet that I use in my ML into shot shell and use that. I think they would be pretty devastating out of a shotgun. They are simular to the hornady sst's but not jacketed, and they are a boat tail design. Very accurate in my ML out to 150 yards in the 350 gr version. I wouldn't mind trying a 450 grn version in a shotgun.

I think your above post was just typo, I was just messing with you is all.

I have tried a few of the lightfield loads out of my H&R and it didn't like them. They offer a lot of different shells though and I didn't try them all. I used brenneke gold magnums last year because I ran out of money and time for testing. The were not the most accurate, but they were ok and I had them on hand if you know what I mean. I thought a 600 grn slug would do more damage, but I wasn't that impressed to be honest. I am sticking with the better designed controled expansion bullets for now on.
