These days I exclusively shoot 26-inch barrels.
I shoot clays to improve my hunting marksmanship as well as for enjoyment. I haven’t ever shot a registered target.
I have [old] 20 gauge O/U’s with both 28-inch and 26 barrels. I shoot better with the 26-inchers. This may be due to the fact that they’re choked IC/MOD (as opposed to FULL/MOD).
Strangely, I also break more clays with the 20 gauge 26 than with my 12 gauge 28 inch SKT/SKT guns.
My belief, heretical though it may be, is that I just need to shoot one gun really, really well. That one gun also needs to fit me as close to perfectly as possible.
This gun happens to be a field model and is just over 6 pounds. The weight really helps in the field, and I don’t mind the recoil when shooting clays.
My observation is that the gun I shoot well also has a great sight picture (which I think is correlated to the stock, rib, and bead(s) dimension).
Nobody may ever want to buy the gun, due to the barrels, but my son will enjoy it, just like I am now with my father’s old 26-inch gun 🙂
