Does over boring a 12 gauge shotgun to 10 gauge dimentions really improve shot pattern, distance, and accuracy? Or is someone just pulling my leg?

I have shot some barrels that were over .800 bore but at that bore you need a realy soft wad for them to work well and they don't like real cold weather. They Do shorten the shot string quite a bit and gives a nice flatt dense pattern and pretty soft recoil when they are that big.

Personally a .750 bore IMHO is the practical limit. and is large as you typically see in a target gun. Now I am speeking only of target guns. Skeet, Trap, Sporting etc. I don't deal to much with the performace in the field.

One company that buids 12ga. barrels of the mega bore variety is a company called Money Maker they are pretty popular in the trap comunity.

only the pattern in my experience. about .740 is all that you want to realistically overbore.
