With the ease of loading 2 1/2" shells, why even bother trying to shoot 2 3/4" in these fine old guns. I have MEC 600's that were bought off the sale board at ranges for $50 each(16ga and 12ga) that I put short shell kits on plus roll crimpers. I load 3/4 oz target and ITX loads and 1oz NP BB's and 2's for coyotes in the 16ga and skeet, SC, upland and waterfowl loads in the 12ga. I shoot 2 1/2" shells in ALL my 12 and 16ga guns even if they take 2 3/4' it is just easier that way.

I do miss the 1oz B&P High Pheasant loads though.

After the first shot the rest are just noise.
