Ted, things have changed somewhat recently, but it used to be that pretty much all the Brit shells you could buy in this country were field loads, not target loads. I can remember when Bill Hanus was hawking Lyalvales. That was before I ever owned a Brit double myself. But he sent me some, and I discovered that they packed quite a wallop on the back end. Shot skeet with a friend who had a Brit double. I handed him a couple of those to try when we were shooting skeet together. He shot one of them, swore, handed me the other one, and told me what I could do with it.
