After one of my posts about the new Federal #1 Buckshot load, I got an e-mail from a Mr. Trulock, who makes shotgun choke tubes.
He suggested that I might find their products to be interesting, as they had some chokes that would really tighten-up patterns on a shotgun.
I told him I was interested, and he sent me some tubes to test.
I asked for tubes that would fit a Browning Invector Plus, as I had one of those that I could borrow from my buddy Shane.
Here it is.
