After last season, hunting over a tank (that's Texan for pond) at my buddy's farm, I'm thinking of going with IC/full. I was shooting my Winchester autoloader (M1400) last season with a modified choke, but the danged birds would come straight in so close, I hesitated to squeeze on 'em as the pattern was so dense at that range. There were longer passing shots, but I let a lot of birds fly by I could have dusted with an open choke and I'd swing around and shoot at 'em going away, which is somewhat a low percentage shot. I mean, it was great hunting, but I think I could have used an IC for those close birds.
I was shooting 12 gauge in the Winchester, my new double is a 20 gauge, so I'm thinking the long range barrel should be full. I'll be shooting 7/8 ounce loads. I need to pick up some Win AA to pattern out of it. I just got this little 20 SxS and have only patterned one load in it, cheap Remington heavy dove 1 oz load. It was pretty dense, but had a few dove size holes in the pattern. I think I can get it a little more consistent than that with a quality 7/8 ounce load.
I know there's a difference between skeet/IC and full just from trap shooting. I got on this boat to the Bahamas with the wife once about 15 years ago. They had a trap shoot off the back of the boat for a magnum of French champagne. I think it was 5 bucks for 5 shots or 10 bucks for ten shots, don't remember, but it seems like it was a buck a shot. First time, I didn't do well. I'm used to choked guns. You could fire as many rounds as you wanted. So, I'm sitting there talking to the wife and thinkin', "Ya know, I bet that danged choke is open." I was letting 'em get out there a ways.
So, I went down and stood in line and took another turn. Before the guy loaded it the barrel for the first shot, I asked to see the gun, dug out a dime, and it rattled like a clapper in a bell in the muzzle of the gun. I thought that kid was going to freak when I did that, but I assured him there wan't a problem...
So, "PULL", I shot soon as I got the bead in front of the clay and it dusted 20 yards off the trap, did that every shot, 100%. The rest of the shooters were apparently eastern city liberals because I walked away with the booze and I ain't that good on clays.
Only friggin' clays shoot I ever won, LOL! I think that gun has some of 'em messed up. It was a Remington M870 and I think it probably had a skeet choke in it. You really had to be quick on the bird or it was out of range of that open pattern.
So, yes, I know there is a practical difference in choke pattern density. It's sorta hard to tell, though, between mod/full or IC/mod in the field in practical hunting situations, but I'm thinking IC/Full will give me a real choice next dove season.
