I tried to get into trap shooting and just didn't like the costs. It also interfered with my pistol shooting. I realized too that I like skeet better because it's a more realistic representation of the shots I will get in hunting situations.
I have a nice Winchester Select trap gun that was a real steal back when Gander Mountain was selling them. All I did was add Browning Midas hand-screw-in-able choke tubes and got a nice little choke tube wallet for them. This allowed me to switch between trap and skeet just by changing the tubes.
This worked out OK until I tried my field gun in skeet after using the heavier Winchester. My son used the Winchester and I used the field gun. The field gun seemed like a whippy little fairy wand and I couldn't hit crossing shots worth a darn. This after shooting 22 and 23 pretty consistently with the heavier gun.
The current state of things is that I'll go to the range once a week when I'm out running errands, and shoot a round or two of skeet and sometimes trap. I enjoy it that way. The cost remains reasonable, I keep my shotgunning skills in a state of maintenance or steady improvement, and that's good enough for me.
