We set ours like Stockdale. I call it poor man's bunker. I shoot International loads, 24 grams of # 7 1/2, a lttle over 1300 fps. Don't wait to shoot the second shell. You know that you missed the first one, pull the trigger again.
We have a 100 target shoot every year that is 25 singles, 25 16 yd wobble, 25 21 yd caps, 25 21 yd wobble. It is well attended, good money in the shoot, and most important a fundraiser for American Comrades military organization. This year it is on April 18 at DeWitt fish & game in central New York. April 19 is an ATA shoot at DeWitt fish & game. There are casinos nearby, it is a great weekend getaway to kick off the shooting season.
1 Continental-22 degrees either side, 48 metres (53 yards) random heights. Shot from an arced layout (our lanes are a bit further apart than US lanes I think).
2 Ball trap-several varieties, some shot from straight layouts, some from arced layouts, sometimes the trap house roof is at ground level, sometimes it isn't. One version is called Automatic Ball Trap (ABT). Targets vary from 62-76 metres (that's 68 to 83 yards). Angles can be as wide as 45 degrees either side. A hard left hander from lane 1 is a real challenge at close to 70 mph.
3 Usually loads are limited to 28g (1oz). No velocity limit.
The closest you can get to shooting bunker without shooting bunker is to have a trap house set below ground. Have the springs set for 76 metres, and set the angles at 45 degrees. Shoot only from lane 3, using 24g loads.
We shoot that every so often .One Club has it set up that U are 10 feet to the left but in line with the house and the machine is about 3 feet above ground .Next station U are closer to the Trap but about 4 feet above ground . Third staition U are 4 feet above the Trap and station 4 and 5 is the mirror image of 1 & 2 . It's always a single and then 2 pairs from each station . The most tricky and hardest shot is a low , 3 or 4 feet above ground screamer from station 3 because U have to shoot down on them . The " experts " do that without a premounted gun
We have access to a private piece of property where the deceased owner built his own skeet field.
We have a battery-powered wobble trap mounted on a steel wagon that my friend picked up at a Tractor Supply store, and this makes it easily mobile.
We usually set it up about 5-6 yards beyond the "center stake" on the skeet field which gives us about 27 yard targets from skeet station #4, and then shoot 25 bird rounds from skeet stations 2-6 shooting 5 shots from each station. Sometimes, even farther. We've also got some extra speed on those targets. Faster than ATA trap targets for sure.
We use 1 oz. reloads of 7 1/2 Lawrence Magnum shot at about 1235fps. and a .o35 choke (full). You would have to see how this loads grinds up those "handicap distance" targets to believe it!
This routine has done more to help improve our over-all shooting of quartering target presentations than I could have ever imagined, which was our goal in doing this to begin with. 16 yard trap targets look like blimps after shooting those babies!
A real challenge, great practice and loads of fun.
Try it from the 27, really fun. Personally, I think all ATA shoots should be changed to a Wobble format at all yardages including variable angles and heights for doubles. I think we would see the winning scores become more reasonable. And lets face it, it would be more like hunting which Trap was developed for in the first place. But, I know I'm shouting in the wind, never happen.
Wobble trap at night, in the snow and at handicap yardages. We do that here in the winter and it is fun and challenging. It really teaches you to focus on the clay. I still think it is some of the best training you can do for your trap game. We all know that when the wind comes up the clays will do some funny things. This helps you to shoot those targets better.
We have a Skrap match (or whatever you call it) every new years day.
Spring wound tighter than Dicks hat band, wobble, shot from the Skeet pad's. One box of shells. You don't advance unless you break a target from the pad your on. Last man standing wins.
