You need to stop thinking about your pin float, and the trigger and start to focus on the spot you want to hit. Trust your float, and trust your shot execution and leave them to your subconsious.......easier said than done but that's what you need to change. The reason you experience this with a bow and not a gun is because the gun doesn't float, your likely on a solid rest with no sight picture movement.

If you need a quality trigger that youwon't anticipate or feel creeping, and if you need to have anindex finger trigger I would recommend the Carter Two Shot.It's the only triple sear index finger release thatI know of and will break as clean as the 1.5lb accu-trigger I have on my 10FP in .223. That Carter release will feel like glass breaking.
