I'll give that a go. It is a Brux bbl. I just set the bullet .015" out or off arbitrarily. thxBefore I went much further I'd load one at 34.5 grains .006" past first touch (into the lands) and check for pressure and velocity. Back off a bit if needed to be around 2950 fps.
If that works I would do 3-shot groups .006" IN, .015" out, and .020" out.
Honestly, I don't think the one shot ladders are particularly useful. Good barrels with a Dasher will probably shoot well at a variety of powder charges.
There are a lot of people who have won a lot of matches with 105-108s moderately in the lands at around 2950 fps. I am presuming you have a quality barrel.
