Yesterday I spent some time at the range zeroing my S&K Drilling and its 22 Hornet Einstecklauf. After some shooting and fiddling, the Hornet now prints about 1.5" away from the 7mm barrel, and I'm bent on getting it closer. This got me to wondering if there is a "standard" on how close the insert barrel should shoot to the main barrel. Does anyone know if there is a standard, or best practice?

Also, what distance do you normally zero your 22 LR inserts?

Thanks-

John
