The Sierra Blitzking in 55 gr. works well for me in my 1 in 9.
You should be able to reach out with a 115 gr. no problem.

It should stabilize any bullet made. I think ther are 115 gr. available from
Berger. I'm thinking looooong range plinking here. I'm curious to see if a
55 gr. bullet would fly apart at 4000 fps.
