No. This rifle has standard twist (1:9.5 AFIK) and a match chamber. There is a lot of loading information in Gack I and Gack III, as well as some other publications.

"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
