I have a Six5, and it's all fine and dandy with the 85gr Sierras I'm throwing down the tube, but looking for something with a bit more giddy up. Looking to bounce that barrel and get a 6x6.8 to use 55-60gr to throw some lead at 33-3400. Got all kinds of powder and primers to toy with, so finding a load shouldn't be an issue. Few questions...what twist? 1:9? 1:10? TO barrel? Barrel from Ritch? If I whack a coyote/fox with Vmax or Varminator, will these be prone to exit (not a deciding factor)? Interested in 18" if it makes any difference. Spit some knowledge/experience at me. Yes I have done digging here, trying to think of a reason to not get one.....
