Which bore size is best for the 6MM??

[Raptor]

For shooting Sierra or Berger bullets which bore size works the best, .236 or .237?? Thanks Guys!!!

My 6mmPPC Krieger barrels all have a bore diameter of .237" and shoot custom made bullets. Krieger recommended the bore diameter when I told them what type of shooting I intended to do. Call your intended barrel manufacturer and ask what they recommend.

I believe that .236" vs .237" issue only has found some definitive roots in short range bench rest with the lighter 6mm bullets. For the bigger bullets I am personally not sure it really matters but I prefer the .236" (although I have a number of .237" barrels that shoot great too).

I like the 237 ...... I also like shooting cleans with a high x count
