Re: Changing Cals
Depends on what you're doing. 30-06 to 280 is just a new barrel. 30-06 to 300 win mag is new barrel, new bolt face, new feed rails and new extractor.
Don't forget new types of powders, primers, bullets, dies, brushes, patches, jags, rod, bore guide, etc....
With the rifle work and new equipment it gets real expensive And time consuming in a hurry.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
