I have a .243 handi barrel that I am thinking of turning into a .260. For those that have done something similar, where is a good place to have the work done and approximately how much did it cost? Is the .243 able to be made into a .260 or will I need to start with a different barrel? I do not currently handload now but am planning on it in the future. What twist rate should a .260 have? I have seen 1 in 8 and 1 in 9 but have not done enough research yet to determine which would be better. I just brainstormed this idea the other day but I already have an XS7Y .243 so this barrel now became a good choice for a project. Thanks for any help.
