I have a rifle chambered in 6mm ppc that I would like to have re-barreled into a 20 ppc. Knowing nothing about it other than I would like to have one. Could you guys help me with that. Need to know neck diameter, barrel length , twist rate and any other thing that you could recommend. I would be shooting 39-40 grain bullets. This will be a long range squirrel gum. Thanks.
