The smith that built my 308 even said that 308 was more accurate than 30-06. That was when I was having a brake installed on my 06. Before I had the 308 built. I said "I can't see how the length of a casing (308 being shorter) could make it more accurate." He sad it does. He offered no feather explanation and I was still of the belief it was so I just said OK.
What Scorch needs is reverse reamer. Place it in the hole turn backwards while removing and the hole gets smaller. You know it has to be true, you're reading on the internet. You can't put anythng on the internet that isn't true.
