Ken,<BR>Have you ever tinkered with long form gain twist barrels?<BR>I have been tinkering for 2 years now and honestly lack the scientific mindset to wring things out as completely as should be.<BR>I have tinkered with 3 now and own 2 that I'm having fun with.<BR>Some trends that I have noticed may in fact be attributed to something that I have overlooked or ignored.<BR>I'm looking for validation of a few theory's and answers to variables that are kicking my butt in a bad way.<BR>Can you help?<BR>Pat
