I built a southern mountain rifle around 20 years ago from a Pecatonica River kit. I had them cut the ramrod channel. It’s always been a target rifle so I’ve never used the ramrod. I didn’t do a very good job on the gun back then so I gave it a refurb this week using my terrible wood working skills and rebrowning everything. I had to use vise grips to remove the old ramrod (destroying it by the way) because the channel is too tight. I have a synthetic rod now I want to use because I wanna start doing some hunting with this gun. Give me an idea how to open the channel a bit using a method other than a drill lol. Thanks in advance for the replies.
