Just finished a 40 caliber rifle with a 5/16" ramrod. Forgot to tell Pecatonica about the ramrod and they sent a stock with a 3/8" hole. No big problem since I was thinning the fore end a lot, and figured the 5/16" thimbles would hold the rod anyway. As luck would have it, I ended up with the straightest ramrod blank I have ever had, and it doesn't want to stay put. Any good ideas on how to apply a little tension to hold it in place a little better ?
