So, I'm shooting my new Miller old Tom, and I just switched to woodies, I'm getting my inward down feather hitting the shelf and wearing them out ( pieces coming off the feathers) the arrow tail is hitting the shelf. My previous carbon beman MFX carbon classic 500 traditionals are not hitting nearly as bad. I did not change the nock position yet, I did try raising the arrow nock above the nock set to get the tail higher off the shelf but it hit worse, right now I'm set about a full quarter inch high nock. If I go above my nock point with the arrow I'm about 1/2 inch tail high. I shoot standard split finger, and I have a nice inline release and elbow position. What do you think the issue might be, the woodies are from Bob at Whispering Winds Arrows and are spined for my bow. They are sweet arrows!
