The new bolts are Easton carbon raider, and the old ones are no names from an archery store, But they worked well for me. I haven’t had trouble mixing and matching these two bolt types in the past, but of course I’m wary now. I take your point about different bolts and weights and now Nocks, and I intend to be more methodical about it going forward. I’m definitely at a point using a crossbow where I am needing advice, not offering any lol. Appreciate the feedback.
