So thankful to everyone who commented. I will take your suggestions, esp. concerning the reading material mentioned. I will contact Jack to evaluate a 1902 sight base and spring. Very good suggestion about using the mild steel nail as a pivot pin. I am sure I will enjoy shooting this firearm based on it's smooth action and history. Any last comments regarding the Lee reloading dies for Krag? I expect reloading will be the most economical path forward, provided I purchase some ammo initially from one of the few suppliers. Thank you again.
