    I recently bought a bunch of reloading goodies, and found some 40S&W reloads using 155gr Starfire JHP bullets. There is no data sheet. I pulled a bullet and don't recognize the powder (it's a ball powder, maybe some type of Winchester). I want to pull all the bullets and reload them in 10mm. What reloading data would be right for this type of bullet? I'm thinking Hornady data, but I would like some expert opinions/advice.
