At 200 to 300 yds, 1-20 twist, smokeless powder, 32" BC, which is a better bullet for target/silhouette shooting only, a 385 round nose or 500 round nose buller? (Lyman 457124 or 457125) Was told to use the 385 for 300 and less and 500 for longe range 500+ yds. The 500 would be more stable would it not? Need help Thanks beng
