[QUOTE="CatShooter, post: 138819, member: 7"] [ QUOTE ] Cat shooter, Would it not be posible for the same bullet at the same velocity to have a different BC using different powder primer combinations? I think it is possible, Red primer and red powder is a intesly hot burning combination and as it accelerates the Nosler partition down the barrel it erodes a couple of grains of the exposed lead away, from the rear of the bullet. On the other hand purple primer and powder is a single based ball and does not erode any lead away. It creates the same velocity and pressure in the same barrel with the same bullet. Yet the red primer powder altared the BC of the same bullet. This is an example with a exposed lead base in the bullet. Though it may not exist in all bullets their is always the possibility that under the right conditions, that anything is possible. So may-be this answered your question to Meichel. May-be it does not, either way it seems quite possible to me. [/ QUOTE ] Hundreds of Thousands of military 30-06 FMJ, 7.62 NATO FMJ, and 5.56 NATO FMJ bullets have been recovered from test materials for study. They all have exposed lead bases. There has never been even a hint of melting. When retrieved, they show fresh tool marks. Melting lead does not happen. . [/QUOTE]
