Why are some lead cast bullets slightly heaver, up to 2grains, than the listing on the box? I see this with many manufactures. Also, should I charge the round to the recipe and not worry about the weight difference of the projectile?
It can be due to the amount of lighter metals added in the mix-i.e. tin,antimony,etc.to make the bullet harder will lighten the bullet weight,and less-meaning more on the side of pure lead will make it softer and heavier,also figure in the lubricant in the grease grooves of the bullet will make it heavier!:blink:
