I have a S&W revolver in 32-20 that shoots Oregon Trail Lasercast 115 gr. fp rounds high. I've tried changing the load and increasing the velocity to lower the point of impact and that worked a little. Now I'm wondering if changing the bullet weight is a better approach. Lee has a mold that throws a 100 gr. bullet and while I haven't cast any bullets in a long while I would be willing to do it again since the quantity needed isn't very high. So does a lighter bullet shoot lower?
