[QUOTE="Grumulkin, post: 518860, member: 29281"] The bullets are key holing because that haven't been stabilized adequately. There are two possible reasons: 1. The twist on your barrel isn't fast enough to stabilized bullets that long. 2. The bullets are going too slow. Actually, barrel twist is a bit more important than velocity. After all, if you have a 1:12 twist barrel, that means that for every 12 inches the bullet travels, it will rotate completely one time. It doesn't matter if the bullet is going 1,000 fps or 3,000 fps, it will still only rotate once for every 12 inches it travels. Increasing bullet velocity will increase bullet RPM though which can help in stabilization. As long as you're not having signs of excess pressure, I would increase the load until: 1. Best accuracy occurs. 2. Signs of excess pressure occur. There is no need to shoot light loads while breaking in a barrel. [/QUOTE]
