The hammerhead is a truely amazing barrel. It is extremely accurate do to the rifling on the inside of the bore. It's consist due to the ability to change "fins." It is quiet down range due to reverse porting.
I've used this barrel on a Superstock, DM4, 98 Custom, Angel Speed. And everytime I've used it performs beautifly. When a ball breaks, very rarely, the barrel with clean itself. And although the first few shots go a little crazy, after about 5 shots its back to normal and clean.
I recommend this barrel to anyone who is looking for a truely amazing barrel for the performance.
This barrel is the best barrel I've ever seen on the market today, I recommend to amany a people all who become very pleased with it. It's performance was off the charts on my scale and all I've seen use it! Go out and spend the extra money on the best barrel you can get, its well worth it!
