These are some heads that I have tested that have shown to shoot most like field points under most conditions.
1. wasp boss bullet
2. Rocky Ironhead 100 grn
3. Rocky tradition
4. Slick trick
5. Rocky premier 75 grn
other heads such as Muzzys 100 grn and Magnus stingers have proven very accurate as well but those listed have done well in my tests and have prove very accurate.
