    too low a velocity might be it then.. if it is tumbling it is not being stabilized no matter what twist it is, it is just the physics of the critter.. a stable bullet spins at a fast enough rate to where the gyroscopic forces lock it into a point...

    keyhole is a stabilization problem. usually means the bullet is not spinning fast enough to stabilize. what is your bullet length and barrel twist.. 3.0gr clays sounds like your probably well below 900fps, maybe even around 800fps-850fps give...

    reamer was a home made 4 flute from a piece of drill rod that reamed the cavity to .306in. the cavity grew close to 0.005in during heat treating and after polishing it ended up being .311.. i don't lap the dies as i drill the cavity to within...

    what causes the decrease in accuracy with an unbalance bullet then? while it is true the bullet will rotate along the center of gravity as soon as it leaves the barrel it does not necessarily mean that it is stable in flight as the gyroscopic forces...

    an unbalanced bullet will not stabilize no matter how fast you spin it. if anything it will wobble faster around its center of gravity and the groups will open up even further.. but if you want to get into the older bullets not being as good as...
