[QUOTE="nralifer, post: 2903277, member: 94556"] Actually, what we haven’t discussed is the effect of a tip on expansion. I have seen more than once that other manufacturers promote tips as aiding expansion. Their theory is thst the tip pushes back to aid in hollow point expansion. I’m not at all convinced of that. Barnes, Hornady, and Nosler all make formed all copper bullets with plastic tips. Plastic will shatter on impact, so it is hard to envision a plastic tip aiding in expansion of a hollow point. Our bullets contain aluminum tips which in gel testing, are ejected from the hollow within 1-4” after impact depending upon the impact speed. The lower the impact speed, the longer it takes for the tip to be ejected, delaying the onset of ejection. Removal of the tip will significantly reduce the impact velocity at which the bullet will expand. See photos below. At least in Barnes bullets, their tips shatter on impact. We have seen that occasionally the tip stem will not be cleared from the hollow and obstructs the entering of tissue into the hollow preventing expansion. Thus, our data indicates tips delay the onset of expansion. Aluminum is an excellent tip material in that it will not soften or melt during flight, and the shaft bends rather the breaks, facilitating its ejection from the hollow. See photo #4. Photo #5 simply shows the velocity better of the bullet in photo #3. [/QUOTE]
