Well the end result will look the same at 80 or 90 as it did at 50 (or 100-120). They don't expand, the petals separate and spin out, the core drives through. The fact that they work at 50gr... means they are good to go at any powder choice. The copper vs brass that are currently offered, just allows them to comply with addl state laws.

Great shooting there for sure!

I'll be interested to hear about the performance of the tips....

If we look at the velocities from Grouse's post we see that the 240gr lost over 400fps at 100 yards. Ron's 50gr load is probably not a heckuva lot slower than it would be at roughly 150 yards. More or less its a good representation of how it will react at that distance.

Its pretty safe to assume any load a ML can achieve will not be enough for a controlled fracturing bullet to lose more weight than Ron's test....Obviously its not lead we are talking about or a expanding bullet design.
