I live 90 miles from where they are made and they do not carry them around here. We have been trying to get them in the 300 size but no luck so far, 250 gr is what they make in the 452, and 458. 110 gr is what I use, and have tested them on water jugs at 100 and 200 yards, and on deer and coyotes, the exit hole on the animals is about the same, about the size of a golf ball.
The bullet that Ron recovered from his test, is the same shape on the pedals as what the 200 yard test I did.

The 250gr GMX is close to the same length as the 325gr FTX so a 300gr GMX would be very long. The alloy is also harder than a solid copper. It more than likely 95% copper and 5% zinc aka guilding metal. Basically the same alloy they use for jackets on the FTX/SST line.



250 Grain GMX

Overall Length 1.076-1.083"
Base to Ogive 0.575"
Ogive to Tip 0.501"


325 Grain FTX

Overall Length 1.102
Base to Ogive 0.601"
Ogive to tip 0.501
