I would really like to cross section a variety of them. Some seem to hold together just fine and others lose the jacket.
Sofar ive been brutal on the 250gr SST into a milk jug then 2 wet phone books and not one has failed and all kept 200gr+
The 325gr .458 seems to hold up great too.
The 300gr .451 SST holds up ok but doesnt keep much more weight than the 250gr SST.
The 225gr for 45LC fragments badly at ML speed. Sold by the 100 and fairly accurate though.
The little 200gr for 460 S&W holds up much better.
The 300gr 50cal for 50S&W holds up fine but ive never had a 54cal that could push it to the limit until recently. Sofar its held upto 100gr of JSG from my old Thunderhawk54 and my redneck media.
My new GMB54 and 120gr of BH209 might push it past its limits.
I haven't tried the 225gr for 44mag or the 265gr for 444Marlin but i would bet the 265gr 444 holds up fairly well.
I really want to try the 225gr for 44mag. They are sold by the 100 and would be a great option IF they dont fragment. Most of the others are sold by the 50 pack.
IMO the 325gr .458 sofar appears to be the best of the bunch as far as holding together.
BTW you can get the Harvester Scorpion PT for less and they hold together just as well. Only about $20-21 per 50.
