I haven't torture tested too many or cross sectioned any of the common FTX line up. I have however shot quite a few of the 2 light weight .452s. The smallest 45-200gr FTX is made for 460S&W which is a screamer for a pistol round. Roughly 2300fps is quite possible and they are made for that velocity. Unfortunately i cant get the 45-200gr FTX to group very well in any ML. It is a tough bullet though compared to the 45-225gr version which is made for 45LC lever guns.

A few guys on Dougs have tried them also with similar results including on game. Reviews from 460S&W owners have also been fairly similar too in terms of terminal performance.

In a lever gun a 45-225gr FTX is moving no more than 1300fps in the Hornady ammo at best. Its very fragile compared to any of the others ive shot into a variety of media. We were shooting some for fun in 54x45 sabots with light loads of T7/BH209 for the kids. It seemed to handle the load "ok" with impacts at about 50-80 yards. I have no idea what the MV was but it could not have been too much in the little carbine.

In my NULA i shoot the 225gr FTX for fun because they vaporize water jugs and ive yet to recover more than just shrapnel. Granted mine are REALLY moving in the NULA. They are also highly effective on "varmints" if you don't care about pelt damage. They are cheap too in 100 packs instead of the normal FTX 50 packs. So...for me, that one is just a fun bullet with very few ML hunting applications. I wish they held up better because they are VERY accurate in several of my MLs and recoil is mild.

Leymone, if you like the FTXs, give the .458 325gr a try sometime. Use either the MMP Orange or the Harvester black crushrib. I use the MMP but the HBCR works well too in a loose bore. They work quite well with BH209 speeds.
