52 grain Targex

52 grain Targex any good on deer? This is in a .223 loaded to around 3200 fps.

I have some to try, and if they shoot alright I will load them for wallabies, but if there is an opportunity at deer I would like to be prepared. Do they hold together? Frangible? How much of a big game bullet are we talking.
I have some 55 grain Hornady SP I can always stick with those, but it would be nice to have a load with something locally supplied just in case the yanks invade.

99% sure our man @Tahr rates them very highly
