Disclamer: I have no experience loading 223!
Do however have experience with them in 308.
Findings:
Forget the tsx get the ttsx.Open faster IE transfer more shock and energy to the animal instead of the (I hope) dirt behind and have a better bc.
If your a neck shot man forget both and stick with a cup and core type pill that will fragment.Yes a barnes will do it but a cup and core will do it better.
Spend the time to test throughly at different jumps to the lands for accuracy,Mine loved 10tho(single feed so completely usless) and 60 tho mag fit plus a bit. In between was so so.
You can and will probably need to run more powder for the same velocity as a traditional type pill of the same weight.
Push em hard! my rifle generally shoots better below max except with these.
As above no experience loading 223 but have a fair amount of experience with the cal on deer.
If it was me id be trying to get 55grs to shoot to get velocity up. Id be very surprised if they failed to exit a red on a broadside shot.
