The 22-250 itself is certainly up to the task of taking Texas deer or any other deer for that matter.

If you are loading your own I would try the Barnes bullets in the same weight range as the ballistic tips you are shooting now. Like the 50 grain X, the 53 grain TSX, or the 53 grain XLC.

If you don't reload then Federal loads the 55 grain TBBC and the 60 grain partition. Connely precision loads the Barnes bullets, the TBBC and the partition. http://www.cpcartridge.com/22-250-V.htm

These listed here are all big game bullets and are designed to be used on big game animals in a .22 caliber centerfire rifle. There is no reason not to use it if you want to.

Even with body shots this cartridge is more than up to the task of deer hunting so long as big game bullets are used. I would not trust a ballistic tip bullet on a deer.
