Eh, those Barnes TSX's are pretty good for the most part. But in all honesty, I'm just not a big fan of the mono metal bullets. People are swearing by them but I just don't feel they are needed. Whitetail aren't armor plated. Any well bonded bullet works well on them. Granted in the .243 you want a tougher bullet, especially for close range on a shoulder hit, but I've seen a lot of folks that just can't get the 85gr-95gr TSX's to fly worth diddly out of their .243's. You already know a 100gr will fly well. Give the Interlocks a shot and if they fly well you can bet you will be 100% satisfied by their terminal performance. Not to mention they are quite a bit cheaper than those Barnes.
