Has anyone had any experience reloading Barnes TSX or Tipped TSX?

Season is over here, but because I like the cool weather and nobody is at the range, wanted to work up some new loads for my 270 wsm.

My one biggest concern is the rings around the bullets. When getting seating depth to where I want it, from my initial test it might be that the very end of the shell will fall between two of those rings. I am sure when I run it through the seating die that the bullet will be snug. But I just not so sure I like the end of the shell open. And I guess this will not matter..

I am new to reloading and there might be something I am not thinking of. Thoughts from those that have reloaded these…

Thanks.
