Jeff,

I was not trying to make a comparison of a core-lokt vs barnes x bullet. I was speaking more along the lines of bullet weights. A 200 gr X bullet will out penetrate a lighter X bullet, same with Nosler PT's etc. My thinking of the origional question of this thread was higher SD bullets may kill better than the lower SD bullets, by giving maximum penetration.

Hope this helps.

Regards,
