What rifle are you loading for? It's rare to achieve a kiss with a TTSX/TSX before magazine constraints come into play (most factory rifles).
One other thing, you may have to deal with a compressed load depending on how far in you have to seat the TTSX and what powder you are using. My Sako does well with a COAL of 2.77" and 48.0 grains of TAC and Fed GM210M primers. My son took a nice Black Bear with it this past season.
