Barnes TTSX - problems seating bullet

[S_heron]

I am having some problems seating these bullets in my 30-06 brass. I am using the 168g TTSX in .308 and every time I try to seat the bullet to the recommended COAL of 3.218 the last band on the bullet appears to bind on the brass and crushes it slightly. As a result the round won't chamber as the brass develops creases in it. I have changed my COAL to 3.240 and I am not having this problem and I was wondering if anyone else has had this problem or if there is any reason this is happening? In Barnes load data they list the COAL as 3.218" (max for the 30-06)

Properly trimmed cases?

Necks chamfered on the inside?

check to see if your die is set too low, causing it to crimp the brass before you get your bullet fully seated, this will crush your case. Back off the die then tighten down on your bullet seater to get the correct col

If it feeds ok, why not use a longer OAL? Leading your bullet out of the case a little will only improve accuracy anyways....

Ignore the COL listed in the manual, and start .050" off of the lands.

My money is on this, but the others are right- there's no reason to seat deeper, unless required to feed through the magazine, or for better accuracy.

MY nase necks are properly trimmed and chamfered the problem was with my dies. Thanks for the help!

This is sound advice. Certainly don't try to match a short OAL from a manual if it is giving problems.

OP, the SAAMI max OAL for 30-06 is 3.340", you are not even close to that at the moment.
