Issue with Barnes TSX/TTSX Reloading

Ivan9686

I use Barnes TSX/TTSX 308 150 - 168 grain bullets for reloading both 308 and 30-06 cases. Cases are all trimmed and sized to specification, chamfered and deburred. With the 30-06 cases only, I keep having a problem with the bullet curling a portion of the lip of the case in. It happens with both flat base and boat tail bullets but only with Barnes. This has occurred with new Winchester case and variety of once used cases of various manufactures. There is no noticeable difference in the pressure required to seat the bullet. Any idea of the cause of the cause and a solution beside pull the bullet and throw the case away?

Clean the inside of the seating die especially the nose cavity of the seating stem. Maybe a little more inside champher on the cases. What is the size of your expander ball on the sizing die?

A Lyman M die may help.

Perhaps move die away from shell holder and then lower the seating stem in the die.

Your ram is tight and the shell holder grove in the ram is free of crud allowing the shell holder to seat all the way back.

Thanks for the suggestions. I still find it odd that this only occurs with TSX/TTSX bullets and never happens with other grooved bullets.

Maybe it's the shape Barnes uses compared to the others. I, too need to chamfer the inside of the case mouth just a touch when seating TTSX bullets in .257, .243 and .270 loads.
