Saeed,
I am thinking about building a 6.5 STW. I have not found many people who have data or experience with the rouund. Did you do the work on the 6.5 STW that is listed on the reloading pages?
Thanks,
CRoberts

WOW ----- Those speeds are impressive. I shoot a 7mm STW and a .358 STA already and have been casting my eyes for something new, might just consider the 6.5 STW. Good shooting.

You might also consider a 257 Hot Tamale, which is the 7 STW necked down to 257.
