hey guys been running my t7 for about 6 months now and started playing with idea of neck sizing my 308 lapua brass, so ordered a lee collet die and set up per instruction , stripped first cap right off the die body on first 10 pieces trying to get that 25lb stroke , lee sent a replacement , after 20 pieces it was starting to get to that feeling like cap was going to strip so i backed off , played with again but am wondering how you fellow t7 guys have set your lee collet die. also wondering best place to start as far as case measurement when comparing neck sized brass against full length , curious how tight you guys are squeezing your necks against mandrel . experience is much appreciated
