Lee 338 lapua mag factory crimp die. - LEE 90745 FACT CRIMP DIE 338 LAPUA

This die performs exactly as described in Lee literature. No cannelure is required to crimp, and case length is not critical. However, the die is large and has a 1 1/4'x12 thread size. This means it will not fit in a press that only accommodates 7/8"x14 thread size. I have only experience with RCBS presses. The die will fit in a single stage Rockchucker press with the 7/8"x14 threaded bushing removed. Removal is not a problem if you have large enough "Stillson" wrench or equivalent. A pipe wrench might work except you risk damaging the flats on the 1 1/4"x14 insert.
