LEE collet die and the 303 EPP's

As far as i know.. the lee collet die does not touch the shoulder.. i use one when i load my 308 rounds...and it works very well... If these two cartridges are different.. i would make sure the measurement from the top of shoulder is the same.. you may have to adjust the die to account for differences in this measurement..

Only way to know for sure is to try.

If it doesn't work, you shouldn't have any problem unloading the Lee .303 Brit die on the EE; there are enough .303 shooters out there.
