Lord Geordie Posted August 22, 2012 Author Report Share Posted August 22, 2012 (edited) Comparison between the two. I think a 2mm extension built onto the lee crimp would improve the overall pressure and the asthetic side would benefit too. I think there is a marked improvement between the two as it is or would it be possible to amend the base to raise the cart the desired height? the cart retainer is screwed into place so surely I might be able to have a 2mm seat machined and fit between the retainer and base???

Andy H Posted August 22, 2012 Report Share Posted August 22, 2012 Wax the top of a loaded cartridge and place a coin or washer of the size needed on top with a dab of Araldite rapid on it and lower the ram and secure with a rubber bungee for an hour.

Guest cookoff013 Posted August 22, 2012 Report Share Posted August 22, 2012 crimps should be 0.055" or there abouts, the mec puts a very nice crimp on brand new hulls. my pre-crimp settings were a tad heavy, so i lighened them up. now it crimps just like factory, when before i needed to round off the crimp. i`ve heard if you have 0.080" crimp depth it can help an anaemic cartridge, or make a near maximum pressure load go over pressure. but this was data from the states.

Thats a cheap option I am thinking perhaps a set of bushes for the base in different heights and THIS way you COULD get a LEE load all to do 67.5mm and even 65mm carts I just need to see if I can get someone to help out in the machining world as this will require a milling machine and some light alloy to make the prototypes.
