Back into it today. First up was to run a case through with the guts of the die removed. Basically overcooked it and overshot the bump by three thou. Words fail me.
So went full engineer and analysed the press action first. What I found was that the linkage was hitting the timber faceboard on the bench and giving me an inconsistent stop. These presses don’t cam over, they have a hard stop built in, so ripped it off the bench, got out the Makita multi tool, enlarged the cutout, added a tidy galv steel faceplate and remounted the press. Felt better full stroke instantly.
Another thing I noticed was that when die is set up to contact the shell holder, they do not contact when running a case through. Don’t know what that’s about but either way, I jigged around, fine adjusting and managed to achieve a positive result. Ran half a dozen cases through and got consistent sizing and cases chambering nicely.
On my hit list tomorrow is to thread lock the breech lock adapter into the press. Has far too much slop for my liking and I think it’s adding to my issues. It’s a great press, the ram is super smooth, but I have my reservations about the above. Will also consider buying another set of 270 dies at some stage but will probably take up Ryans offer and try a another first.
So, finish running cases through then on to working on bullet seating depth before I prime.
Happy days all, Sidetrack
