Well after a bit of chasing, lots of waiting, the Lee Target Model "Zero Error" Reloader turned up this morning. Now for those who might not know these are simple hand and hammer tools:-
Despite the tool being about 40-60 years old it has never been opened. The split is from being jostled about in the postal transit system despite beign well wrapped.
I often see questions about Micrometer Bullet seating well this target model has just that . Of course more expensive straight line hand dies are often used by Bench Rest shooters. This Lee tool from the days of Lee Custom Engineering Co only neck sizes and also neck reams. The instructions say to only ream cases fired in your rifle.
Now the quandry ......................................... do I keep it as is still sealed or do I open it and run a fired case through it and see how it all works?
