i squeezed the collet closed a little bit in my vice and then it fit fairly easily...
after i got the thing adjusted it was a piece of cake...
i had some VERY wide spreads on powder charges. i pulled some clips apart and out of 20 rounds i had charges running as high as 52.3g and as low as 43.8g on the first 10 i weighed and then i only had 8 with the same type powder (a short JET BLACK extruded stick ) with 2 rounds that had a very fine black ball powder in the 57g range...
i pulled down 2 boxes of the brown box ammo and it was the same extruded stick and while closer in weights still a 0.7g spread...
this was all LC 68 i had gotten from CMP...
