Reloading Manual
Ensuring proper system operation
Before using any Mark 7® equipment you must ensure that your Dillon 650 works perfectly in
manual mode. This includes proper settings for the type of ammunitions you are reloading at
each of the die stations. You must load your perfect ammo in manual mode before installing the
Mark 7® Autodrive on your 650.
There is a delicate interaction between the bullet dropper and the amount of brass flair provided
by powder funnel. A strategy that may be helpful is to remove the bullet feeder leaving just the
bottom portion of the bullet dropper. Loosen the locknut to the powder assembly as well as the
two screws holding the bracket in-place under the powder funnel so that you can readily adjust
the depth of the powder funnel. Run the machine on slow adjusting both dies until you get the
operation you are looking for. You can manually insert bullets into the dropper and single cycle
the machine. Make sure that bullets are not toppling over. If so you may need to increase flair
and/or increase depth of the dropper mechanism. Once you have run several cycles without
issue you can tighten everything up and continue operation.
WARNING – Bullet heads behave differently and in an autodrive setting, small variations
in bullet dimensions have unpredictable results in bullet feeding. Take good care that if
you are getting results you are not expecting like excessive bullet topple, bullets stuck in
the dropper, etc. Check the dimensions of the bullet heads.
Calibration
WARNING – Calibration can only be done when the Mark 7® Autodrive is empty with no
casings in the shell plate. Only after calibration is complete you may start reloading
ammunition
Test Rounds
Once calibration is completed, and you have loaded the shell plate with brass you must take the
first round produced and remove it. Take the next two rounds and check the measurements
with high quality calipers. Adjust dies if necessary and repeat to ensure that setting meet the
specifications that you are loading.
