Turret Press Alignment

If you are discovering that your cases are hitting the edge of the dies on the upstroke, determining where the problem is occurring is necessary.

1.  Make sure that the shell holder fits all the way into the ram slot and that there is no dirt or powder to prevent this.  Ensure that the outer diameter of the ram is aligned with the outer diameter of the shell holder.

2. Determine if the case is rocking back after insertion into the shell holder.  This is generally caused by inserting the case near its top instead of at the base.  Perspiration or case lube on your fingers can cause the case to rock back after letting it go.

3.  Rote the shell holder 90 degrees to the the 3 and 9 o'clock position.  This removes the variable of the case being able to rock forward or backward.  If the case now strikes the 3 or 9 o'clock position of the die, the problem lies in case insertion technique.  Be sure to insert the case near it's base.

4.  If after turning the shell holder to the 3 or 9 o'clock position and the case is still striking the front or rear of the die, the press is incorrectly aligned.  While we would be happy to align it for you at no charge, there is a home remedy.

Loosen the three screws that hold the turret ring in place.  There is clearance in the turret ring holes.  It is possible to slightly move the ring towards the front (if your cases are hitting the front of the die) or rear (if your cases are hitting the rear of the die).  Hold it in this position while tightening the bolts.  If you discover that this isn't enough movement to align the ram to the center of a turret hole, it is necessary to use more force.

Remove the turret and loosen the bolts to the turret ring again.  With the ram at its highest position and using a 3/4 by 3/4" piece of hardwood, place one end to the front of the of the ram through the top of the turret ring.  Using a prying action, you are pulling the turret ring to the front of its limit.  Tighten the turret ring bolts while holding this pressure.  If this technique does not work, send the press to us for alignment at no cost.  It would not be in the factory for any more than 48 business hours before being shipped back to you.
