Glad to help, Z. You want to take it apart and clean the factory grease out of it and re-assemble it with oil or whatever is suitable for the powder you'll be using.
It isn't hard or time consuming. Do it once and you'll have it forever.
When you have it apart, you can remove a considerable amount of the spring, provided you won't be using it for percussion afterwards. Careful to not overheat the spring. do it with gloves on so you can feel when it starts to heat up then cool it off before continuing. Also, no scratches across the spring or it can break on you one day. Any grinding or Dremeling should be done lengthwise.
If you intend to do both, then leave the spring and just back off the adjustment screw in the front of the grip frame some to lighten the spring tension. If it consistently fires all the primers, you have enough tension.
