Whether you will need to do anything between the powder and the conical will have to be tested on the range.

You can use felt wads, fiber wads, 20 grains of cornmeal, or just shoot them like they come. Start with 70 grains of Triple Se7en 3f or 80 grains of Triple Se7en 2f. See what happens. Whether your encore will shoot conicals will have to be seen. I have read some posts about the QLA causing problems in that department. Good luck with your rifle.
