HI CHET,
I'm glad to see you got the White you've been wanting.
I think you might want to think about toning down your powder load. If your velocity gets too high with those big conicals you may lead your barrel up kind of bad. Some people get better accuracy seating a fiber wad above the powder when using triple 7.
Others with a lot more experience than I will chime in here but IMHO the 80 grains is more on the high end of loads than a low starting point. I have two Whites ond only have been shooting them since late last winter but somewhere between 65 and 75 grains of Triple 7 3f or Goex 3f is what has been working for me. I would love to get some Swiss Powder to try.
