I did a little range work yesterday. You all have me convinced to try the Speer Gold Dots / Deep Curls. I also have a a wide range of the Harvester sabots so I did some tinkering.
Knight Disc Extreme Thumbhole
Speer 250 -300's
Various Harvester Sabots
Win 209 Blues
100 grains of BH209
35 Degrees
10:00 Wind at 10-20 mph
Right - 300's with Crushed Rib ( CR)
Left - 250's with CR
Bottom - 300's with long smooth
Top - 250's with short smooth ( only 90 of BH 209 )
Looks like the winner is the top target. I can't wait to stretch it out some and see what we have a 100.
The Lehigh conversion had zero blow back and worked like a charm.
