Hi Group,
Figured I would share some data.
Shooting a Knight Ultralight. Using 63 grains blackhorn 209 weighed with Winchester W209 primer. Bullet and sabot are Barnes 250 grain TMZ with yellow supplied sabot.
Three rounds fired. Average 1666 FPS
Temp 56 F Pressure 30.02 inHg
1 1636 fps
2 1681 fps
3 1683 fps
The shots group well with a cold barrel, but open up a lot with a warm barrel. I figured that this load should have been right around 1800 fps. I am glad I checked. This will be my hunting load this year along with my omega x7 using 63 grains black horn 209, winchester primers, blue sabots and 200 grain .40 SST.
Anyone have any chronograph data for an ultralight?
Thanks
Dave
