I picked up a box of the Combined Technologies .22 caliber 55 grain pills for my 22-250 and need some load data. I know these are made by Nosler so I'm wondering if I can just use Nosler's data for their 55 grain balistic tip? One thing that I'm not sure of is that several of my manuals list higher powder charges and higher velocities for coated bullets. Is anybody using these? Any ideas?
Thanks, M70
 
Nosler says to use the same data for CT's BT's as for their NBT's. I have messed with 40 gr. CT BT's and found they shoot quite a bit slower than uncoated 40 gr. NBT's(100-150 fps). You really would have to shoot through a chronograph and see how the velocities compare to book velocities taking into consideration things like barrel length (+ or - 25FPS per an inch. Without a chronograph I would just stick with book data for NBT's.
