In the package there was a ballistics chart. Your two favorite dead centers, the 220 grain 50/40 and the 300 grain 50/44 were listed. They used 110 grains of t7 and a 175 yd zero. I am interested why you chose to use the 220's rather that the 300 on your caribou hunt, when the 300's have only about 1/2 inch more drop at 200 yards, they have a 15% higher B.C. and have 20% more energy at 250 yards.
Thank you for the kind comments. Primarily because the .40 / 50 220 grain Dead Center was noticeably the most accurate bullet out of the gun I took-- an Encore 209 x 50.
Phrased a bit differently, the .40 / 50 220 has more velocity and
less resultant time of flight than the .44 / 300 at
all ranges with the same charge, meaning less lead on a moving animal-- and less wind drift out to 150 yards or so. It is also the flatter shooting bullet, allowing for more exact shot placement with no holdover, having a longer maximum point blank range. The nearly 1300 ft. / lbs of kinetic energy left at 200 yards is far more than required to cleanly harvest a caribou.
The main reason, though, was accuracy.
