"...a .244, not a 6mm Remington..." The two are exactly the same thing. Difference is just the name. http://stevespages.com/jpg/cd6remington.jpg
Your 1 in 14" twist will prefer lighter bullets. Fortunately, there are lighter 'deer' bullets available these days. Assuming you want to hunt deer. That Sierra bullet should do nicely, but you have to work up the load for your rifle. Most current 6mm's have much faster twists.
Between IMR4350 and RL19, the IMR gives slightly higher velocities with 85 grain bullets while using slightly less powder. Not by much though. Max loads are different by 3.5 grains of powder and a whole 66 FPS.
