It will shoot great in the rifle using your Revolver loads, but will probably not feel smoothly, as the wide nose will hang up in many rifles. An LFN of the same weight, with .450 nose will feed smoothly in the rifle and kill superbly at the 1200 fps revolver speeds. However, optimum kill speed would be about 1350 fps with the smaller meplat of the LFN Accuracy will be about the same as the WFN. Velocity from the rifle will probably be at least 150 fps faster than from the revolver. This when using 296 or H110 or similar burning speed powder. The rifle will not only 'take care of itself from there', it will take care of about anything you shoot it at!
If you want to stick with the 1200 fps speed in your revolver, stay with the WFN, and seat it deeper for the Rifle. Ask for a crimp forward of the bearing surface so you can use it seated deeper in the rifle, then develop special loads for the rifle, which give optimum speed and accuracy. You'll know which is which at a glance, and in a pinch can shoot them interchangably.
