Here is a handy dandy recoil estimator already initialized for a Grendel load. This link takes you to the instruction page. You can go from there to the calculator proper: Velocity Estimator.
You will need to click on the "Calculate Recoil" after you've entered the data relevant to your interest.
BTW, a mention of acceleration was made in an earlier post. The utility here gives the distance traveled while the bullet is in the bore and the time taken to depart. FRom this one can calculate a = 2*L/(t*t) where a is the acceleration in ft/(sec*sec), L is the barrel length minus about 1.25" (about where the base of the bullet starts) and t is the time.
