I've cut a lot of stocks, it is easy, but there are things to think about. I always use a chop saw with a good quality trim blade.
Make sure there are no screws or bolts where you plan to cut.
When you put the stock down flat on the table with cheekpiece against the fence, they often are not level because of the taper in the stock (fatter at butt). If you don't shim the front up so the centerline is level, you get an angled cut.
Adjust the miter angle of the cut in line with the but pad.
I always tape the joint with blue painters tape where I cut to reduce chipping - don't know if it helps, but I've had good results.
Looking for recoil pads (and this is probably the most useful info I have)... download the limbsaver recoil pad catalog. You can match up the newly cut butt with a premade pad for some other firearm that is close. Sure beats grinding a grind to fit pad and having a cushy pad is never a bad thing - even on a 410.
