Your throat length measurement is a good start, but you may want to make a throat impression, too.
There are two popular designs for long rifle bullets, the Loverin and the Bore Rider.
The Loverin is the easiest, just seat it out until it makes contact with something (or more likely, 0.015" away from contact). Normally there is no reason to crimp bolt action cartridges unless the bullets in the magazine are moving under recoil.
The Bore Rider is much more complicated. You'll need to determine your bore diameter (not groove diameter). Then decide whether you want to engrave the nose or if you want a slip fit in the bore. If you want to engrave then the nose should be 0.0005" - 0.0010" larger than bore diameter. If you want a slip fit then the nose should be 0.0005" - 0.0" smaller than bore diameter. As-cast diameters are always subject to tolerances so bore rider molds tend to be a crap shoot.
There are a I dunno if the nose diameters are appropriate for your gun but at least you would know what you are getting.
