Oops I didn't mean bolt head, rather bolt
handle. The model 10's get the larger tactical bolt handle, the model 12's have the standard hunting rifle bolt handle. (And I had a .22-250, so the bolt faces would have been the same size)
I didn't know you could get an unfluted model 12. But it seems plausable. But I don't think you can get a factory fluted barrel on the model 10. Other than that though the differences seem only to be the matte black vs. stainless finishes on the barrel and bolt shaft, and the different barrel lengths. Although I seem to recall seeing a 26-inch barreled model 10, but perhaps I'm mistaken.
Ah, here it is: 10FP-LE1, 20 inch barrel; 10FP-LE2, 26 inch barrel; but all model 12 rifles have 26 inch barrels.
