i used to have an a-bolt in .270, but sold it and got the x-bolt instead...i have a model 70 in .300 but the a-bolt was a better fit for me, and i was more comfortable shooting it bc of the aesthetics. I loved the a-bolt.
If i were you id take the browning for a better fit, accuracy and just general aesthetics. but either the model 70 or a-bolt...both are great choices.
