I have used alot of custom actions & top factory rifles in the 308 class chamberings , Badger 2008 , Surgeon , Parker Hale M85 , Sako TRG-22 , AI AW etc .
And in a rifle using a 10rd magazine , YOU will not find a better/smoother running bolt action than the AI AW , from 1st to last round out of a 10rd mag , its super smooth , so smooth that MOST 1st time users of the AW , find them selves thinking it has NOT picked up a round , only to find that when the open the bolt they are ejecting a live chamber round , and this is also mentioned in the Users Manual , THATs how smooth they are .
But thats not what you wanted to hear , also there is a lot to be said of buying a rifle that has been built as a single design by the makers ie Factory , buying bits and pieces from different companies and then getting gunsmith to work his magic is not as simple & straight forward as a top end factory rifle /\.
I feel I can comment , because I have custom built rifles using the best compotents , ie Surgeon , Badger 2008 , AI AICS stocks & Bartlein barrels etc , all top end companies , and factory rifles from the top companies , ie AI , Sako etc .
And in hind sight , the best thing would have been ,
1 ) Top factory rifle ( AI ) , if in std calibres
2 ) Top factory rifle ( AI ) , and custom barrel , if in a calibre NOT made by AI .
And believe me , thats hard won info , and info most who are dreaming of a custom build , DONOT what to hear or know .
Just my 2 dollars ,
