It is mentionned before, but look at all the police depts. who are using all the Rem. 700 variant. Never seen one using a Savage.
This is similar to security companies using major suppliers that they have always used, even though sevice and prices leave alot to be desired
All the armourers are trained on Rem 700s and 870s. Now I assume they have no problem working on Savages but, without major issues, why change?
