You soundnt have any problem loading the 200 grain VLD in 30 cal. 7mm mag an 300 win use the same action in a Remington 700. If at some point in time you build a custom rifle
you can get your smith to order a reamer specifacly for the type of bullet you are going to shoot(ie Berger, Amax, etc!) long throat, etc! I still say you will be money ahead to go with a Sendero to start with! Just my input! Hope this helps!!
