Oh forgot to add, you do NOT need "special" magazines unless you like paying for them. Simply buy a follower or 3 for $10-11 each, You can put a 450 follower right over top of a 223 follower and turn a 30 round magazine into a 11 round 450 magazine for $11. OR you can pay 3 times that for a "special magazine".
I have my 450 set up to run 250s to 500 yards Once I get it tweaked in will get a CDS custom dial....
