The only draw back I know of is that factory ammo is hard to come by and on the pricey side of life. That being said a 200 gr speer sitting on 4895 does a really good job. Recoil is stiff because of the 200 gr bullet but not any worse than a 06 pushing a 180 gr. 308 brass necks up really nice and on the 2 I have the brass seems to want to last forever, I pitch it after 10 rounds.
