RE: Managed-Recoil ??'s
These are carefully developed loads meant to retain accuracy while safely and significantly reducing the recoil through the only means physics allows - lighter bullet weights and lower velocity.
DO NOT EXPECT THEM TO DO WHAT THEY ARE NOT DESIGNED TO DO. These loads will not give you a 300WM that hits like a 300WM but recoils like a 30-06. They will give you a 300WM that performs more like a 30-06 and recoils more like a 30-06.
If you already have a 300WM and the recoil is too much, these are a good way to get back to shooting your gun without a flinch. But if you're buying a new gun, get a 30-06 to begin with.
They're fine for what they are intended for, but go in with realistic expectations.
