You said the rifle likes 180's.Save the time,trouble,and component cost.Shoot a cheap 180 for practice,a good 180 for hunting.Load a pile of ammo with the cheap bullet and learn the load well.Other bullet weights are embelishment.
In a 300 mag for big game hunting,if you cannot get it done with a quality 180,you will likely not get it done with anything else.
I agree.
180's, shoot plenty flat at long range deer, elk, or anything else. Doesn't kick quite as much as 200's or 220's (splitting hairs on recoil, I know, but there is a difference)
Packs plenty of wallop to take anything a 300 WM was intended to take.
If you loaded youself I would say, sure, play around with it........or I may not.
