Back when I got my first .300 Win mag, about oh... 28 years ago, I was itchin' to try it on something, anything... Loaded up some 130 Speer Hollow Points - and blew varmints to bits with it. Picked up some 150 gr factory ammo at a ridiculously low price and it worked well too. Lots of fun.

Those 130 Speers are an old design, but quite accurate and explosive. Have used them in several .30 cal rifles over the years.
