I use them. I like them.

The 165g Hot Cor in the 308 has been great on pigs. I love the 150g Hot Cor in my 270 Win. Used the 130 with good results too.

For some reason though - in this country at least - they've got really pricey. They used to be the cheapest but now they're about 30% more expensive than the equivalent Hornady products.
