Prior to your next hunting season, Berger will have their 338 model(s) up and running. I am expecting some for testing in the near future (during the early summer).
Additionally, there are some awfully slick (aerodynamic) rebated boat tail bullets with aluminum tips being produced right here in the USA. I should have some of them tested as well (this spring).
So, the 300 SMK has been the standard for a long time, but some new options (made in the USA) that should be readily available are just around the corner in the next few months.
