Re: 300 WSM or 325 WSM
I have no less than 20 different bullets on hand for reloading my .325 WSM so bullet selection is definitely not the issue you might believe. The range is from Matchkings to Accubonds, with lots in between as far as bullet weight and styles. Look at Hornady's 8mm lists, you will be surprised.
Not as many as .30's but still pretty impressive selection.
