This should be fun.
1. How many calibers you load for?
2. How many different brands of bullet you got?
3. What brand do you have the most of?
For me...
1. 15 (14 rifle + 9mm)
2. 6 (Hornady, Barnes, Berger, Sierra, Nosler, Speer)
3. Sierra.
I have a make of Sierra in every caliber I load except 338 Win Mag. Close second (Sierra beat em by 1) is Barnes. Match Burners and TTSX. I became a big fan of the TTSXs last year.
