WWhat 300 Win Mag Ammo???

Re: WWhat 300 Win Mag Ammo???

I have run both 190gr and 220gr Sierra Match Kings in mine, both work great. It's a 1:10 twist also. I think some others are running the 208 AMAX, but I've not tried it.

The 220 will probably outperform the lighter bullets at longer ranges.
