Any of the 125 grain lead bullets work very well. They are fast enough for good expansion and deep penetration. If you drop down to the 110 grain, the V-max or varmint style bullets will work ok, and expand easy, but the solid copper options work very well for penetration. I run the 125 grain SST or 125 grain HP versions. They work well for pigs and deer. I am making a huge run of about 4000 rounds late this week and early next week of blk out. I just got in a large shipment of bullets.
