We have a complete line up for the 3030. We have 150 and 170 grain pulls from Sierra and Hornady, as well as 120 hammers and 150 maker all copper. We could do anything else you want as well.
The last bear I shot with my 3030 was with a 150 grain power point at 10 yards and strung him end to end 2x with complete pass through. First shot through the heart and out its butt. Second shot through left hip and out the right shoulder.
Nothing special is needed at 3030 velocities. But hammer, maker ,swift and I think Northfork all have tough bullets if you desire.
