Re: sabot or round balls
I have a Hawken with a 1:48 twist and it shoots sabots better than anything. A friend has the same gun and his shoots powerbelts better than sabots, same twist. So get some different bullets and take a trip to the range and see which one yours shoots better.
On another note, be careful with sabots, I have noticed some like the shocky sabots seem to be made for inlines, meaning when I shot deer with them and my inline they performed great, however the same shot from my flinter did not expand at all, not enough speed I guess? In my 50 cal flinter I shoot a hollow point sabot, which expands great.
