lemoyne gave good information. I have a CVA Wolf not a Kodiak. My barrel is shorter but I believe the barrel twist is the same. Here's the following bullets I'ves used with good results, all sabots were the Harvester Crushed Rib

300gr XTP
250 and 300gr Barnes Expander MZ (also packaged as the Kinght Red Hot)

Conicals
Powerbelt 245 and 300gr areo tips
250gr Harvester Sabre Tooths

My CVA shoots all the above very well but I've choosen to use the Barnes hunting because they are all copper and retain their weight good. Plus with the Crushed Rib sabot they load nice.....you don't have to beat them down the barrel.
