Just as a FYI --- Use a machinest tool called a small hole gage , tbey are inexpensive and adjustable , to measure your bore . Then mic the gage , this is your bore size . Now take a sabot w bullet in it and measure it along the bearing surface (the sides of sabot & bullet assembly) . For best fit and function the bullet sabot combo should be .002 to.003 larger than your bore . THIS is what matters MOST . Anything else is just details of bc , bullet preformance on impact , etc . Oh yea the bullet MUST seat all the way in the sabot no strain no fuss no.pushing the sabot petals open--- nothing . I dont care what the names on the shiney package are . THIS is how its done . It will load with 25 to 35lb of pressure when its right in ANY rifle . Heavy loads may require a base sub and/or a tougher sabot . Same fitment along with roughened up bullet sides so bullet wont spin inside sabot . This is what works .
