RE: .430 or .452 300 grain XTP
The .452 is the better bullet and the black sabot for the .452s are tougher than the green .430 - plus less succeptible to having flyers.... a common problem with the greenies and high powder volumes.I would suggest the Crush Ribs with the .452s or the new MMP 3 Petal EZ-Load sabots as first choice.I had no luck with the MMP-HPH-24s. There are thinner, but MMP uses a polymer substancethat still makes them more difficult to load than the regular Harvesters in two MLs I tried them with.
