DaveChandler, I use the same sabot and the same Hornady XTP 300gthat Underclocked does. They are great for practice, some use them for hunting, I use Nosler Partitions 300g for hunting because the Hornady tends to separate the jacket from the bullet producing less penetration. The economics are important, because you have to get comfortable with your ML gun, if you shoot $1 bullets you will NOT get comfortable with your gun. So buy some Hornady, sight in with them, shoot a lot with them and then go over to your hunting bullet about 2 months before ML season or you can do what I do I buy 300g Hornady XTPs and 300g Gold Dot and 300g Nosler Partitions and they all group about the same in my rifles so I tend to use the Hornady and Gold Dot for paractice and the Noslers for hunting. I also will after this season switch over to Gold Dot for hunting and just shoot Gold Dot out of my Knight Disc, my TC Omega and my TC 1:48 FL. I use the 300g because they have more down range energy and shoot thru the deer for an excellent blood trail, 240g and 250g do NOT shoot thru the deer based on my experience. Chap
