Thanks. I try first to find the right sabot, because that is critical to good shooting in the Savage.You know if it isloose, it don't shoot for beans. With .458 bullets I try CR, MMP Orange and 3Petal EZ. With .452 bullets I do the MMP12 and MMP24, and crushed rib. I do like the .458 bullets better, they seem tighter. After I get "tightness" with the bullet I want to shoot, I try to find the right load of powder. I think it is about 68 or 69 with the 4198 (Skeeter said that, as have others), so I will shoot 67, 68, and 69. I like shooting 5 shot groups, when I get all 5 within 2" I think that is a good solid group. Like today, the TSX 300g "Flat Point" shot real well with 5744, so I will rename my file to "good load". I will do that also with 66g of 4198. Chap
