    300g Barnes TSX in 45-70

    I’ve been loading my Marlin 1895 gg with 300g Barnes TSX FN. My current load for it consist of 47.0g H4198. It’s pretty accurate and comfortable to shoot. Not seeing sny ejector marks or smashed primers. But I’ve not been able to find this combo in any manual. Should I be concerned?
