    Recently purchased a very, very low round count Weatherby Accumark.
    Mounted a 4-18x50 Kahles on it and adjusted the trigger down to 2 pounds.
    With 112 gr of Retumbo, Fed mag primers, 168 TTSXs loaded to 3.6 OAL it will put 5 in 3/4" at 100.
    Have tried several 180s with Retumbo, H869 and 50BMG. Results have been poor (2-5")
    Have read that the 200 gr Accubond has a high BC and might be a better choice than the 168TTSX. Thoughts, Experience ?

    Second question involves the muzzle brake. While it is a pussy to shoot with it, wearing double hearing protection while hunting is impractical. I bought a blank end cap (thread protector) but it weighs so much less than the brake it causes harmonics to go south. The TTSX shoot a one bullet wide, 5" high group. Does anyone make an end cap that duplicates the weight of the factory brake?

    Thanks for your help.

    AMAZING all the expert long range hunters and nobody reloads the 30-378.

    Guess I'll have to live with Retumbo, 168 TTSXs and 3/4" MOA.

    Thanks!:D
