    I haven't purchases a chronograph yet and was curious on what my muzzle velocity will be with this load since none of my reloading books have anything similar to this:

    300 RUM
    26" barrel
    180gr Barnes TTSX
    95 grains Retumbo
    Fed 215 primers
    COAL: 3.625

    Load has no pressure signs and accuracy is .5 MOA. I am thinking it should be around 3300 fps, but am curious if anyone has used a similar load that has velocity documented. Thanks.

    I'm at 92.5g retumbo, same primers, right at 3200fps no pressure signs.
    Remington XCR 300 RUM
    Nosler Brass
    26" barrel
    Bedded action
    Laminate stock
    Tigger @2.5#
    Sub MOA at 200 yds

    You may be over 3300.

    I have a load for a 180 TSX in my RUM. I am running a 27" Lilja barrel. The load is: Nosler Custom Brass, Fed 215GM Mag Primers, 94gr Retumbo, COAL 3.635~ .070" off of rifling. This produced 3385 fps and showed great accuracy potential with a .562" pair at 300 yards (this is not my main load, would need to prove accuracy). ES was 17fps. Hope this helps.
