    I have a question about a couple .30 cal suppressors I own relative to compatibility with 28 Nosler that has a 26" barrel. One suppressor is a newer model 30 CB Ultra 9; and, the other is an older model 30CB9.

    Spec data for the 30 CB Ultra 9 seems to suggest it would be compatible with a 28 Nosler that has a barrel length of 26".

    Spec data for the older 30CB9 seems to suggest it may not be compatible with a 28 Nosler, based on powder volume.

    Question assumes 28 Nosler with 26" barrel and bullets ranging 175gr to 195gr. Assume powder as follows:
    H1000 @ 79.0gr (or less)
    Retumbo @ 82.0gr (or less)
    RL33 @ 88.0gr (or less)

    May I ask for your feedback relative to the compatibility of these two suppressors regarding a 28 Nosler.

    Your 26" barrel will be OK for the 30CB9.

    The Ultra is fine down to 22"
