    Also, don't get me wrong here. I like being the oddball too. Using the RSAUM is definitely a way to stand out from the crowd.

    I don’t see 7 saum being the oddball?
    You can buy 7 saum brass from
    ADG
    Gunwerks
    Bertram
    Nosler
    Norma

    Pretty sure Bertram and Hornady are the only brass options for 7wsm?

    Not trying to argue with you. Just trying to see all sides.

    2699057B-F25C-480D-B552-2F8FE437BCF0.jpeg 61 grains of RL26 gets me 3035fps with the 180 hybrids, ADG brass. 26 inch Broughton barrel. RBROS rifle.
    The rifle is almost boring to shoot because it never gives any issues.
    It’s the rifle I let kids and new comers to long range hunting shoot. It builds confidence quickly. It’s taken a lot of animals in the 5 years I’ve had it

    H4831SC and IMR4350 work the best in mine with 154 gr. SST

    All RUM cartridges are based off of the 404 Jeffrey, and the WSMs, 7.4gr less powder capacity in the 7Saum vs Wsm, but the case design allows nearly the same veoclities, yet with less powder. Longer neck on the saum, allowing more room to seat bullets long and get that billet seated at the neck/shoulder junction. Medium action is sweeeeet spot for the saums in my short experience with it, but people smarter than me steered me in that direction : )

    This has some really good and useful info...

    I agree that the saum is easy to load for. I love mine. Have two barrels. One 24” proof and one 28” heavy steel one. The Saum has quite the following in the F class world.

    That's a beauty! Which scope and what's your total weight?

    How much speed do you think that barrel adds?

    Compared to what?
    Good rule of thumb is 25-35 fps increases per inch of rifle
    This can vary depending on the barrel and manufacturers

    Speeds can be dependent on chamber designs and free bore amounts

    Compared to a non Broughton barrel. They are known to be faster barrels. Is this your first 7saum?

    Yes it’s my first 7 SAUM

    Proof has great barrels also
    Travis has a 22 inch barrel getting 2940 fps with the 180’s
