    I see that this cartridge seems to be getting just a bit more "available" in factory offerings of rifles

    it has always caught my eye, but I've never dove in yet

    Brass--is it just Hornady and Nosler? or is there another good source of brass?
    Factory ammo- still seems like not very many offerings and pretty pricey, but that doesn't concern me too much as I reload (though it is nice to have decent priced factory ammo to shoot for brass in the beginning)
    Fire-forming--I have limited time, so I don't care to spend my time fire-forming cases, so "full size brass" cases are a must
    velocity-- if you have one, what are you velocities from a 24" barrel?

    any thing else about this cartridge I should consider?

    Hornady and Nosler are it and not very good choices IMO. I have been encouraging people to call or email ADG to make A.I. and Sherman brass at the same time. This would fatten their sales if done together and benefit both groups!

    Tagging in. Building a 280 AI now and planning a 24" barrel.

    I get 2975fps from a 175 Berger Elite w. RL23. Accuracy is awesome too. Works well from 14° to 100°+.

    Exactly the bullet I want to run. What length barrel?

    2980 with 168s in 24" and rl23.
    Sweet case.
    ADG would be great, Nosler is decent, but will drop primer pockets. Hornady is not an option for me.

    Looks like re23 is the go-to powder for this cartridge
    Looks like speeds are closr to the 7rm

    Hey Lance....the 7ss will run the 175 well over 3000 and the Sherman will outrun the SS! I will loan my reamer to someone if they want to clean up their chamber.

    I agree. Now all you need to do is.produce some factory ammo for them to get the non-reloader into the addiction.

    That's why we all need to call ADG:D

    I know, and I got word my initial order was shipped today!
    Seriously though, the reason we got ADG brass was because enough people asked for it and they knew it performed! The same is possible for the long action Sherman family.
