    7mm Practical sounds alright but I hate rimmed cases and I reckon it looks a bit weird.

    7/375 would be my pick.

    I can / will get a wyats box fitted for a longer magazine.
    @6MMBR I know what I want in terms of performance mate, I'm just smart enough to know what I don't know and defer to those who have already burn't out a few barrels in a big 7mm rig. I have shot goats and wallabies to 1100m mate, just want to go a bit further is all and hopefully its a half moa gun
    Had a 7 lrm and still have two close mates that still run them do about 3k with 180's easily in a 24 inch tube brass is expensive as other than that they're nice I'd go bigger though either 28 nosler or neck down 300 Norma if it was me

    If you want velocity then barrel life will suffer. The smaller capacity cases will give slightly more barrel life. The bigger thing will be how you shoot it. Long strings of shots will eat the barrel faster, no matter what the velocity. Kirby Allen on longrangehunting.com had some good info on barrel life in his 7mm Allen magnum, basically a 338 lapua improved and necked to 7mm.

    I think that you are on the right track with the 7-300 Norma.
    Seems about ideal to push the 195's and will be a great long range hammer!

    I had a 7mm/338 Norma mag improve. Man it had some boogie and hit bloody hard. 180 Berger at 3250. Just make sure you get a good smith to build it for you

    Your getting good speed firing a 7mm projectile from a 338 barrel.

    Cool

    So after a lengthy discussion with my smith and another owner of a 7-300NM (and plenty of encouraging from all of you) I will go with the original concept of a 7-300 Norma.

    Rem 700 Action
    25.5" Bartlein fluted Barrel, T2 brake
    Brass Norma 100X
    Bergers on back order unless I can convince @Kiwi Greg to give me one of his boxes that are squirreled away somewhere...
    Stock.... work in progress but hoping Sendero / HS


    Will post updates on loads and pics when complete...and the load dev story.

    Thanks for the constructive input
