    Are going to shoot long range or extreme long range? To me, long range is 1200 yards on paper and 600 yards on animals. For that I use a 7-08AI. I can get 2800 fps out of a 20" barrel using Hornady 162 ELDs (M for paper, X for animals). Only 11 mils of come-up for 1200 yards and it is still supersonic for another 200 yards. A lot less powder and recoil for pretty dang good performance.
    If you are talking ELR, then one of the shorter 7mags using 180s are hard to beat.

    7 SAUM is good, what are your goals?, how far LR?, target or hunting or both?

    About 6 or 7 years ago, I had the same dilemma. Wanted to build "my version" of a better rifle than I used in the U.S.M.C. - being the M40-A1. I settled on a 7 Rem. Magnum on a BAT magnum repeater action, Krieger, McMillan, Jewell, etc. If I were to build another 7 mm HUNTING rifle, I'd do a straight 7mm-08 or 280 Remington. You only give up a few hundred FPS, get a standard (or short) action, less muzzle blast, longer life, etc. If it were for targets - I'd do the 300 PRC and forget about 7mm all together.

    I'd at least look into a 7x300 win mag. Some call it a 7 Practical, I believe. Good luck.

    The 7/300 has same neck angle as the 300 Win

    7 Practical has a 30* shoulder

    OP, Alex Wheeler can help you with a 28 Nosler that will be super accurate!

    Good luck!

    Isn't a straight 7mm-08 a .308?

    308 necked down to 7mm

    Well, a straight 284 is a 284 that's not necked down.

    Straight 7mm-08 doesn't make sense because it's a necked down 308.

    I am pretty sure he said it that way because I introduced the 7-08AI to the mix, which is actually a straighter 7-08 than the regular 7-08 when you take body shape into it...

    Maybe "standard" would have been a better term to use, but he used "straight" instead.

    I love the 7 saum
    But I would like to see more people playing with the 7X47AI
    It's good to see what others are getting and doing

    7mm RSAUM or 284, I have RSAUM in both a 26 and 20 inch barrel, both shoot really well. Great hunting and competition round.

    For a long range out west hunting rifle I put together a 7mm Dakota. That cartridge really has a lot going for it as far as OAL and performance, but if I didn't already have brass on hand for it, I wouldn't have built it!

    A long throated 7rem mag is hard to beat when running it on the warm side in ADG brass.
