    I recently inherited a model 70 in 270wsm. I recently sold a 280ai, and have been kicking myself since. My question is, should I sell 270wsm and look for a LA to build, or convert 270wsm into something like 7wsm or another 7mm flavor?

    Thanks

    Kevin

    I think you would be better off to sell and start with a ling sction. That will help with some feeding issues you may have on the longer bullets of the 7mm. The 280 AI is a very good round. Dan

    I think you should give it to me to make that decision for you!:D I think your on the right track, though don't count the 270WSM out. It seems to be a caliber that defies all odds. I would suggest putting some study time in on the 270WSM before you go changing anything. Just a thought.

    If you inherited it, I woudl keep it. I would even keep it as a .270 WSM (and I am not a fan of anything .277, dont know why).

    If you must ahve a 7mm go for a .284 win on that action, or a 7 SAUM.

    The rifle wasn't inherited from anyone close to me so I have no attachment. I don't want anything in 270 just because I like the bullet options of the 7mm better. I want to do something custom but be somewhat efficient with the round and simplify the reload process to a reasonable task.

    7 SAUM is what you want then.

    +1 on the 7SAUM, I just had a 270 WSM Remy converted to the 7saum and it shoots really well for using a Rem barrel, under 1/2" @100yds.

    My 7WSM will do the same, although it has a Hart pipe on it.

    Either choice should be a good one but if the 270WSM shoots well I don't see any reason to change.

    Yep. This is why I mentioned in another thread to someone who has a 7WSM wanting a 7SAUM that I couldn't understand why such a choice when brass for the SAUM is near extinction.

    My prediction, SAUM brass will be a thing of the past in the next 4-5 years. Even Nosler won't be able to justify continuing its production.

    That was me asking which to go with. Concensous seemed to be the 7saum was better choice over 7wsm.

    Hey Kevin,

    The 7mm SAUM appears to duplicate the performance of the famous 7mm Rem Mag long action on paper. The thing that I discovered (accidentally) with the long action 7mm Rem Mag is that it uses the same magazine length as the 300 Win Mag.

    Fact of the matter is that the 7mm Rem Mag is a shorter case than the 300 Win Mag. This allows you to easily seat long VLD bullets out to the lands and get proper functioning through the magazine. This let me work up loads using Berger 168 VLD's and Barnes 168 LRX and just get some stupid accuracy. (.50 - .90 MOA 5 shot groups)

    I have posted this build here before and even though I have a couple of guns that cost more than double this one, my 7mm Rem Mag is still my "go to" sweetheart hunting rifle. I use it for everything I can afford to hunt on the planet.

    - Rem 700 action (trued)
    - Shilen #5, Select Match, 26" barrel, crowned (no brake)
    - McMillan Hunter stock, pillar/glass bedded
    - McMillan BDL bottom metal
    - Jewel Hunter 1# trigger
    - Swarovski Z5, 3.5x18x44 scope with 4W reticule. Just got it. Awesome.

    No matter what flavor you decide on, you will have an awesome rifle at the end of the day as long as you are patient and whoever does the work is competent. Speaking of patience; all the barrel manufacturers are 8 months out, McMillan takes 5 months to build a stock, etc. It took me a year to build the rifle above.

    Have fun with it!

    Cheers,
    Woolly
