Thinking about building a 338wsm.

I have a rem factory 270wsm that needs a barrel. I was thinking a 338wsm would make an awesome packing elk rifle. I like the selection of 338 bullets and it seems like they are always coming out with new ones compared to a 325wsm.
Thinking 338 barrel in #4 or #3 contour finished around 25" and possibly with a brake. I currently have a B&C Alaskan stock that I like alot and is fairly light.
I bet a 225 accubond, sst, tsx would make a nice elk round.
Anyone ever make one? what velocity might I expect from a 25" barrel and 225 grain bullets. Any opinions.
Thanks

    Although I haven't shot them, I know of 2 of them that are (to quote the owners) "the best elk rifle I own"

    Consider the 225 grain cutting edge bullet at .64 bc. It would do well in that cartridge and make a great elk pack rifle.

    Thank you LTLR, what kind of reports have you been hearing on elk kills with that cutting edge bullet? What powder would you try?
    Thanks

    Re: Thinking about building a 338wsm.

    Look at the 338 RCM. It is just a 338wsn and does not require a custom reamer and die set.

    Hornady and Ruger teamed up to build a WSM that uses the .338 bullets instead of the .323
    (8 mm) bullets of the 325 wsm.

    The Hornady Superformance ammo is loaded near max and produces 2950 ft/sec from a
    200 grain and 3864 ft/lbs energy. they also load a 225 that is slightly slower.

    The RCM stands for Ruger Compact Magnum.

    At least someone was listening, the wildcaters have been opening the 325 wsm up to .338
    and they just made it a standard cartrige.

    Ammo is about $42.00 compared to $60.00+ for the 325wsm.

    I have built one for myself and another is in the works. Both are built on the Rem Mod 7 .
    Do a search on 338 RCM and there is a thread talking about it.

    Hornady makes the dies and PT&G made the reamer.

    This is a powerful little round and is considered an equal to the 338 Win Mag.

    Just a thought.

    Re: Thinking about building a 338wsm.

    Me and friends have taken several animals this year with the cutting edge with excellent results so far. Good enough that I have retooled everything to that bullet. I got as high as .65's bc out of my 338-378 wby by pushing it to over 3500 fps. Windage was within 1" at 1200 yards of the 300 smk loads I was shooting according to jbm. In other words I can't shoot good enough at 1200 yards to tell the difference in windage but the trajectory is way better allowing my clicks and ballistic reticles to cover far greater distances. Recoil is way more pleasant since I shoot light hunting rifles. I think this bullet and the 252 grain .72 bc will help make these size 338's shine and ad a new bullet to the big 338's for people who do most all their shooting inside 1200 yards. The 252 grain bullet is good as far as a guy wants to shoot. Specialty bullets are pricey but not as costly as missed opportunities on hunts.

    The first powder I would try would be H-414. In many tests the past two years with smaller capacity 338 caliber cases H-414 performed the best.

    My brother-in-law a couple years ago put a Mullie to sleep in its bed at 1400yds with one shot using the 252grn Cutting Edge bullet. Didn't even twitch.
