7mm??? Build

[midwesthunter]

Ok was going to build a 6.5 STW. But then I got a good deal on a 7mm barrel that will finish 33". So am debating which to build? Was leaning towards the RUM because barrel length. What other options should I consider building off a R700 action?

I wouldn't go with a RUM. If it were me, I'd have it chambered in either a 7mm/300 Win. or long throated 7mm Remington. The 7mm Rem at 28" with the right chamber can produce mid to high 3000 fps with a 180. If mid 3000 isn't fast enough, you can get up around 3175 fps with a 7mm/300. The beauty of these two is that you never run out of brass options. The 7mm/300 is simply a 300 WM necked down and of course the 7mm Rem is what it is, which is extremely under rated for what the cartridge is actually capable of.

I'm partial to the 7STW, obviously, but Brent is also right . The 7 -300 is also a great option. How much of that barrel do you intend on using? What is the contour?
Also, you may want to consider the 7mm Rogue. It's a little better version of the 7/300. Check it out in, Rifles, Barrels, and Ballistics, under " 7 mm Rogue" . It's a interesting read, and cartridge.

Why not the RUM? Largest case capacity and I entend on using all of the barrel. I kind of three the stw out because its a belted case. Wanted more horse power then the 7mm rem mag. If I went with the rouge I'm stuck with them chamfering my barrel.

33" is begging to be a RUM or a 7mm/338Lapua

7lrm. Len at lrh has a reamer or gunwerks can do it. Not a belted case either.

With 33" you can take advantage of a bigger case than the 375Ruger.
