7 Rem Mag build

[quaticman]

I am considering building a bolt action rifle chambered in 7 Rem Mag. I want to push the Berger 180 VLD's to at least 3,000 fps. What is the optimum barrel length for the 7 Mag? Will a 30" tube along with a healthy dose of Reloader 33 get me close?

I think I'd want a 7 STW to get that bullet to those speeds with little hassle. - dan

5 feet.

Why not 7mm RUM? That should do the trick.

The 7RM will work very nicely with the 180's... 26 to 28" barrel is plenty.

The 180gr VLD's flies best in the sub 3000fps speeds so there isn't a huge need to go warp 11.

Working on one for a customer right now.. should be a great set up out to 1 mile and more.

Built one a year or so ago, with both advice and a barrel from Jerry. Old 700 action that was accurized, 28" SS match grade barrel, bedded into a B & C fully adjustable stock. When it comes to long range, if Jerry offers some advice - take it.

I couldn't get 162's over 2950 out of a 24" tube. I would just go with a 26-28" barrel and go after precision rather than velocity

28 nosler will be your huckleberry!!

Agree on the 7mm STW

 

[hometownhero]

26" will get you to 3000.

26" will get you to 3000.

7 RMag with a a 26 " will NEVER push a 180 gr to 3000 fps or faster ! I ve had lots of them and NOT one would get close to 3000 fps ! But
my 7 -300 WBee or my 7 STW will ! RJ

 

[rjf1963]

My 700 STW 26" pushes Berger VLD 180's to north of 3000

 

[dan belisle]

Unless you happen to have a very fast barrel, my personal experience with 7 RM is that you will be exceeding safe pressures to get those speeds with that bullet. FWIW. - dan

Jerry in your opinion what is the optimum twist rate for the 7 Rem Mag with the 180 class bullets? I am leaning towards 1:8.5" twist.

 

[Mystic Precision]

For the Bergers, 9 twist is ideal

Im running a 7-300wsm with 180 hybrids on a rem 700 long action with a 29" barrel. I'm getting 2950fps with reloader 25 without a problem had it up at 3000 but it shot better at 2950.

 

[Dogleg]

The 7-300 Win will do it at an idle, and is relatively painless as wildcats go. The STW is a sentimental favorite of mine for what must be getting close to 30 years now, and the 28 Nosler is a better STW than the STW is. 1-9 will do it, but I haven't found a downside to 1-8s.

There is the 28 Nosler?

Also there is various 7mm Wildcats based off "new" Norma Mag that will push 180 to 3200.

I'd run a 28" if it were me. My brother has a Model 70 in 7RM wearing a 28" barrel built by Rocky Mountain Rifles and set in an A5 stock. It's a shooter.
