Need Help!!! 7RM, 7RUM, or 7STW

In the next year or so I plan on building a fast 7mm. I started out wanting a .280 AI, but now I'm thinking about just doing the 7mm mag due to brass availability, price, and a little bit extra speed. Now I'm wondering if I should just go all out with a 7mm STW or 7mm RUM. Is the extra velocity worth the price? Most of my shots will be under 600 yards.

BTW, I already load for the 7mm RM for my dad, so if I went that route, I wouldn't have to purchase a die and accessories. Also, I already have a donor rifle in .30-06 in a Rem 700 (blued action from the early 80's). Do either the STW or RUM need a longer action? I know the bolt will need to be opened up, but other than that, what modifications will need to be made?

I have all of the 7 mags you are talking about at 600 yards the deer won't know the diffrence from the rm mag to the ultra. But if you are like me you start thinking 7mm RM will work but the stw is just a little better on energy then the ultra has just a little more. Go with your gut and shoot the best bc bullet your rifle will will handle .

I had a rem 700 30/06 re-chambered to 7mm mag and love it. I have taken deer out to 638 yards with it, using 162 a-max and 168 berger.

The 7STW will do it "better" , but the loaded rounds may be too long for the magazine, won't be an issue if you single load.
You could also do a two load thing, 160 accubond for close things, (<300 yards), seat to fit magazine and single feed the long range load OR extend the magazine box.

Stu.

I'd go with a 7 rum and shoot 180 bergers out of it.

I'm voting for the 7RUM shooting 150 E-Tips or 160 AB's. Back the charge off a little and save the barrel life and still out rum the RM and STW.

Re: Need Help!!! 7RM, 7RUM, or 7STW

if you're usual max distance is 600 yds, though I like the 7 RUM over the other two, if it were me I'd go with the 7mm RM.

Mostly becaues I'm just dumb enough to not read beyond 7mm on the box tag/label and pick up "Dad's" box of remmys for my rummy.

Plus, your cost will be less as you already have the stuff to load and will have a supply of cartridges if one of you forgets to pack yours. Hey, I've done it......

However, if your dream is big as in you're going to Colorado and your dream distance is 1175 yds and you'll settle for nothing less, and you have a good case of tinkeritus go with the RUM.

But the cost in time and $ may delay that trip to CO a year or two.

Roy is right, for 600 yds the 7RM is all you need... but I just like those RUM cartridges and someday you might think I want to reach farther
