How much over 3000 fps do you need with a 180? I put together a 30" 7 rem mag last year and it shoots the 180 VLD at 3050 @ 60 degrees with 68 gr of RL-25. Recoil is very mild and I know barrel life will be good.

Just a few weeks ago I picked up a used LSS model 700 in 7 RUM. It had a 26" barrel. For the heck of it I tried the 180 Berger VLDs. (The bullets were moly coated) Maxed out with 89 gr for a velocity of 3100 fps. A 28" barrel would give you more velocity but how much I can not say. It will also give you far more recoil.

Another consideration is magazine fit. The 7 RUM with a 180 VLD is one long cartridge. I had a wyatts box mag added to the LSS 7 RUM and still had a .140" jump to the rifling. This rifle shot well with that jump but another might not. The 7 Rem mag has extra room at the end of the mag box and currently the bullet is .035" INTO the rifling. I have lots of room to chase the throat at the barrel wears.

I am certain a few will add to this thread on velocities obtained with the 7 RUM.

Here is one comparison. 180 Berger VLD: G7 BC is .337 Using JBM's program: 4000 ft, 65 degrees:

I am guessing what a 28" 7 rem mag would do 2950 fps

7 RUM ??? ------------------------------------------------------- 3200 fps

Both rifles zeroed at 200 yds

7 rem mag:

100 yd 1.4 high

300 yd -6"

500 yd -33.3

drift in a 90 degree 10 mph crosswind 8.8"

energy at 500 yd 2391 ft/lb

7 RUM:

100 yd 1" high

300 yd -4.9"

500 yd -27.7"

drift in 90 degree 10 mph crosswind 7.8"

energy at 500 yd 2859 ft/lb

Hope this helps.
