7 mm mag

Nobody is comming over here so I won't get an argument one!

I've owned and used only one 7mm Rem mag. In it I tried just about everything from 115gr Speers to 175gr Noslers. In the end I believed that the best bullet for it for 95% of what I might have used it on was the 160gr. At that thime the only 160gr bullets I was aware of were Speer and Sierra. I had problems with Sierra so Speer it was. Maybe Norma had a 160 back then but were hard to come by.

Still to today I think the 160gr bullet is optimum for the 7mm Rem mag.

As for the 7mm STW, it really brings nothing of value over the standard 7mm Rem mag. but at some 200fps more velocity, I would think premium bullet. The problem comes in at closer ranges and the resulting higher velocities. More velocity puts more strain on the bullet at impact increasing the possibility of bullet failure. I would go with a partition or Barnes X type with it..

160 gr bullets seems to be the optimum weight.
I found my 7mm Rem Mag to be very fussy about ammunition.
A gunsmith told me to shoot Federal 160gr.
I tried lots of stuff and Speer or Nosler Partitions worked well for me.

I've found that you can dial in some loads for a particular range, but the trick is to find one that will perform well, without a lot of fluctuation, over a variety of distances. 160gr works real well from 100yds to about 250 before requiring some aiming adjustment.

Actually here's a bit better news for you. Using the 160gr bullet at 3000fps sight in at just a shade over 3" at 100yds and heres what you should get. You need to live fire to confirm this:

100yds +3.2" 2800fps 2786 ft lbs E
200yds +3.6" 2608fps 2417 ft lbs E
250yds +1.8" 2516fps 2248 ft lbs E
300yds -1.3" 2425fps 2089 ft lbs E

Max point blank zero 281 yds
Max point blank range 328 yds

At 328 yds the bullet will be 4" low. From the muzzle to 328 yds the bullet will never be over 4" high. This was figured from the Nosler handbook using the 160 gr partition and calculated on a Pact cronograph. That is why I told you you need to test it with live fire. But for practical uses it will be damn close.
