Re: 7MM or 300 Dakota

With the 7/300 Dakota you should be able to push the 180 Berger's or JLK's around 3100 fps. Plus you utilize the high BC of the 7mm.

You might also research the 300 Jazz, it's a 338 Norma necked to .30 and Improved. It will push a 210 Berger to 3150 with a mild load. I'm looking at this cartridge for my next build, except pushing the 220, 240 SMK, or 210 JLK.

Re: 7MM or 300 Dakota

If your going to be shooting at animals I would go with the .300 Dakota for the extra ft/ lbs of energy at long distances , sure the 7mm has great bc per bullet weight but not a significant difference if shooting the heavier vld s out of either chambering. I had a .300 Dakota that was built on a rem action and it shot lights out. Ibwas able to get 1 inch groups at 300 yards with 190 and 210 vlds the Jlk shot slightly better than the Berger.

Re: 7MM or 300 Dakota

I have a Remington 7mm MAG and I love it..it needs a new Barrel and I plan to go back to the same calibre. It has feen fired well over 5000 rounds and thats about as all she can give me.
But anything that was over at 500 yards was killed or would be inside a 5 inch plate.

Jarhead,
Just for your imformation, the 300 JAZZ will push the 240SMK @ 2900fps pretty easily.

I would not go the Dakota route. I would get a 7 or 300 RUM Sendero for about $1,100 and put a Nightforce on it, unless you already have the action for your build.

Re: 7MM or 300 Dakota

I already have the action sitting here. That was why I was thinking about the Dakota. I don't have enough room to get a RUM in there without compromising the action.

I shoot a 270 amp based on a necked down 7 dakota with an improved shoulder loaded lite it still has almost 1600 ft lbs @ 1000 yards 170 grain bullet. I fill more than comfortable with that on elk @ 1000 yards

Re: 7MM or 300 Dakota

The whole idea here is that I have a standard length action. I could build a 300 Win, 338 win, 358 Norma, 7mm rem/weatherby or maximize the actions potential with the Dakota. I have a 30-06 that I am comfortable with out to 500 or so, and just need some more punch at longer ranges. I am not a believer in bigger bullet makes deader animals. The venerable 45-70 won't kill a cottontail if you don't hit something vital. I am looking for retained energy at long range, something that comes from high B.C and velocity. I can achieve that with one of the Dakota chamberings. I just wanted your thoughts which one would make more sence. Thanks for your opinions and thoughts.
