Help me decide caliber for new build

I have a mule deer hunt coming up this fall and I'm thinking about building a new gun for it. I was set on a 7/300 win mag, but talked to my smith and he said he would just go with a 284. So now I can't make up my mind. I don't have anything for the build yet so I can go to any caliber. I was thinking about the 7mm for the high bc bullets and would plan on running the Berger 180 or the 195 when it comes out. Give me some opinions on what you think would be a good round to go with. Here's a few calipers I already have.
30-378 weatherby mark v
260 lrp savage
25-06 700 bdl
6x47 lapua custom
And some 243's

Thanks in advance

I am building a 284 win right now with a 24" barrel i SHOULD be able to get the 195 berger around 2530 fps max, and 180s at around 2680. But my primary bullet will be the 162 grain A-Max at about 2850 fps. This gun will be used for deer/antelope out to 100 yards. Run the ballistic and decide if these external ballistics meet your needs.

Biggest fail of 2014 so far... http://www.longrangehunting.com/foru...ea-ftf-128972/

My guess on W3P .308 230 Grain Bullet: G1 .740-.755

.280 Ackley Improved 40* gets my vote.

What will the 280 AI move a 180 at?

Re: Help me decide caliber for new build

they are almost ballistic twins, but the 280 A.I. will net you another 50-75 fps. The advantage with the 284 win though is that you are able to seat the 195 berger with the boattail shank junction above where the donut in the case would form and still have about .1" left in the mag of a LA savage 110 weather warrior is my calculations are correct. (they should be fairly close)

Not sure about the 180's.....I will be shooting 160 Accubonds once I get my build under-way. So far it's just a pipe dream.

Re: Help me decide caliber for new build

You def need a 7mm, if the 7/300 Win Mag is what you want go for it, but be ready to buy the reamer. I built a 7 SAUM for myself and had seriously consider the 7/300 but personally I like short actions so.....
Since the 7 SAUM does well at 1000 yd Benchrest I figured it should do well hunting and it will add 100 fps over the 284
