I definitely agree with the other guys that a 30 cal is not necessary for deer size critters. The 7mm RUM would be my pick. I have one that shoots the 150 gr BT like a dream at 3375 fps. It is off getting a brake right now but I picked up some 162 gr Hornady A-max bullets to play with when it gets back. This bullet has gotten good reviews here as a long range deer killer and it has a pretty good BC at a listed .625. I would think that 3250 fps would not be a problem out of my 26" tube. If you went with a 28 or 30" tube, you could probably improve significantly on that.
I know where you are coming from on the fast light bullet vs slower high BC heavy bullet. Since you are limiting your range to 600 yds, I would think either approach would work well. A ballistic reticle should work great for holdover and you could either hold off or click for windage. Anything under 400 yds should be a point and shoot if you sight in at 300 yds.
The critters have to win every time, I only have to win once.
I was shooting a 300 RUM and 7MM STW last weekend at the range. The 300 RUM was a sporter barrel and the 7MM STW was a heavy varmint barrel. That 300 RUM kicked the **** out of me and the 7MM STW I could have shot all day and have before.
I am shooting 140 grn Accubonds and 150grn Sierra HPBT and I would and will shoot them out to 600 yards and farther. Just my 2 cents though.

Not that the 300 Ultra is particularly nice on throats, but it is a hell of a better choice than the 7 ultra unless your father in law owns a barrel company. THe 7 ultra holds the record for the most overbore chambering of all time. Just about the time you figure out a load, run a drop test, and go hunt your first season, you will be buying a new barrel. Life's too short to have guns with shorter life!
GG: Who cares if the 7rum burns barrels. It's a hunting rifle. Practice with a .308 and use the 7 for hunting only. I can't imagine somebody not getting 800 rounds out of a 7rum with out pushing it too hard which you don't need to. Most of the wildcats that people shoot on here burn barrels.
Nightforce is a Lightforce company. Same company.
Dont need either one on deer at 600! My next project very simular requirments going with one of the WSM's likely a 270WSM. On this issue I think scope choice is much more important! These guys got me behind a NF with a R2 recticle......WOW! I need about 3-4 more! FACT IS there are alot of cals out there that can handle deer at 600, I found out real quick 600 is now a chipshot with my first NF, no holdover put it behind the right hashmark and squeeze! Things go ding and flop after that!
For me Id take the 300rum if thats our only two choices...
Info for thought: 7MM RUM; Drop in inches at 300 yards based on a 200-yard zero. Keep in mind these are factory rounds; Energy in ft.-lbs 2215, Drop 2.7", Recoil 28.3. does'nt get much flatter than that from factory loads. I've got my own home remedies that do better than that. Yes this is a finicky round to load, but when you find the right ingredients it's nothing short of awsome. As far as being overbore, yes it is, it is suppose to be, as is the 300 RUM. Lazzeroni's 7.21 Firebird is more overbore than the Remington 7MM RUM cartridge, and is the only one that exceeds it in performance as far as fps. As far as accuracy, I get 1/2" MOA out of my factory rifle with my hand loads. one more thing fellas, you can get well over 1000 rounds out of this cartridge before you see spred in groups. 1000 rounds may not sound like much, but for an Ultra Mag it is, and It's more of a hunting caliber anyway.
While both the 7RUM and 300RUM and barrel eating machines you can definantly work up a good load and be able to practice with the gun without roasting the throat
If you take care of the gun, clean it well and dont let it get real hot I would believe you should get at or over 1000rnds of bbl life out of it. My 270AM hand 800rnds down it when i took the bbl off and it is still in pretty dang good shape. the throat shows modest heat cracking but not really all that much
As for which one i would pick, i would lean on the 7mm just cause of the higher BC bullet (160AB and 200gr wildcat)
