The 50 BMG is a scaled up 30-06. Another piss poor convolution.....give or take.
After reading all of the responses to my OP (some very good opinions BTW) I have decided to build my long range gun based on the 30 06. As a follow up question: what are your opinions on the Remington 700 SPS in 30 06? I know a couple of people who have the SPS Tactical in 308 and they are very happy with their rifles. I have shot the SPS Tactical and thought it was a great rifle for the price, capable of 1/2 MOA groups (I shot one out to 300 yards @ 1/2 MOA). I know the stock is not very good but I can change that out. I consider the 700 SPS a starting point something I can build on.
You're long on opinion but short on reasoning. I'm not disagreeing but would be interested if you had numbers and facts for the comparison rather than unsupported derision. What do you mean by "designed"? For what? How does the design enable superior performance?
German Salazar has won multiple competitions going against the "hot" and "new" cartridges with the "old" and "dusty" 30-06. Now I'm betting he could've won with a 6/6.5/7 mm cartridge, but it goes to show that the 30-06 is still a good choice for competition, it is not the best, but it is a viable cartridge.
Me personally? I'm a 30-06 fanboy, I adore the cartridge.
The 30-06 is good for 175-200fps MORE velocity than an equivalent barrel length 308 for any bullet you put into it. There's something to the fact that 30-06 loads in modern actions, modern bullets, and modern powders have 15gr more propellant in them on average. Where does that extra 15gr of powder go to?
What do you mean by properly use a 30 cal bullet?
Take a look at your 30 cal cartridge. Ask yourself:
- how fast can I shoot 168gn out of it?
- what if that 168 had a .315 G7?
- did my new load improve drop and wind drift VS my current load?
If the answer is "yes" - then your case is much better suited for 7mm; not only you'll improve your external ballistics, but will reduce the recoil as well.
Since BC is the king past PBR, for 30 cal to work better than 7mm - you HAVE to shoot higher BCed bullets. 320+ BC bullets are heavy, and you have to shot them fairy fast, so that initial MV of lighter 7mm doesn't overbear the higher BC of 30s (within intended range that is - BC always wins in the long, sometimes very long run).

30+" 30-06 with a break makes me scratch my head. What's the purpose of YOUR rifles? Heavy bench hunting?
I have six 30-06s myself, 5 are for Vintage matches and one is a light-weight brush shorty (like MontanaMarine's). I also have a few 30" guns - but they are all dedicated F-class rigs.
gonz'...that rifle with a good bullet will get you out to a mile with consistent accuracy.
I'm at 4000' ASL, and I take my 22.5" 30-06 to 1500+ yards with repeatable accuracy. I'm sending 208s at 2720 fps.
Your 30-06 will shoot like a 300 WinMag with a 26" bbl.
Ogonzalez, that reamer work out for ya ?

I just loaded 10 rounds of 190SMK and H4350 in win brass and 210M primers to start with. 53.5 grains.
Can you recommend what you think would be my top end load using this powder bullet combo. Should I increase by .5 grains of powder or perhaps .3 grains until I see pressure?
Increasing charge by .5gr increments would be my choice.
I would use one of each as a pressure test sequence first...
Whenever I venture into unknown charge weight territory, I always do a pressure test sequence first. No pressure test if valid unless it is done in the barrel in question.
You can identify an excess charge in a shorter barrel with the bed sheet test. A bed sheet, spread out ahead of the muzzle, will catch unburned powder kernels.

If one could only have one rifle, a 30-06 with a 10-twist barrel is ideal. In standard loadings it's as docile and as accurate as a .308. Pushed hard, it will almost equal a 300WM.
If comparing reloading, then you have to use powder charges within 5-10gr of the 7mm to get improved performance while still falling short of the belted magnums, saving only a few pennies per round. So as far as I'm concerned, the .30-06 is outdated because it can't fit in a Short Action, and weaker than most Long Action.
The 30-06 is hands down my favorite all around cartridge with the 6.5 Creedmoor being #2.
Start at 600yd and increment out to 1300yd with a 308 against a 30-06 and see when the guys that steadfastly claim the 308 is ballistically equivalent start making excuses for their misses.
The 30-06 has an easy 350-400yd of effective range on a 308, I've used mine to hit targets from a mile away.
I own all 3, 308, 30-06 and 300WM. The 30-06 so nicely balances the pro-con list of the 308 and 300WM that I find it to be an exceptional performer and exceptionally well balanced round.
No reasonable person would intentionally choose to use 308 or 30-06 unless someone tells you to - be it Uncle Sam or specific competition (FTR, CMP, Vintage); remove the "cartridge" requirement and you'll be hard pressed to find anyone running a 308 or 30-06 (Tactical, run-and-gun, F-Open, benchrest etc).
The 7, although more than 10 years senior to the 06, is a much more modern cartridge design with a nice sharp 30 degree shoulder and a medium length case, where the 06 has a gradual, sloping shoulder of what, 17 or 18 degrees? and an additional 6mm in cartridge length for no real gain in performance.

The 1st CF rifle I fired was Dad's old '03'A3 - not an ideal rifle for prairie dogs, but I wish I still had it. When I told him I was going into town to buy a new M70 in 243 Win, he told me to take the '06 along and trade it off, as "There's no reason to have more than one hi-power rifle on the place." That was in '68, and there's a darned sight more than one hi-power here in my office today.
Hadn't played with an '06 for a long, long time, and had only chambered three for customers in the 9yrs I've been doing custom barrel work. But about a month ago, after reading some posts on the '06, I got to looking around the shop, and realized I had all the parts to build myself a fairly nice rifle in .30-'06. So I trued a new M700 LA, chambered a Bartlein 5R 1-11tw sendero contour with a Serengeti reamer, bedded it in a desert camo McM A3-5 purchased off their inventory list, hung a straight shoe Timney trigger on it, along with a steel NF 20 MOA sloped base, and put my oldest Nikon 30mm 4-16x50 tactical scope on it with a set of steel TPS TRS rings, after CeraKoting the bbl'd action, base, & PTG Stealth DBM in FDE. And since I'm used to shooting 6 Dashers, 6 RATs, 6x47s, 6.5x47s, and 260 Imp 30*, I added a Harrell's Precision 4-port tactical brake. Wound up with a rifle weighing just over 13lbs.
I'm still waiting on some Berger 185 Hybrids & Juggernauts to arrive; since all I had in quantity were 155s & S175MKs, I've been shooting the 175s with Data 86, a surplus Czech single base extruded powder that was advertised as having a burn rate between 4350 & 4831. Have been mostly very pleased with the accuracy, but have yet to get any chrono data. Based on come-ups at 600 & 700, I'd guess my velocity is around 2750fps, which according to a couple of you guys should be a fairly mild load in the '06 case. Whatever - the rifle is fun to shoot, and I'm looking forward to getting more experience with it when the weather settles down a bit. We're getting gusts in excess of 45mph today - don't think I'd have much luck keeping the sky screens sitting upright.
ogonzalez 13 I am running 180 grains sierra game kings in mine and ran into pressure signs at 56.5 grains of 4350. Your top end seems reasonable I would probably push it to 56 grains if I was shooting 190's. But that's just my opinion on my gun your test seems reasonable and safe.
I use 57 grains of 4350 in Lapua brass and Federal match primers with both 190VLD's and 190 SMK's
2950 fps in a cold bore. Well, in Florida that's 70 degrees. I'd subtract 50fps per inch of barrel under 28 inches.
I have never been able to get my head around why someone wants/likes shorter barrels... Sure you get decent accuracy out of them but the velocity goes to shit.
I'd shoot 30" barrels if I could fit the gun in a Pelican 1750... I don't use my LR rifles for hunting so I am not carrying them around all day... So why the hell anyone would want anything shorter than a 28" is beyond me.
That being said USUALLY there's a powder out there that will allow you to find that sweet spot even with the longer barrels..
