LOL My 24 " 30-06 will Shoot 150 gr ers all day long at a EASY 3050 fps ! My 24 " 7 MM RM only does a 100 fps FASTER ! RJ
7mm rem mag vs 30-06
- Thread starter 0357
- Start date
Actually Remington stole the idea of a 7 Magnum from another fellow on a old boys hunt with Rem executives AKA 7mm Mashburn magnum.There biggest difference between 7mm Rem mag and 30-06 is that Remiington spent a lot more money on marketing to build the 7mm mystique....
There isn't really a great difference using bullets of similar weight. They have about the same real world capabilities, on paper the 7Rem has a bit better reach and the '06 being better with heavy bullets.

Using a Nosler Ballistic Tip in either cartridge, that 100 fps muzzle velocity gap at the muzzle has grown to 175 fps at only 400 yards. Difference could even be larger , 7mm 150gr ELD-X vs 30 cal 150gr Interlock SP (463 fps gap @ 400y)
I don't think I have ever heard someone compare the 30-06 to a 7rm and determine that the 7rm was the more versatile of the two. I am curious to hear your rationale for this statement, if you care to expand.
Not being a dink, I am genuinely curious.
Mike.
EDIT:
I have taken game with both, I like the 7rm, but love the old war horse.

Ballistics compared for AB LR bullets using Nosler data, 7mm 175gr vs. 30 caliber 190gr. Not a huge difference, the 7mm RM has about 220 ft-lbs energy over the 30-06 at 300 yards owing to the higher ballistic coefficient 7mm bullet.
Of the 2 for heavy game my preference is the 30-06 because it's a wider bullet having 18% more cross-sectional area and bullet weights up to 240gr are available.

When looking at a first rifle in 1965, the 7mm RM was the new kid on the block.
For reloaders there were three times as many .308 bullets versus 7mm.
Don't recall ballistic coefficient being discussed and only the gun writers talked about velocities achieved.
Bought the 30-06 and started reloading and reloaded everything from 110 - 220 (for a planned grizzly hunt that never happened)grain bullets.
IIRC Lake City (could have been Match) was being bought for $2.00 for 20 so every time there was $2.00 in my jeans a box was purchased.
Over time 110, 125, 130, 150, 165, 168, 180 and 220 grain bullets were used. CIL was the only manufacturer selling bullets packaged in 50's.
Around 1500 rounds the accuracy started to fade so the 22" barrel was swapped for a spin off 24" and then given to my son.

Exactly - not enough difference to spit at.
Yeah, but it's funny how that only happened to the 7rem mag, isn't it?
When the 7remmag came out ballistics labs were scarce and nsome of the published load data was remarkable indeed. As the shooting industry acquired better gear and started to measure pressure in the 70s and 80s it's funny how they backed off some of that load data. You can make the 30-06 go faster if you load it to 70.000 psi too.
A 7 mag will kill anything a 3006 will, at slightly longer ranges with a slightly flatter trajectory. Within 300 yards their capability is the same, past 300yds the 7mag is better by virtue of less drop and higher retained energy with typical bullet weights.
At what range will the 7mm rem mag still "kill" but the 30-06 has become incapable of doing so?
No reasonable hunting range. The 7mag makes it easier to hit at longer ranges though, due to less drop and wind drift.
My POINT being is and im NOT a big 30-06 Fan BUT its not near as WIMPY as a LOT of people think it is ! jmo RJ

I think it comes down to the extra shine that belt has at the bottom of the case, much more appealing.

I have seen moose downed with authority at 400yds with the 7mm Rem Mag, and I had a 338WM myself at the time, but I've outgrown magnumitise I guess. Some day I may own another, but for now, at least on the Eastern side of the continent, I see no real need. If I feel it's too far, I'll get closer, or I won't shoot.
Everybody seems to be comparing bullets of similar weight. It would be fairer to compare bullets of similar sectional density. A 180/30 would be the equivalent of a 154/7mm. A 150/30 ( s.d. .226) would shed velocity faster and be more susceptible to wind than a 150/7mm (s.d. .266) assuming both bullets were of like construction and profile. A 175/7mm (s.d. .310) should be rightly compared to a 200/.30.
Almost the same in every category really. I think where the 7RM has an advantage is with a lighter well constructed bullet (eg. a 145 gr LRX) stoutly loaded will give good performance for long range shooting, like in sheep or goat country. But there are lots of hunters who have taken sheep/goat with an -06 as well. My 2 cents...
The reason we don't compare similar SD is two fold - first, if you do, velocity is so different it's hard to make meaningful comparisons. Second, those weights are used for the same purposes - most people will pick a 160 or 175 in the 7mag for moose, while most 3006 shooters would pick a 180. Same can be said for lighter game and bullets (140 7mm and 150 or 165gr 30cal for deer ect)
If you look at the numbers posted by Todd, a 160 accubond has more velocity at 400 than a 140 tsx driven 150 fps faster at the muzzle. Therefore, I would argue a mid weight high bc bullet, like the 160 accubond, might be the best option around for general purpose 7mm mag usage. Faster muzzle velocity than a 175 but BCs high enough to hold onto that velocity.
