Home Forums Hunting & Shooting Ask The Gunwriters 7mm or 300 win mag

You're learnin...just not quite there yet.

Keep on, seriously. I think you are WAY ahead of your time curve. Congrats.

'experienced IS the key'.


BTW - I LIKE & USE both.

That's eaxactly why I no longer engage in these types of discussions on this site.

There is always some genius who comes along and wants to crunch the numbers a different way. State what his handload shoots for his load, and then quote a Hodgon manual for yours.

I've a pretty good idea what both bullets do. If you want to burn more powder and absorb more recoil to achieve the same results, by all means do it.

BTW, my 162s run at 3100fps. 208s at 2950 ish.........

I'm not sure where "there" is.

My experience with both is the basis for my arguments, and I firmly believe that energy is a crap designator in examining ballistics and terminal performance.

There is a pretty considerable difference in a 7mm 180gr VLD and a .30 180gr NBT, even with the 30 starting 150fps faster. I've seen it, and shot both.

My point being- the 7mm offers the most for the least. And 6.5s take that even further.

Good grief. 300's certainly work, but what animals can't be killed neatly with a Partition or TTSX from a 7 RM? There are only a handful on the entire planet.

If you're nervous about tackling it with a 7 RM, you need a DGR.

2much: Well I haven't seen anybody do that....RC is quoting actual velocities for his 300 mag...My 162's are loaded to 3200 or so....and when I used a 300 magnum with 200's it was with a Weatherby at over 3000 fps.About everything I ever killed with the 300 Win Mag has been taken with 180 gr bullets.

My purpose is not to twist data in one direction or another....simply set forth my opinion that the 7mm's ,while good at what they do, are not more potent cartridges in general than 300 magnums...they can't be because they simply don't have the bullet weight and diameter to do so,and propel heavier bullets at the same velocities as the 7mm does lighter ones.

Of course they kick more...that only makes sense; but that's a personal thing and it's up to the driver to determine how much recoil he can manage.

Well, Bob, I did see somebody do that. And if you read it again, you will too. Actual velocities for his rig, slowa$$ book velocities for the 7mm.

I'm goin' huntin' you kids enjoy...........

BTW, Bob, my response wasn't aimed at you but this thread in general.

The difference there isn't the BC, but the price. It's hard on the pocket book to put thousands of rounds down range every year when the bullets cost twice as much.



Perhaps in the USA, Bob Most of the world doesn't hold the same fanatical zeal for .308" that the US holds...

If the difference between 7mm and .30 has to count for something, then the same can be said for the difference between .270 and 7mm The extra 20-30 grains of bullet weight and larger expanded frontal area count for something, but is it enough to notice a marked difference in the field when metal meets flesh? Guys like JB and Dober don't seem to think that the difference in terminal effect between .30 and 7mm is enough to worry about in practicality. I believe the same goes for .270 bullets vs 7mm. The trouble isn't killing once the bullet hits game, but steering it through the wind and weather conditions to hit the mark

I'm so firmly opinionated on the difference between 7mm and .300 magnums that I own three of each.

I have both an like both, but my fav. is the .30 cal.. One of my mentors was a 300 man much of his life, but after age 70 he mostly shot a 7mm Rem..

Answer: where exterior ballisitics are concerned, they are equal

Might want to recheck those numbers, Rick...

Never really paid attention to lighter game, but game over say 1000 pounds. Between the 7 Rem 7 STW and the 300 Win the 300 is better at the heavy lifting.And yes own all 3 killed many animals over 1000 pounds with all 3.

They are both great rounds and I wouldn't hesitate to use my 7mm's for any game that walks in British Columbia.

Already did and saw that I goofed. Ya gotta put in the correct atmosphere!

10 more lashes with some Angel Hair!

Well, not all of us are high rolling big-timers.

I would be thinking lightweight for sure. A Kimber Montana 300wsm with a good hunting bullet. Maybe a Leupold VX3 2.5-8x36mm. Spend the rest of the money on taxidermy services....:)

Ha! It happens to us all!

Let me SPLAIN it this way.

How many 'years' experience do you have with the 7 & 300 mags?

How many HEAD of B G have you taken with BOTH??

IMO - IMO, you are a FEW yrs. and MUCH B G behind BobNH and his experience and OBSERVATION has more weight.

A 7mm 180 VLD ----APPLES
A 300 180 NBT ----ORANGES

They are NOT shaped (BC) the same. For a VALID comparison for ACCURATE results, the bullets MUST be comparable.

180 vs 180 ain't where it's at: e.g. a 700 HP NASCAR race car and a 700 HP Mack truck ARE NOT COMPARABLE.


Regardless of what you read HERE on the fire, BC AND SD have bearing on bullet comparisons.

As to 'energy' figures, that IS MATH. Mass AT Speed = WORK (energy)

The VALID comparison is to use as close to the same BC & SD at the velocity each cartridge is capable OF PRODUCING.


I know that 'energy' figures are poo poo'd around here, ever wonder WHY? The simple FACT is w/o energy, nothing gets done.

As to the 6.5s --- There ain't ONE 6.5 commercial cartridge that's in the same ballpark with the 300 WM.


Now please don't forget, I am not disparaging you nor the knowledge you posses for your age.

THERE , is still more.

Jerry

Not really sure how many years it takes to figure out that 7mm bullets offer more BC for less recoil.

The only point I've attempted to make is that 7mm bullets offer more, for less, as I said before.

To beat a 7mm 180 VLD, you need a Berger that weighs 230 grains. My point in comparing the 180 VLD and .308 180 NBT was that they weigh the same, but one is a very different beast. I apologize for not articulating what exactly I meant in that comparison.

I'm not sure where you are gathering that I believe BC and SD don't matter in bullets, because that's exactly what I'm talking about here. Exactly as Jordan Smith said, BC and lower recoil are means of putting a bullet precisely where it needs to go to kill critters. I try to take advantage of both.

Like I said, I have experience on game with both and enjoy both big fast 7mms and big fast 30s.

As for the 6.5 vs. 300 WM comparison, I'll let somebody else chime in on that one....
