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

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.

In no particular order!!

There is NOT as much L R hunting ACTUALLY done Compared to how many TALK it.. I had a thread on the L R forum on THAT subject.

There were only a FEW. Less than 10, who said they killed game 500 yds and out.

OTOH the subject of B C has merit for more than L R comparisons.
Yes B C is more important at L R because it relates the aerodynamics of bullets.

300 yds. Is not considered L R yet B C is relative for 300 yd. shooting/hunting.

To state the OBVIOUS the B C numbers relate the efficiency of different bullets in flight. Many or most Xs experienced shooters can tell the relative efficiency by simply looking (for short range, 300 yds. or less)

I found B C and S D particularly helpful as an inexperienced handloader. Yes I know that S D changes or dissipates upon impact BUT....

S D relates the penetrating quality of bullets of the SAME construction.

eg. Using the same bullet manufacturer with the same construction B C & S D indicates flight & penetration between lighter & heavier bullets.

IMO - IMO more people use the numbers of Bergers or Scenars to prove their points THAN actually USE those bullets for hunting.

I am OLD SCHOOL, if ya can't tell <G>, and for 400 yds. And less these high numbers from Berger aren't nearly as important.

If I never read or hear about Bergers again, I would not miss it.

All fun with numbers aside the .264 is dead and the 300 win mag has more stomp than the 7mm mag.

LOL now that's damn near comical tell it to those that are using them to hunt with.
