Home Forums Hunting & Shooting Elk Hunting 7mm mag on elk vs. heavier calibers

So does that make the 7mm better? all I said is cant tell any difference. Some like the 7 some like the 300. Get over it man!

Just for Bob from JJ Hack.



Howdy Bob..I could try and compare others experiences killing animals on this forum, to what Jim H(JJ) has done but that would be fruitless,wouldn't it?

I hope your not grumpy too, over the 7MM..

Jayco

We all go with what we've learned from our experiences is what I say. Take your pic and rock on with it, what one will do the other will do. I just hope that we're all out there on the hill having fun and getting it done.

Dober

couldnt agree more Dober!!!

Some people seem to get their panties all bunched up over stupid chit!!!

Except shoot 200/220 and larger grain bullets.I said that in fun and I also said earlier pretty much what you just said,and I agree.To many take this internet stuff, way to serious.Hell,I have seen more Elk shot with the .270 Winchester than any other round, but that's just me and where I have been and the crowd I hung around with.

Jayco

I'm not sure I've ever shot a 220 except in an 06 about 40 yrs ago, sure thought those Minnesota deer were tough buggers back then..grin

But, I've total confidence that a 175 out of a big 7 will penetrate every bit as much as a 200 out of a big 30. No doubt at all to me.

Can't say about the 220 thingy, if I've gonna use something like a 220 then I'd be all over my 375 H&H.

And I'm like you, seen more elk shot and gasp they even croak via a lowly 270 and mostly with 130 Sierra BT's, 150 Horns and 150 Nozlers.

Dober

This is such a laughable debate

Can you guys really tell the difference between a 300 win mag and 7mm mag both shooting 180 grain bullets?

I have owned both but not at the same time. I have never shot a 180 out of a 7mm mag.

My point being I guess is they are the same cartridge loaded with the same weight bullet. How can one kick less unless its loaded to a lower pressure?

Dink

Thats the point i was trying to make!!!!!!

There is some algebraic relationship to the area of the base of the bullet and it's recoil...

Never seen the great advantage of a 7 over a 30. If I really want to reach out and hammer something a 300 Rum with a 240 SMK is head and shoulders above a 7 . A 240 gran SMK at close to 3K packs a lot of momentum once it arrives, not to mention the .711 BC

I found it...it was discovered by Jethro Bodeen of the Beverly Hillbillies.

"Pi aren't square, everybody knows Pi are round, cornbread are square"

In the spirit of fun,Alaska F&G ran some penetration test years ago and the 30-05 220 grain RNSP out penetrated all of them except the 458 Win Mag and a 510 grain bullet.

The 7MM was just shy of the '06 and 180's with the 175 in the big 7 but when it came to heavier weight,the 220 grain out of the 30-06 ate 'em all but the 458 Win Mag.

Kinda blurry..

Damn now thats funny........

Get over "what"? You seem to be the one all in a huff......I responded to Dober.I wasn't talking to you anyway.If you don't like what I say,put me on ignore.Don't bother me.

Bob, didnt mean to hurt your feelings

If I was to venture a guess Bob's BT/DT with hunting and wildcat cartridges long before most of us.He's forgot more than most will ever know.

Let's make it real simple.....

A 175 gr 7mm NPT has a BC of .519.

A 200 gr 30 cal NPT has a BC of 481.

let's use a 7mm Mashburn and a 300 Weatherby to push both bullets at 3050.

Let's put them both in 8 pound rifles.

It takes 87 gr of H1000 to move the 200 gr bullet at that velocity in the Weatherby.

It takes 73 gr of H1000 to move the 175 gr 7mm bullet to the same velocity in the Mashburn.

In drop to 600 yards, they are about equal;the 7mm bullet wins by an inch.

In energy the 200 gr 30 wins by 500 ft pounds at the muzzle(not that it matters because energy proves nothing).By the time we get to 600 yards, the 7mm will close the gap.

The 30 cal wins for bullet weight and frontal area.

Both will tear a large enough hole in an elk's lungs to kill him and break shoulders etc.

The two bullets will penetrate about the same.If you don't beleive me,ask Dober, or Bob Hagel,or anyone who has used equivilent 7mm and 30 cal bullets on elk.I have only used the 200 gr 30 cal on elk,and the 160 7mm. They all exited from shoulder hits.


The powder charge gets added to the bullet weight/velocity/rifle weight equation in figuring recoil.Anyone who has fired these two loads,at the same velocities,in 8 pound rifles,will notice the recoil difference.If they don't ,they are not telling the truth.Generations of riflemen from JOC to Page to Hagel to Boddington will say the same thing.

The 300 Weatherby will recoil more.

The 7mm will recoil less.

To make recoil equal, you must increase the rifle weight of the 300.How much? I dunno but 9-9.5 pounds sounds right.If you want a 9 pound rifle at 9-10,000 feet,be my guest.

Which is a better elk cartridge? The one in the hands of the guy who can shoot it best(remember the recoil)

This is why Les Bowman invented the 7mmRem Mag.Guiding hundreds of elk hunters, he noticed he had more wounded elk with the 300 Weatherby than the 270 and 30/06 because most of the guys with the 300's could not shoot them well because they kicked too much.....

.....I know that does not apply to anyone posting here because they can shoot the 300's as well as they can shoot stuff that recoils less......

.No elk will walk away from a solid chest hit with either.If he does,he was not chest hit.If he is hit in the guts with either,you have a rodeo.
