View Full Version : 308 win @1000 yads vs 357 mag @ muzzle

January 25, 2010, 07:00 AM
i was watching a sniper show on the military channel.The sniper trainer said that a 308 has more muzzle [email protected] 1000yds than a 357 magnum at the muzzle
.sounds like more liberal math to me ....Maybe he was thinking of a 32 acp and had a brain fart:D

No, he was right.

M118LR (which I think is what they were shooting on that show) has 547 ft-lbs @ 1000 yards.


Speer Gold Dot hunting 170gr bullet has 526 at the muzzle.


Federal 158gr JHP is 539. http://www.federalpremium.com/products/details/handgun.aspx?id=106

Of course you can get hotter 357 (Buffalo Bore is 750+), but he wasn't making it up.

this sniper shot 32 haji's in 3 days .I would rather have a m70 still though

Glad I know that info now.

+1 on the 30-378. I have one with 30"bbl. I use the 240gr in it. I tried to thread the needle at a 1000yds through a crono, but all I got was a destroyed chrono. I was hopeing that I could actually get a reading instead of trying to calculate. Good thing it was just an enexpensive chrono.

sc926porsche, if you use Sierra Bullets' software set up for the atmospheric conditions you shot in, and you've got chronographed muzzle velocities, it will calculate what the velocity is at 1000 yards. And it'll be within 10fps of being correct.

Or, use two 3 foot square 1/th inch thick aluminum foil coated foam boards with each one connected to your chronograph screen inputs. The bullet making a short between the front and back foil will trigger the start and stop timing pulses. Watched some folks chronograph a .308 Win this way; one chrono was at the muzzle the other was 999 yards downrange in front of the target.

What was the name of this show? I can't beleive I missed it.

I saw the show, I saw the comment, and when I saw comment, I just brushed if off as some worthless informantion.

My 357 load at the muzzle does produce at the muzzle then my 308 1000 yard load, not much but a little.

My answer is SO WHAT, I dont ever remmember shooting my 357s or any other gun at anything AT THE MUZZLE. I do shoot a heck of a lot of 308 at 1000 yards though.

More usefull info is the State of Wyoming required that for a pistol/revolver to be used for big game hunting, it needs to develope 500 ft lbs of energy at 100 yards. Normal 357s dont do that.

Be careful what you see on the History Channel or the Military Channel. Years ago I remember the History channel said Franklin Rossevelt was on Mount Rushmore. I've seen some dude on the Military Channel say that the 7.62 X 39 was more powerful then the 7.62 X 51.

I dont loose any sleep worrying about what either say. Like the 357 at the muzzle vs. the 308 at 1000 yards. Who Cares. I dont shoot 1000 yard targets at the muzzle of a pistol, nor do I stick a 308 cal rifle in my pocket for a Concealed Carry piece.
