I've read the reports........out does all of the .300 mag..........tons of speed, tons of energy.........anybody have one?

Im in the market for a good rifle...its got to be ready to stop everything in NA....i know it will but anybody have any faults about it?

Don't forget...tons of RECOIL, tons of money, tons of powder, tons of heat, pitifuly short barrel life, and it won't kill any animal any deader than a .300 Win Mag, .300 WSM or .300 Wby. Mag at the same ranges. The .30-378 is beyond the realm of practical, IMO. It may have a place in 1000 yards competition, but as a practical hunting cartridge under realistic conditions, there are just too many drawbacks to outweight it's paper performance, and too many cartridges that will do exactly what it can do with far fewer drawbacks.

$78 dollars a box of 20. Is a bit much to me. I have a good friend that shoots a 30-378. If we go to the range he crys at every shot telling me what it cost to shoot :} It is a better down range gun than my 300 win.[I meen over 500 yards] but my 300 weatherby sticks right up there with it.

He allso has a sholder pad put on his shirt. mmmmmmmmm Maby this meens it kicks?


One thig he shure looks good carrying that great big thing all 9 miles. Boy it is decked out HUGE scope MONSTER tripod he allso has a ton of weight in ammo on the stock. He is about 5' 7" and 200 pounds.

How much does this baby kick? Are we talking more than a .338win mag?.......more than a .375H&H?.......i reload so i can save on shells.....and is it really that much heavier than other calibers its size?.......i look at the catalogs and the make and model of the gun depends on the size......the sako trg is 8lbs.......thats nothing!!.....plus the more weight the less recoil........im not superman but im know i can handle 8lbs and some recoil........everyone knows recoil is only felt during practice!!!!!

Exactly.

Practice is also where you learn to flinch

To answer your question about comparing the recoil to other rounds...

Assuming that all three rifles weight the same at 9.25lbs, here's how they stack up with what I believe are typical loads at roughly the average published velocity for that bullet. The data was taken from the Hodgdon load data on their website.

The junior member of the trio, the .338 Win Mag, shooting a 210gr. bullet at 2850fps with 67 grains of powder will produce 29 ft-lbs of free recoil energy at a velocity of 14fps.

The .375 H&H, with a 300 grain bullet propelled by 78 grains of powder at 2600fps will slap you with 44 ft-lbs at 17fps.

And the bruiser of the bunch, the .30-378 Wby. Mag, shooting a 180gr pill over a whopping 110 grains of powder at 3400fps will sock it to you with a bone jarring, tooth cracking, retina separating 54 ft-lbs of energy at 19fps, and that's with the lightest bullet the data provided. With the long 220 grain Nosler Partition the recoil goes up a touch to 56 ft-lbs and 19fps.

So the .30-378 has 18% more free recoil energy than the .375 H&H, and 46% more recoil than the .338 Win Mag in the same weight rifle.

If you compare the trajectory of the 30-378 to a milder and more practical 300 magnum like the 300 WSM, you'll see that there isn't much practical difference at hunting ranges, which I'll say maxes for all but the most talented marksmen at 400 yards.

If the two cartridges fire the same 180 grain bullet (180gr. Hornady SST with a BC of 0.480) at velocities typical of the cartridge, 3400fps for the 30-378 and 2950 for the 300WSM, the trajectories are as follows (250 yard zero):

30-378: 100: +1.76", 200: +1.56", 300: -2.61", 400: -11.33"

.300WSM: 100: +2.66", 200: +2.18", 300: -3.62", 400: -15.58"

So the difference in trajectory is a mere 1" or less out to 300 yards, and only a touch over 4" lower at 400 yards.

The 300WSM, with a lighter 7.75lb rifle and 65 grains of powder will hit you with a still stiff 30 ft-lbs at 15fps, but with a rifle you wouldn't mind humping around all day.

All above have summed it up well. For the price you pay. (Not just Money) It does not outperform the other 300 Mags by enough to matter. For me that is. All in all the 300 Win Mag would be my choice. I would be just as happy with the 300 WSM

duramaxlt

the standard 300 wby. will kill anything in NA it's all you need.

The 300ultramag is very close in performance to the 30-378 but with much cheaper brass and factory loads and less recoil.
