That's what I expected, but didn't want to assume it to be true. Thanks for relating your experience.

Re: Walking or light rifle... elk at 600 yards

The 338 win mag is a choice i made over 15 years and have had no regets
The 338 win mag at 500 yards has a 2000 flbs of energy with a 225 accubond
with 2708 fps on the barrel and 2005 fps at 500yards. the Rifle is a standard ruger
24" barrel wood stock iron sights and a scope.....Has put pronghorn, deer and elk
on the table.
As for all else 300 win or a 06 which will kill all needed animals in North America...

4point, When you quoted alot of the ballistics, you where refering to drift and drop, but compare ENERGY at the farther ranges, that is where the 338 gains, that is why I BOUGHT A 340 wm 20 yrs. ago

Re: Walking or light rifle... elk at 600 yards

Other than printing a drop chart I know nothing about ballistics programs. For the most part I am computer illiterate. SO what I say is from experience only.

You have been given a wealth of great advice. I have taken deer and elk to 650 yards with 6mm Remingtons (deer) to 338 Win Mags. My old favorite all time caliber is the 300 Win Mag with 180 grain partitions. Now that bullet has been replaced with the Accubond. For elk and above, there is a noticable difference in visual response when hitting a large animal with a 338 caliber bullet over the other smaller calibers. Do not misunderstand, to 300 Win Mag,300 RUM do the job every time without a hitch.

As previously stated, one cannot always find an ideal place to shoot from. SO scope eye is going to happen with 4" eye relief Leupold scopes and soft spongy recoil pads. Personally it takes only a moment to put on hearing protection. Which for me makes having a brake on my 6-8 pounds 338's a very pleasant experience.

Re: Walking or light rifle... elk at 600 yards

4th point,

I also used the JBM program to crunch the drift for the 200 gr accubond. I must point out that your figures are very different from mine. I have no idea what you used for zero, elevation, temp etc. All I can say is that you are WAY off.

I will get more specific so perhaps you can find your error in your figures.


I used .588 as the BC, 4000 ft elevation with CORRECTED pressure of 25.84"
temperature 50 degrees F, humidity 30%,0 mph 90 degree crosswind, scope height 1.5", Zero 200 yards.

600 yds drop is 55.7" and drift is 15.1"

------------------------

588 is Nosler's BC number. Bryan Litz has a lower number and recommends the G7 BC which is
.273

Crunching all the same inputs with corrected BC yields:
drop of 56.8" and drift of 16.4"

--------

I am curious as to your input data

Re: Walking or light rifle... elk at 600 yards

I would go 300WSM and start out trying the new 168 grain E-tip. It could easily be lauched at 3100 FPS and is still travelling at 2050+ FPS and carrys over 1550 ft/lbs KE at your max range of 600 yards. That assumes 1,000 ft elevation and most elk hunts are 5,000 ft or higher so your downrange numbers will probably be better.

The min impact velocity is 1800 fps so you would still be over 250 fps above that value and the bullet would surely penetrate with 95% weight retention.(Probably better than the 180s) It has a .503 BC which runs right with most of the 180 grain premium hunting bullets also.

Kimber Montana would fit the bill for a lightweight carrying rifle and the savage weather warrior are right in there also.

Re: Walking or light rifle... elk at 600 yards

Good points guys.

We've got elk at sea level (literally) to the highest mountains in the state, and everywhere in between. I would guess that most of my elk hunting was/is/will-be at 500 to 4000 ft. Probably in the 1000-3000 ft range 50% of the time.

In post #12 I didn't list the parameters used in JBM other than sea level and 59 degrees. I should have stated that I used the default settings to compare the 300 vs 338. One of the most important settings is the zero... 100 yards is default for JBM and what I have been using lately since I now dial drop and drift.

When I run numbers for one of my actual rifles or loads I am much more specific, but since I just wanted to compare the two cartridges for relative differences I just used the default settings. I was lazy, but the numbers are still valid to me since each was calculated for the exact same conditions. I just wanted to know the difference.
