338 win mag, 300 win mag, or 300 weatherby mag?

[banjo318]

If one's objective is to shoot bullets accurately and shot placement is paramount, then consider the cartridge that has the least recoil. Doesn't matter if a brake lessens it after the bullet leaves the muzzle; it still moves a lot while the bullet's going down the barrel.

Belted cases are not all that great for best accuracy when reloaded. Rimless bottleneck ones are much easier to reload to be a tack driver.

I consider the .300 RUM the ultimate compromise to have the best suite of accuracy, shootability and hunting performance at the longer ranges. It's worth opening up the bolt face.

I find the whole rimmed case stuff to be complete and utter ********. My 7mm rem mag shoots .3 inch groups all day long. I just gotta do my job.

300 grain matchkings and 220 partitions. Of course this is not with the same powder, but its the best velocity i can get out of it.

The 220 partition has the ballistic qualities of a brick, run your numbers with a real long range killing bullet like the 215 Berger, it'll change the numbers! You'd be better of running the 250 Berger Elite hunter or 225 Interbond in the 338 but still at a grand the impact velocity is a little lower than I like, I really like the 338 Win to about 800 yards on the far end, my next one will be a WSM version for a packing elk rifle.
The 338 RUM will make the 338 Win look stupid when it comes to elk at a grand, you don't have to mod your bolt face at all, I have two Rem 700's and two Savages around here in RUM or WSM and all but one started as a 7mag with no mods, the one thing that can be an issue with the RUM is mag length which on the Rem is easily solved but the Savage your kinda stuck but I don't mind single sledding if it means accuracy and performance at long range.

I don't think so.

The difference in what they do with the same bullet's not worth having to reform cases before you can shoot them in my opinion. That subtracts from "shootability" which includes getting components and loading them.

I'd like to see the muzzle velocity difference between both cartridges with the same barrel length, peak pressure, bore and groove dimensions for heavy 30 caliber hunting bullets. This would be a realistic comparison. Even if the .30-.375 shot 'em 50 to 100 fps faster, that' enough to negatively effect "shootability." More muzzle velocity is countered by more recoil making the faster ones harder to shoot accurately.

The 30/375 S.I. will run a 215 grain bullet to 3050 from a 28" barrel, same ballisticly as the 300 win mag but without the belt, a longer neck, and a better case design IMO. An OAL with 215 berger is 3.705. You burn about 15 grains less powder than the 300 rum. The reason we are rebarreling our 300 RUM to 30/375 S.I. is shootablity, a lot less recoil, muzzle blast, better case design.

I said at the muzzle you dip.

 

[banjo318]

Im actually probably gonna go with the 340 weatherby magnum.

 

[bigngreen]

Just to put this out there, the 339 win mag has a 200 ft pound of energy advantage over the 300 weatherby.

Well im going to rebarrel my 7mm remington magnum soon. So i need to decide on a longish (to 1000 yards) hunting rifle. I need to make a point that the 338 win mag is flatter shooting than the 7mm remington magnum and provides way more punch. Anyways, I have a 300 win mag and its wonderful for that, but the 300 weatherby is better. The 7 stw might be an option but i dont think ill choose that. This rifle will be used at 400 yards for the closests shots. It must be able to take down elk at 1000 yards. (must still have 1500 ft lbs of energy at 1000.)

I said at the muzzle you dip.

Actually you don't have a clue what you said, never have you said muzzle energy which who cares about any way since it means nearly nothing to long range shooting.

 

[banjo318]

Oh, i said that to someone else somewhere here. Thats what i meant. So calm down, thats all i was saying.

any round discussed here recoils. The differnce in how muich as to how it effects the bullet in recoil is minute. Ive seen many sub one inch groups shot with 458mags and 460 wbys. Your arguement about belted cases holds even less water. The good old 300 win mag won lots of long range competitions back in the day and were not talking group shooting here were taliking hunting. Ive got a 300 win mag a 300 wby and a 300 ultra and out of the three the ultra is hands down the most finiky to load for. Due no doubt to its overbore powder capacity. There is absolutely no differnce in a belted case or a non belted case for 99 percent of handloaders as 99 percent of the headspace on the shoulder just like a non belted case. Personaly ive found the 7stw with its belt alot easier round to work with then the 7 or 300 ultramags

Finally, someone that agrees with me....

 

[D.Camilleri]

I just ran the numbers on a hypothetical 338 win mag with a 300 grain Berger with a B.C. of .818, a muzzle velocity of 2450, this bullet would stay above 1000 lb ft of energy out to 1600 yards. So, high B.C trumps high velocity and lower B.C.

There are many that will disagree; those that shot those belted cases winning matches and setting records. Unless you can shoot sub 1.5 MOA at worse with a shoulder fired rifle (no artificial support in any way) at 1000 yards with any 30 caliber magnum for at least 25 shots as well as hold a high power long range high master classification card, you don't know what you're speculating about.

I've been there. Done that. several times. Have you?

my long range heavy hitter is a Rem 700, 338 RUM. 225 Accubond, 3200 fps but 1500 ft lb at 900 yds thats 1275 @ 1000 yds. It has spectacular performance on game. For comfort it has a cfl brake. and limbsaver recoil pad, and is comfortable to shoot. Have never got a 1/4" 3 shot group but often get 5/16", also has 4.5-14x leupold LR, with custom premier reticle lines and hold over dots to 1100 yds. I'm sure there are better but i love this one.

 

[Larry Holland]

I have shot all three Plus another .338(LUPA) & of the three previously mentioned I would go with the .338 Winchester Mag. & a 250 grain bullet. When in Alaska I talked with 10 guides & 5 had .338 Win. Mag. & 5 with .375 H&H!

 

[wileycooley]

I agree with your energy threshold. P.O. Ackley recommended Elk minimum 1500 ft lb,adequate 2000 ft lb, best 2500 ft lb at the distance the game was taken. Im interested in knowing how you will get this much energy to 1000 yds. with a suitable hunting bullet, with the cartridges you have selected.
