big bore choice?

The 416 Rem. Mag. is more efficient than the 375 RUM. It can drive a 350gr bullet at 2700 fps with less powder than the 375 RUM uses to get the same speed with a 300gr bullet. And with 2" less barrel length. Plus it has about 25% more cross-sectional area = more shock.

I was getting 2850 fps when I loaded 350s in my 24" .416 Rigby. As for the .416 Remington being more efficient than the .375 Ultra, you're not comparing apples to apples; a .416 bullet that has the same SD as the 350 gr .375 would weigh 430 grs. How fast could a .416 Remington push a 430 gr bullet, even if you could find one? Probably about 2400 fps, similar to the velocity I get with a 380 Rhino in a 22" .375 Ultra, and about 100 fps behind what I get from the .375/350 gr Woodleigh.

That's for sure, the 416's are in a different league altogether. ;)

That's true, but not the way you think. Load a big case .416 with the heaviest bullet that allows it to make 3000 fps, then do likewise with a .375 Ultra or a .378 Weatherby. At 500 yards the .375 will have less drop, and puts more energy on target than its pudgy brother. I do like the .416 bore rifles though; when coupled with big cases like the Ultra, Rigby, and Weatherby, the .416s are the largest bore size that, IMHO, can be considered true general purpose cartridges.
 
Have owned several .458s but never shot anything bigger than prairie dogs. Have taken one Elk with the .416 Rem. 300X at 2900 and one grizzly, 350x at 2600. The .416 worked very well in both cases.

Not so.

Check out these numbers. The 416 Wby has less impact drop and 600+ ft-lbs more energy at 500 yards than the 375 RUM. Plus about 25% more cross-sectional bullet area than the 375 = more shock.

The 416 rules over the anemic 375! :cheers:


375 RUM & 260gr AB @ 3026 fps (Nosler data) VS. 416 Wby & 350 TTSX @ 2967 fps (Barnes data):

The .416 Weatherby is clearly a star, as is the Rigby, but I thought you were claiming the .416 Remington was superior to the .375 Ultra. Too bad Remington hadn't thought of using the .404 case when they decided to jump on the .416 bandwagon, a .416 Ultra would have been some cartridge.
 
Just for giggles I ran the 350 gr Cutting Edge Lazer in JBM to see what the prediction was using the same muzzle velocity I got for the 350 gr Woodleigh from my 22" Ultra. Its impressive, at 500 yards the velocity is still 2031 fps, and the energy is 3206. Not bad for a hunting bullet starting at 2500, but it needs a 1:10 twist.

Edited to add . . .
Cutting Edge makes a .416 Match/Tactical/Hunting bullet that weighs 472 grs. If you could handle the cost and recoil of loading in a Weatherby cartridge, it would be a performer.

CEB's are the bullets to use on long range targets. Amazing ballistic coefficient values.

Standard twist limitations for production rifles: 416's - 1:14 / 375's - 1:12

Any love for the 404 Jeffrey here?[/QUOTE

Yea its KOOL but the 416 Chatfield Taylor outperforms it ! :p jmo RJ

Yes it does! And, it's much easier to find brass.

Every 416 CT case I ever used was formed from picked-up 300 and 338 Win Mag brass at the range. Bevan King installed one of his barrels on a Turkish Mauser, 400 gr Barnes Originals loafed out of the barrel at 2300 fps, and the brass lasted forever. :)
