Mark V 416 Weatherby Magnum Accubrake - Using 120grs RL-22 I have no max signs and base of brass expansion after fired measures less than .0004 and there are no shinny marks on bottom of the brass and no flattened primers. My average velocity is 2930fps, shooting under an .625" at 100yds. The 350gr TSX is outstanding. My OAL was 3.750" I have put a Leupold VX III 2.5-8x36mm on the rifle. Here are my load ballistics.

Muzzle 2930fps - eng. 6671 pounds
2750fps +3 1/2" 100yds - eng. 5876 pounds
2577fps +4.04" 200yds - eng. 5161 pounds
2410fps - .73" 300yds - eng. 4516 pounds
2250fps -11.5" 400yds - eng. 3935 pounds
2096fps -29.3" 500yds - eng. 3414 pounds
1948fps -54.6" 600yds - eng. 2950 pounds

I can hit out to about 370 then hold cross hair on top of shoulder and hit out to 430 to 450 on deer and elk size game and a little further on moose. Will work real well on big bear. Now this does not mean I will get the chance to make a long shot, nor take one unless I am sure and it is not dangerous game. I will practice at long range to get use to it. But this will be devastating up close or far off. What ever it hits it will be dead. This 416WBY completes my trio of Weatherbys. I have a 257WBY, a 300WBY and now the 416WBY. The 257WBY I named "Nancy Jean" (my wife), because the 257WBY does not hit me back when I pull the trigger and it has fine lines and shoots straight. I named the 300WBY "Thors Hammer" because of the 180gr TSX that moves out at 3287fps and hits with authority. I named the 416WBY "Odin", Odin was the father of Thor in viking myth and Odin was brave and would face the enemy up close and not run, delivering a deadly blow. I am really excited about this load and its potential. later

I may be biased, but your lacking a 340 weatherby or a 338-378. The 416 is a cool gun with the muzzle brake on, can be a bit brutal without... Don't forget to acutally range check the drops, they can vary by 6-7 inches at 500 yds from published. Have fun!!

Yes, I will check them as you said when I practice because I have experience exactly what you said in the past.

john may be right about the 340 but I would do the 378 now that you know that you can handle the recoil just one way to go the 378 has lots of 375 bullets out there to pick from more than the 338 john what do you know of or think about the 358 norma I ordered one it is not here yet

I scoped it with a VX III 2.5-8x36mm with Wide Duplex. The Wide Duplex is really nice, it allows me more of a picture for acquiring the target quickly. Might need that if you know what I mean.

I will go out again the end of this coming week to tweak my sight-in for my load and shoot through the chrno again so I will have more data than a three shot group to average my "fps" and "deviation of velocity spread." This will help me calculate what to possibly expect when I start to practice on long shots. As I said earlier, the accubrake makes the 416 feel like a 220gr load in a 300WBY with no brake, but that is not bad considering the power and the mass of bullet I am sending down range. What amazed me is that the 416WBY has as much energy at 600 as most 06 loads at muzzle. Wow!! what a cartridge and rifle. This rifle makes you feel like you can face anything any where. It should be impressive when it hits the game. Yes! This was the right cartridge to complete my trio of Weatherby's.

Hey 5BB, not bad for a big cartridge to not kick any more than the 300WBY with a 220gr bullet and have a Taylor Knock-out value of 146.5

Wow nice loads, I just received my 378 and starting loads 117gr RE22 260gr accubond chrony at 3427fps, energy 6800. WOW these muzzle brakes are amazing. Like shootin a 338 winny.

Amen on the muzzle brakes!!!!

I believe Oden and Thor currently reside in Valhalla. Perhaps I can get a good deal on Thor's hammer since he's not using it any longer - it'll save me from buying a Weatherby. While I am there I'll also check out a couple hot valkuries.

Now that is funny, I like that

I just reach for my trio when it comes to deer, elk or anything bigger
