50BMG VS 416 barrett

[dirteemax]

dirteemax,

jimmym40a2 has some of those calibers and access to the others. If you want someone with real world experience, he is your best resource on here.

However, that analysis is with custom projectiles that may or may not be available up here. The results may be different depending on the BCs of the bullets you can get.

If you really want a 416, you're best to see if you can actually get high-BC bullets in .416 here and then design a chamber reamer around one of those and also look into a reamer for making the dies. If you can't find anything, there is always the swage-your-own route...

All the cnc machined bullets are available on barretts website and wolverine supplies can get the bullets and brass rite from barrett. I have some of the barrett 416 brass sitting here rite now. The hornaday bullets can be ordered by any hornaday dealer in Canada.

So i think the good CNC machined bullets that he was using in his comparison are probably available up here as it is not illegal to export 416 from the states like it is with 50bmg

RCBS makes reloading dies so does Lee and it sounds like the guy at M2 precision may start making some "competition" reloading dies for the 416 as well. So getting the reloading supplies seems like it's going to be much easier and cheaper then getting 50bmg stuff.

Though I think the 50cal is still king of the hill so to speak. I'm just interested in trying something different that's all.

I would get the 416 over the 50 if components were easy to get simply because a lot of ranges ban 50 BMG by name or calibers larger than 460 and are completely ignorant of the similarities.

The most accurate report of a 416 I have heard of is Dale Polling who shot a 10 shot group at 3000 yards in 24 inches. He is the only one I know that has ever gotten this type of accuracy from a 416. He was shooting a EDM arms m96 with a custom barrel. I'm not sure of his bullet selection. There are some new cartridges in the works that will be supersonic to 4000+ yards.

First Caliber is the 375/408 using the 350gr copper/nickel projectiles.
Ballistic Coefficient: 1.120 G1 Bullet Weight: 350.00 gr
Caliber: 0.375 in

Second Caliber is the 408 Cheytac using the 419gr copper/nickel projectiles Ballistic Coefficient: 0.964 G1 Bullet Weight: 419.00 gr
Caliber: 0.408 in

Third caliber is the 416 Barrett using the 400gr solid projectiles
Ballistic Coefficient: 0.985 G1 Bullet Weight: 400.00 gr
Caliber: 0.416 in

Jimmy I am not familiar with those bullets but a quick look at the figures has me concerned that these might not be apples-to-apples BCs (their relation to each other is not consistent, unless the bullets are of very substantially different shapes and designs).

Not only is it difficult to accurately measure BCs (most manufacturers do not have this capability), there is also a tremendous marketing temptation to push the limits of truthfulness. Which makes comparing manufacturer-X's b.c. to manufacturer-Y's b.c. a nearly worthless exercise.

FYI for doing calcs that involve the bullet speed falling below 1500 or 1600fps, there are a couple of ways that will give better predictions:
1 - use a G7 b.c., if one is available
2 - "convert" the G1 b.c. to a G7 equivalent and run the calculation with the G7 b.c. and drag model.

Definitely; figure out what bullets you can use, and analyze on that basis. And since no matter what you do a rifle of this sort is going to be big bucks, why not turn that into a virtue and custom design it to be exactly what you "need"/want it to be.

the bullets on the 375 and 408 are lost river solids. it is the actual BC. proven. that is why the 375 is currently king of the hill, you will se some new 375s that will be even better in the next year or so.

I was under the impression that barrett rifles in general are prohibited in Canada.

 

[dirteemax]

Any one have a rifle chambered in .416 barrett??????
id love to hear some actual real life exuberance????

We are the Barnard dealer in Canada. You don't need to import from the USA to have the best in the world! Barnard makes actions for all these calibres.
