Has anyone tried using the 400 grain High BC 416 Barrett bullets with the 416 Rigby?

If people are pushing the Rigby to 400 @ 2700 FPS it would seem that the Rigby/Barret combo would be a good 1,000 yard rig.

The 50 BMG is pushing high BC bullets @ 2700 so this would be interesting.

is this actual test data, or a projection based on the MV the 416 Wbee achieves with a conventional SP or Solid? The weight is not a problem, but the amount of bearing surface may affect achievable velocities. Got an actual BC to work with?

Knowledge not shared is knowledge lost...

I have seen a BC of .900 in print somewhere.
If you do a search on .416 Barret this forum, we have done some calculations with that number ...

Here is something for Boomer to put in his pipe and smoke (notice some SHark gills here, even a double SHark gill and a wasp waist):


These are only crude estimates from looking at 2 pulled bullets.
Gross case capacity of the fired .416 Barrett brass is about 232.7 grains of water based on only three cases measured.
COAL of loaded ammo is about 4.569".
Bullet OAL is about 2.078".

Nose length from the rounded meplat to the death-crimp spot at the first gill is about 1.290".
Measured unfired brass length was 3.265".
I have seen max brass OAL quoted as 3.266".
I have been seeing the bullet called a 395-grainer in print lately.
I only pulled two and got 391.3 and 391.1 grains on the weight, but they might have lost some brass to the vice grips scratches.

These are apparently now 395 grainers, not 400-grainers.

"395 Bullets!"

GSC makes a very sleek .416/420-grain SP.

This was my first encounter with a rebated boattail with a nipple.
Does the nipple on the bottom of the bullet offer a ballistic or a machine-work advantage?
A way to fine tune the finished bullet weight by polishing off the end of the nipple?
Or is it just supposed to be sexy?
Sumbuddy who know?

None of the above.

Lapua made some 50 BMG bullets with the same tail geometry.

In use they performed no better than and sometimes not as well as traditional designs.

Suppose it was intended to move the wave form further aft thereby reducing drag. I like the weigh and trim idea though!

Thanks for the info and pics...

So with the Advent of the 416 Barrett bullets is the 416 Rigby now a 1,000 yard rifle???

Boomer,
Let us know if you find a source for the proprietary brass Barrett bullets besides pulling them from the $6 per pop factory ammo. BTW, those .416 Barrett cartridges are loaded with about 195 grains of ball powder.

So, if you can get any 400-grainer up to 2700 fps in a .416 Rigby, you ought to be able to get the Barrett .416/395-grainer up to 2700 fps by selecting a proper throat for the chamber and single-shot loading them in your magazine rifle or Ruger No.1.

However, you will need a faster than standard TWIST for your .416 Rigby .

The .416 Barrett uses a 1:12" TWIST at 3250 fps from the 32"-long barrel.

You might want to try a 1:9.969" TWIST for equivalent RPS with the subject bullet leaving the muzzle at only 2700 fps.

I think 1:10" TWIST should be close enough.

Good to see Gerard is on the job keeping ahead of the industry, even pioneering the revival of a new-old caliber, .395.
