510 whisper vs steel plate

[@AccuracySpeaks]

Awesome!! Looks like someone throwing a football! Lol!

[@ferna2294]

Is it basically a subsonic 50 bmg projectile? Or is there any difference?

[@ranb40]

It uses the same projectile as the 50 BMG, but since the cut down 338 Lapua brass case is much smaller I can use 27 grains of powder to shoot the bullet 1050 fps instead of using about 50 grains in the much larger 50 bmg case. The Encore carbine also only weighs about 9.5 pounds with the silencer attached.

[@ferna2294]

I get it. I really like the concept. I was going to ask about the case but you just answered me hahah.

[@nicholasplesko533]

What’s the maximum point blank range of 510 whisper?

[@bigredone1030]

what?

[@nicholasplesko533]

@@bigredone1030 max range before the bullet starts to dip from the point of aim.

[@bigredone1030]

@@nicholasplesko533 I know what it means, but I don't think you do. It depends on how far you zero it as the bullet it travelling upwards until it hits your zero distance. Theoretically, there is no such thing as point-blank range as gravity is always acting on two objects, in this case the bullet and the Earth. The speed in the fall is the same, whether you drop a bullet out of your hand or shoot it out at high speeds- it will always fall at about 9.8 meters/second ^2 with a little off to account for air resistance.

[@nicholasplesko533]

@@bigredone1030 Specifically, there is a point in which the bullet will have reached its highest point after leaving the barrel and the bullet will drop. For a 5.56 out of an m16 its about 260 yards. I want to know how far a 510 bullet will go before its trajectory stops looking like a line, and starts looking like a rainbow. How far does this thing shoot straight before gravity turns it into a softball pitch? When does it go from laser beam, to piss? That's all I'm asking.

[@bigredone1030]

Nicholas Plesko It depends on the zero. Everything drops at the same velocity regardless of mass. The reason the m16 drops that far is because that person zeroed for 100m. The angle of inclination is the key factor in a zero. That’s why extreme long range guys have a 20 MOA rail; because the slight angle is needed for the round to hit where it is zeroed. In summary: no round looks like a “line” when graphed. Gravity applies to every physical object on Earth, all the time.

[@chapter4travels]

I think it would be fun to cast your own bullets (and powder coat) to see how large a bullet you could keep stable in flight.

[@ranb40]

The largest I've used so far is a 950 grain cast bullet with a gas check. The mold is from Cast Bullet Engineering in Australia.

[@Jay_in_Japan]

With a fast enough twist rate, I suspect that you could stabilize a fairly large bullet

[@luzianwasescha6056]

What barrel length are you rocking?

[@ranb40]

20 inches. There is a muzzle brake machined into the muzzle. The silencer telescopes over the final six inches of the barrel.

[@Make_Boxing_Great_Again]

1050 fps is too fast, you are still in the transonic region, you can improve accuracy and sound levels by dropping the speed to 900fps.

[@ranb40]

The bullet is about 2 inches long and the barrel only has a 1-10 twist. When loaded slower I did not gain any accuracy or reduce noise. The CCI Std Vel 22lr in my Savage moves at 1060 fps, it is rather accurate. 1050 fps also works well in my 300 and 338 Whispers. I do not have a proper noise meter to see how reducing the powder charge will affect noise.

[@Make_Boxing_Great_Again]

@@ranb40 It also depends on temperature, on a hot day you can run them faster and still stay below the transonic range which usually starts at .8 mach.
