.308 projectile dimensions

[enduroed]

Hello all, brand new member here. I own a machine shop in Deland, Florida and have a friend who makes AR-15 lowers that wants to sell solid .308 and .50 caliber projectiles. I, being a machinist need a print, something with dimensions. Does anyone have such info?

Also, what would be a fair price for .308 and .50 caliber projectiles?

And last question, brass or copper?

Any info would be appreciated. We are slow right now and need some work to keep our spindles turning.

Thanks for the help.

Tks, Ed

Re: .308 projectile dimensions

no blue prints here. brass is the best material. i think you will have a hard time making them cheap enough to sell and make a profit

This might help:

The alloy used in machined metal bulltes is mostly brass with some guilding added to soften the metal for easier engravement in the bore. Many machine solids also have recesses machined into the shank so that 3 (or 4) pressure rings seal the bullet, cause it to spin, and avoid serious metal-to-metal wear problems as the bullet interacts with the bore.

MitchAlsup,

That is perfect. Mtrl cost is from 7.66 to 10.12 cents per projectile, about a 22 second cycle time. We have a used dual spindle Mori Seiki that is just sitting collecting dust, the parts will come off complete. figure to sell them for about 40 cents a piece. Is this a price that people like you would sell them?

Thanks mucho for the link.

Tks, Ed

You might lurk over on the 1000 yards and beyond forum, as there are a few custom bullet makers turning their own solids for the 2000 yard and beyond crowd. Seems the solids hold their shape better over the longer distance, where even a slight alteration of the lead core can spell disaster in that 2500 yard range.

Also, from what I understand, you need specially made barrels to shoot these solids, there is no lead core to compress, so barrels need to account for this lack of 'shrinkage'.

I'd learn what I could learn about making high BC bullets for .50 cal, .408 cal, .416 cal and .375 cal. It's not something that you wake up one day and stumble out into the toolshed and start banging them out. These guys know what they're doing and they test the stuff out quite religiously.

Forget the .308s, solids aren't really neeeded in this caliber unless you're doing copper and selling to hunters out in California, to save the vultures....er, I mean...the condors.

At $0.40 a piece I don't think you will see too many of us jumping to buy solid .308 bullets unless they showed an incredible accuracy increase.

Might try picking up a box of these to get an idea of dimensions. Bryan Litz's pages on ballistics would be a good place to read up as well.

Good luck,

Re: .308 projectile dimensions

You might tell him to check with the ATF. Yes an FFL is required to make & sell projectiles. Type 06 If he has any inkling to sell outside the contintntal US he needs to see the State Department as well.

Go to www.pmddtc.state.gov and on the Home Page click on the link to Registration. There you will find the application form and complete instructions for a complete submittal package.

If this is a renewal of registration, please note that renewal is exactly the same as registering for the first time. You must submit a complete package.

Re: .308 projectile dimensions

I did call the ATF and spoke with what sounded like a knowledgable woman. I told her exactly what I was doing and she said no kind of license was required. Per Victor N TN answer I will research it a little more than a phone call to an ATF office. Guys, thanks for the help and the input. We will work on some .308 then some .50 cal. As we make and test we will gladly take recommendations and let everyone know how our testing goes.

A big deal is I live in Central Florida. I need to find a range that can approximate the the Marines 200, 300, and 500 meter distances. This is the only shooting of long range I am familiar with.

Thanks again.

Tks, Ed

It seems the government offices just say what ever they want to.
