Can it be done? And would it still be accurate :confused:


I think it would be cheaper than buying HP Bullets. :D

It would be tough to do well.

If you had a Vertical Mill and a collumator or a good vise you could first flat spot the projectile end with an end mill and then drill it center.

If your an experienced Machinest you could probally do everyone the same and I see no reason why they wouldn't be equally accurate.

Now as to how accurate they would be as compared to the orginal FMJ projectile profile? You'd have to be an engineer to figure out he co-efficent of drag and all that stuff...:D

A lot of work for unknown results IMO. Also if your trying to dthis with a dremel or a hand drill and a bench vise do your self a favor forget about it.

DO NOT DO IT!

You will be left with a copper jacket open at both ends instead of a bullet.

The lead core can then be blown out , leaving the jacket stuck in the barrel.

The next shot will result in a ringed barrel, or worse!

All jacketed bullet must be closed either on the front or the rear.

FMJ bullets are closed in front, and open in the rear.

Soft points & hollow points are open in front, and closed in the rear.

^^^^what he said.

FMJ bullets are closed in front, and open in the rear.

Not all FMJs are open at the rear. Most are, but not all.

Accuracy will likely be awful - drilled off center, inconsistent amount of material removed, burrs, et. al.

Not all FMJs are open at the rear. Most are, but not all.You know that, and I know that.
But I was trying to make a point!
(Without writing an essay on bullet construction)

Plated FMJ bullets don't have an open end. (Lead-Free & Berry / Ranier)

Tracer bullets, Incendary bullets, and some other types of military bullets don't have an open end.

But except for plated FMJ bullets, they all did at some stage of the manufacturing process.

If it was made with the cup & core swaging method, it has, or had one open end unless closed with a copper or cumbustable sealing disk.

And it wouldn't expand much if any, either. The nose on a FMJ is the thickest part of the jacket and a reasonable size hole would not mushroom it. Didn't work for the British in the original Dum-Dum, won't work for you.

This too. Getting an HP to expand/fragment requires very specific bullet construction - way beyond just "drillin' a hole thar".

Thanks for the info yall. :)
