Engraved bullets

Pulled these out of the brim today . They show the difference in rifling clearly .Marvin

I have many excellent examples of "engraving" on FMJ's I have recovered. And they are impressive. These (38/45) are in such perfect non-deformed condition, I will probably reload them!

I do not have any way of accessing my spent cast rounds but, if you do, that is an excellent method to see what/how your sizing and casting is actually doing!

I PC everything now and several on here have been fortunate to recover their own PC'd rounds and the coating is still on there! Says a lot for the coating technology.

No PC but these pictures are down sized to load here . I have a Cannon S5IS camera with super micro . It will do wall paper size photos . When I load the pictures in my computer at that size and magnify them not much escapes the eye . Just about like a good microscope . Helps when I am looking at a problematic mold as well . I started to size the 308 Corsair bullet again to .309 because of the lead that is getting pushed back . Did not have the occasional flyers today . I got lazy and was trying to skip the sizing process . Marvin

Heh.... I think PC he speaks of is powder coating. But either way cool pictures. I mine for gold, I mean lead and frequently find damn near perfect jacketed rounds with the grooves.

I have a couple of found pistol bullets in my collection. One is a .45 ACP bullet that washed out of a clay bank, the other is what looks to be a .44 Magnum bullet I recently found laying on a walkway at a apartment complex out in the country.
The .45 shows deep precise grooves, the .44 looks to have been fired from either an extremely worn or oversized bore, the rifling marks barely showing.
The .44 is a exposed lead hollow point, showing no deformation at all. I figure this was a round fired straight up and falling to the ground, probably in the turf above the walkway and rolling down.

Either bullet could be reloaded.
They say that in Afghanistan and Pakistan some tribesmen were known to mine the berms of old military shooting ranges and dig out good bullets which they filed and polished to remove obvious signs of rifling, then reloaded these.

Long ago I read a report on anomalous rifling engraving of recovered bullets.

In a murder case the weapon that fired the fatal shot was known and recovered at the scene, but test rounds showed very different engraving.
The weapon was a .22 RF and they found that the box of ammo that the fatal round came from had remaining ammo with a great deal of waxy lube on the bullets. The test ammo had relatively little lubrication.
They found that when the overly lubed bullets were used these skidded in the bore leaving much wider land impressions than had shown on the test bullets.

So you are saying lube the hell out of my boolits and make sure there are no additional assembled rounds??

If you mean in case you wanted to fool a forensic examiner, they are already on to the trick. You can learn a lot about ballistics and bullets from studying forensics text books.

Bullets skidding in the bore are likely less accurate so excessive lubrication should be avoided.

I have been shooting my 201 that I put a .250 TJ barrel on lately . They are .0005 over groove diameter and 10bhn . Cast out of a LBT mold . Went with his design to get a good BC and less drift than a wide MP. Bullet was designed for mostly target use but will work well on small varmints with proper shot placement . Pulled these out of the sand today . Bullet has been working well for me . Shot over a 1,000 of these this week alone . That made finding these easy . They are 62 grains going out at 860 fps. on low power at 21000 psi. Marvin

I shot these in my 45 caliber Corsair . Which has a .452 TJ liner for a barrel . They are .0015 over groove and 15 bhn . They are shot base forward for accuracy .Marvin
