Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

I weighed the bullets as they came out of another box I opened, 25 bullets,
some with oil filling the hollow point to within a few millimeters of the meplat
some with no visible oil at all.
Yes, highly variable oiling of bullet hollowpoints.
24 of the 25 were in the range of 402.9 grains to 404.0 grains, with oil.
1 bullet was an outlier: 400.2 grains

There was no discernible difference in the one aberrant bullet that I could measure.
There was no oil in the hollow point.
I would have to guess it was some sort of metallurgical flaw causing the one light bullet.
I sprayed the one wild bullet with Gun Blaster degreaser/cleaner.
Weight was unchanged, stayed 400.2 grains.

By grasping one of the oil-filled bullets by its base and slinging or flicking the hollowpoint at my thigh as I sit,
it leaves a fine-line trail of oil several cm long across the fabric on my thigh.
Black sweatpants show the slung oil as a dark line on the fabric
Re-weighing before and after flicking bullets shows that they can come with up to 0.6 grains of oil in the hollow point.

Above weights on same cheap digital/electronic scale by me.
I am going to have to break out my magnetic damping mechanical scale and weigh another box of 25.
Watching for anymore outliers, of course.

The first sample of 10 bullets weighed, after being flicked and wiped of oil, averaged 403.1 grains +/- 0.3 grains,
with no outliers in that sample !
