Stump shooting? You never know!!

	Just weigh the bullet, if it?s 230 grains it?s a 45. Most revolver rounds, especially those used for hunting will be flat nosed SWC or WC, or HP, Pistol rounds can be be anything again, but generally round nose for ease of loading, or HP for stopping power. the 45 HP would be 185 grains, but this is a round nose FMJ.

WRONG!

The weight does not make it a 45: 180  to 220 grains could be any 30 caliber bullet, also.

I have had 44-40 rounds with 400 grains, yet they were 44 caliber. (44 cal X 40 grains of powder)

Weight means little, only relative penetration ability. A 12 gauge shotgun slug is about 450 grains but caliber is not relative.

Measure the things, in millimeters (more accurate,) and convert to inches.

	True, but it is an indication, along with dia. But seeing as they?ve been fired and have penetrated wood (As opposed to entering a water tank in a ballistic laboratory), they will have deformed to some extent, even if only minimal. So measurement (dia. plus length), and weight in grains, is about your most accurate way of determining which type of weapon it was fired from. You could of course look with a microscope on the front side of the bullet in the hope of seeing on one side loading stripes, which would then confirm it came from a pistol, but there?s only a slim chance of finding those.

Yebutt! What about the loading in  an M1, what kind of marks will it leave and suppose they are pistol rounds, you are assuming autoloading, however a revolver would not have those marks.

Yes, diameter and weight, together, as long as you use Troy weight.... the regular pound (Avoirdupois,) has 7000 grains and 437.5 to the ounce, whereas Troy weight has 480 gains per oz.

Its like when Canada converted to metric, an airliner filled its fuel tanks in kilograms, they thought, but it  was actually in pounds because of the confusion in change over, so they only had half enough fuel. They had to make an emergency landing in the middle of nowhere, fortunately at an emergency airstrip. So never confuse ounces.

	Stumps always die hard, man. They don't have arms with which to grab themselves and die with drama. They just have to stand there and look down at the holes while their life drains out of them slowly and painfully. It's a cruel way to go, you can bet on that. Sigh . . . A trunk's end is never easy, mate. Never.

GD I know I said Brian was funny but somewhere in this Forum I said you were quick witted. If I didn't say I blame it on Ald-timers disease. Before I started this post I never even considered the feelings of this stump and now I'm thinkin' about holding some sort of memorial service for it.

	I would say  it was a good possibility... Measure the diameter, across the base 9mm is 9mm is 0.35433 caliber, which would not be quite 38 cal, more like 36 cal. Divide the millimeter measurement by 25.4 and you get caliber in decimal inches. All rifled barrels have actually two calibers, the measurement of diameter, land to land and the measurement of diameter, groove to groove. A 0.303 cal (inch) is about 0.308 inch groove to groove. I only read that the so-called 9mm ammo fit the M1 and I used to have some. As for capabilities of an M1, if you can imagine an automatic rifle  shooting virtually pistol ammo, that was the M1, super light and fast firing, but low kill ability. I am quoting, not my assessment. The ammo in the photo is definitely not hollow point, they are too nice and even. I bin a gun-nut since I could walk! goldigger

Ok Gun-nut, I measured again and the round bullet measures VERY near 11 millimeters ( .443) at the base by 16.5 millimeters (.6496) long. The out-of-round bullet measures 10 millimeters at the minimum base diameter and 11.5 millimeters at the maximum base diameter with a length of 16.5 millimeters same as the round bullet.

Ray, I don't have a readily available scale to find the grain so we just have to work without it or wait until I can visit my friend in the mining business.  

Maybe this will help shed a little light. I really would like to know what gun was used here for history purposes (maybe).
Thanks,
Ken

	Weigh it using a standard reloading scale obtainable from any gunsmiths, or just take them in and ask them to weigh them ?? Not hard to do.  :

I've never seen a gunsmiths shop here but I'll ask around. My mining friend has very sensitive scales for gold sales so I'm sure that would suffice

That would be a waste of time when I can weigh it myself, would it not?  What I am saying is *weight does NOT indicate caliber.* Caliber is the diameter of the bore! Weigh that! 

I have 180, and 220 grain .303 cal ammo, and it is NOT 45 cal. Plain and simple. You would have to use calipers and measure the diameter...THAT is the caliber and weighing the projectiles is only co-incidental.

Go figure.
