Bullets

If I drop a bullet on the floor or ground it goes in the trash. It could pick up embedded grit and I don't want to fire lap my barrel, even for a fouler.
 
Experiment...

Try both heating some in a hot oven and/or chilling in a freezer (or colder) and see what difference it might make. Results might prove interesting.
 
In short ranges BR minor variations in weight seem meaningless at the target. I truly wish it was that easy to sort the good ones from the not so good.

Since this is Benchrest.com. I assume we are talking about custom bullets, out of the same die, all made at the same time by an indivudule who knows what he is doing.
That does not include such "match" bullets as Hornady, Sierra, and other mass produced offerings.
While I have not done it lately, in the past, when I did take time to weigh true match bullets, they were within the tolerance of my scale.
I had the loan of a Juenke Machine a while back, and checked several brands of custom bullets. All showed about 3 to 4 "lines of deviation", (what ever those represent), except one particular bullet. That was the BIB. When placed on the machine, the needle would just kind of quiver. While this does not prove anything in particular, the fact that the BIB sort of sets the standard in 30 caliber bullets does.
As for using a dropped bullet. Come on, guys. We spend hours at the range, THOUSANDS of dollars on equipment, not to mention the ever increasing cost of getting to matches. Many of us go to matches with on intention. To Win.
I would no more shoot a dropped bullet on my record target than I would use a dropped case with a bent neck. I can use it to fireform, or to foul the barrel. But in this game, worrying about saving a 25 cent bullet just doesn't make much sence in the whole grand scheme of things.........jackie

There is alwys a certain amount of tinkering you need to do with a new lot of jackets. I've got a certain base-to-ogive figure that I like to stay within, so I use my 'setup' bullets as foulers and fireform bullets. I call 'em my 'in the berm' bullets.

Dropped cores don't go in my squirt die. And a dropped jacket will never get a sniff of the inside of my core seat or point up die. A dropped bullet just joins the rest of the 'in the berm' gang. -Al

Bart i have seen the same thing'' 66gr gr in the same hole as 68 gr
bullets. still i hold my tolerance. {It makes me feel better}
The wind has more to do with the group then the bullet.
great wind doping is just that great wind doping.
my bullets:D:D were measured on a machine that is far more accurate
The a junkel machine {medical equip lab }
The run out on the spin is really low about 25 millionths.
but then again CLYDE HART told me the best way to spin a bullet was down the bore:D
