How much bullet weight is necessary

[Gumbeaux]

To strictly address the weight of an object in a fluid, one needs to know 2 things - the weight of the fluid (fresh water is 8.33 #/gal) and the objects' weight in air.  Each fluid weight has a buoyancy factor where  BF = 1 - (fluid wt/ gl divided by 65.42).  Multiply the object weight in air by the BF and you will have the weight of that object in that particular fluid.  The buoyancy factor for fresh water is .8727.

Well now...

Just enough to be enough, but not so much it’s too much. And not so little it’s too little

You had one? I thought I was old enough to have seen most things, but have never seen a calculator like that?

Ya - Junior High...which would put it early to mid 70s. Then dad got me a TI-30 when I started High School

It you want to understand buoyancy I suggest you ignore the "science" in this tread and find a good youtube video on the subject.  YOU CANNOT DETERMINE THE WEIGHT OF AN OBJECT IN WATER WITHOUT KNOWING HOW MUCH WATER THE OBJECT DISPLACES.  

 

According to Archimedes' Principle:

Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

 

Most boat owner have learned this lesson by launching their boat without putting in the plug.  The boat's weight doesn't increase without a plug but's the amount of water it displaces changes drastically.  I've learned that my boat floats much better with the plug in.  ?

What?  If you put a container of water on a scale and it weighs 100 lbs.  Then drop a 1 lb. bass in it the scale will read 101 lbs.  The object's mass doesn't change.  I'm not sure where the object's volume would fit in, but I have often joked that displacement would be THE MOST accurate way to determine whose fish is bigger.

X2 lol. I even remember the little white stick that came with it.

I agree if you add a pound to the contents of a container then the total weight of the contents of the container will increase by one pound.  We're talking about buoyancy,  that's the weight of the object as measured by a scale inside the container under the water.     Here's an easy science experiment.  Put 10 lbs of lead weights in a half gallon jug and tie a string to it.  Do the same with another 10 lbs of weight in a gallon jug.  Be sure to put the top on both jugs to keep the water out.  Use your favorite fishing scales to confirm that both weight 10lbs.  Now lower both into the water by the strings and measure the weight of each by attaching it's string to your scales.   Do you think the weight on the scale will be the same for both 10lbs jugs?

[Choporoz]

Haven't met a bass that said size of my sinker matters.   Physics and other mumbo-jumbo aside....I base choice of weight for Texas rig a little different.  Probably due to my lack of experience relative to @Catt, for example,  my confidence sweet spot is more on the bottom bite than the 'fall bite'.  I recognize that ROF is important,  but usually for me, bottom and cover/structure feedback is most important to me.  It doesn't take a whole lot of wind or current for me to almost disregard ROF.  I want a weight that comes through wood (or vegetation) fairly cleanly, and gives me information about what is going on down there.  Often that means 3/16 tungsten....but sometimes it means 1/16 lead...or 5/8 tungsten

You’re putting a container of water on a scale and weighing the contents. He’s putting the scale in the water and measuring objects there.
 

He’s right, an objects weight in water is a function of its density. 

[Deephaven]

Concept was right, wording made it read wrong.  Weight in water depends on buoyancy as well and for that you need the density.

[J Francho]

You guys had funky science teachers.  So a steel ball that weighs 10,000 lbs. has the same density as a steel ship that weighs 10,000 lbs. yet one sinks and the other doesn't.  Weird, because they have the same density, volume, and mass.  Seriously, though you can't simply mix and match concepts to suit your argument.  I have no clue what any of this has to do with the bullet weight on my Texas rig and the fish (that's bigger than yours :P) that's on the hook.  A fish is incapable of determining the difference between a 1/8 oz. and 3/4 oz. bullet weight and the any angler that says they didn't get bit because they used the wrong weight is fooling themselves.  If you got bit using 1/2 oz. tungsten and then no bites using 1/2 oz. lead, I'm going to tell you this: it wasn't the weight.  I mean, probably, maybe, or not.  Profile, fall rate, and the action of the bait is all influenced by what weight you choose.  Most importantly, where you put that bait is the key factor in getting bit. 

[Tennessee Boy]

If we're going to bring up funky science teachers.

 

 

[WRB]

10 lb bass in water is weightless..it suspends because of it’s air-bladder.

Recommend using a bullet weight that weighs enough to feel the bottom to start with. Over a 1/2 oz consider tungsten.

Buoyant sinkers - sounds like an oxymoron.

 

This has been weighing on mind in a massive way.  It's displaced all my other thoughts.  I wish the problem would float away, but I have sinking feeling it won't.

If this has you all messed up, just wait until I introduce my newest "floating tungsten" line of sinkers and jigs to the bass fishing world. Taking prostaff applications now

When you stumble into a thread and intrude on a physics debate when you just want to fish

 

 

[Boomstick]

@Bluebasser86 said it perfectly.

 

Most of the time it's going to be 1/8oz or 1/4oz for me too, but if I'm fishing on a MH rod then 1/4oz usually gets the nod simply because it just casts a Powerworm or Senko significantly better than 1/8oz on the same rod and it gets down quick enough for most situations but not so too quick for shallower water. If you're targeting them solely in deeper water, you might want to go up. Sometimes they hit it when it falls faster, and sometimes slower is better.
