In mathematics the range is defined by the largest number less the smallest.

From 32.5 to 32.6 is 0.1 grain and from 32.6 to 32.7 is 0.1 grain. You cant add 0.1 and 0.1 and get 0.3.

As a good buddy of mine once told me....I can explain it to you but I can't understand it for you

I got a feeling I know who your good friend is.

Its funny to me, at least right now when I think im right. The maximum error is .2 grains.

And if you're in the node that variance is hard to notice. That being said single digit sd is easily achieved on a rcbs and is more than sufficient for everything except br or f-class as most can not shoot much less read the wind of the difference between a 15 or lower sd vs a single digit sd.

At Rifles Only this weekend, I had a guy heavily argue with me that a round needed outside oxygen to burn, ignite and fire a round. I said no, gun powder has an oxidizer in it and does not need outside oxygen to fire. That's how it is able to fire under water. His answer- oh, there's oxygen in water. I laughed and said go jump in the bottom of the pool for 3 minutes and then tell me there's oxygen in the water. I then laughed and walked away. Some people always "think" they are right.

Some of them are right too.

He is right to a degree... there is plenty of oxygen in water... you know, H 2 0

I have no idea, would gunpowder burn in a vacuum?

Even if the powder has an oxidizer on it, I don't know what that is other than a substance with oxygen in it. Would a primer fire in the absence of oxygen?

No kidding?

Key word "USUALLY".

go jump in the bottom of the pool for 3 minutes and then tell me there's oxygen in the water

Redchevy if your load is 44.5 and it’s a +/- .1 then that would be 44.4-44.6. I don’t understand what you don’t understand.

Are you just arguing at this point?

I know that guy!!!

^^^ This.

Either trolling or not too smart. Been several months, and I still have not figured out which.

Well for the sake of being right yes I am arguing. I don't know how yal don't get that the intended number isn't and error. With an accuracy of + or - 0.1 you do not get a RANGE (this is a mathematical term, look it up) of 0.3. You get a range of 0.2, or 0.1 below and 0.1 above your intended point. Some of you may like to think you know the answers to world peace and hunger but you aren't God and you don't know everything. I have several very bright people who know their way around reloading arguing a point they are wrong on and trying to make me sound like the stupid one lol. Someone should be the bigger person and admit they are wrong.

I guess calling a disagreement trolling is the only way to admit your wrong or there may be another way.

They have made rats breath under water.

Oh I don’t think your trolling I think you believe what you’re saying.

Me? Just me?
Do you see several other smart people here telling you that you are wrong? Yet again...

I get it now...no disrespect but I have no other way to describe it except you're thinking like my wife....which is backwards.

The Maximum ERROR is .2 (one up/one down) but the men here are talking about Maximum RANGE which is .3 and a chargemaster can give you a reading and it's within a .3 RANGE.

Does that help your understanding? and yes...you might have run into him

Yes I see them. I believe they are wrong if they think the range is .3

You are using the term range incorrectly, my man

I’d also like to add I’m supporting my side in a way other than implying yal are invalids

I know good and well my particular Chargemaster has a range of .15 gr low, and .15 gr high.

.15
+.15
=3.0

I know this because I set the Chargemaster to throw 42.4 gr, and moved the pan of powder to a beam scale. Then I counted kerbals of H-4350 I had to remove with tweezers, or trickle in by hand. I documented 20 throws, and made a post about it here.

Months later I obtained an FX-120i that does measure to .02 gr. It confirmed the data I made with the beam scale. My Chargemaster has a .3 gr error.

No he's not

Minus .15
Plus .15
Is a .3 range, total.

Shoot one loaded .15 light, and the next one .15 heavy, those two shots were loaded in a range of .3 gr.

I use the CM Lite, it has sped up my reloading and has made better more consistent loads over my previous method. Which was using a dipper spoon and manual trickler on a Hornady digital scale.
