Riddle me this Batman

[Bottom Fodder]

I was watching a video of a nation bench rest match which theses shooter are known to cross all their “T’s” and dot all “I’s” during an interview they talking about they load by powder volume not by weight I had heard that before. So I’m assuming it’s more accurate? So my question is why don’t Fclass shooters do that. I know both will sometime change to a different for the conditions that not what I’m talking about.
This should be interesting

This is a great question, as I have read many 100-200 yd benchresters use the same Volume method over weight.
which to me does not compute
given the powder can compact depending on how hard you cycle the powder measure
or how much powder is in the hopper
----how can a guy keep consistent Volume?
When weight will always be a finely measureable constant.

Sounds like it's pretty outdated as most Benchrest competitors now weigh their charges. At the East-West Shootout in St. Louis a couple of weeks ago, I would estimate that 95%(or more) were weighing every charge.

I think by volume only applies short range benchrest? guys who don't preload for matches so they can adjust during match...
I imagine most mid and long range benchrest guys preload..

I have a suggestion. Take a look at the short range group records for the IBS and NBRSA. Gary Ocock owns six or seven of them, many quite recent, and consider that all of the charges he shot and continues to shoot are thrown directly from a powder measure directly into cases. Long range is different than short range. I do not think that weighing charges for short range hurts anything, but for at least one shooter it has not been a requirement. I have spent a LOT of time experimenting with throwing charges, to find out how to do that with the most consistent weight. After all of that, I advise new short range shooters to buy a Chargemaster, because there are a lot of subtleties involved in throwing the most consistent charges, and the effort that that takes would be better spent learning how to tune and read wind flags.

Some powders go very nicely through a powder thrower, and some -- suck.
Those ones that suck, I'd want to weigh. jd

 

[jwv2001]

That's the way I do it. The only thing I would say is to try it and see how it works out for you. I'm definitely not trickling powder anymore.

 

[DShortt]

Watching to see how this develops. Some stick powders are a real pain to get through the powder measure with consistent weights.
Maybe I should try a volume measure and check the weights for verification......

Which is just what a powder measure and weighing charges for verification does.

Huh.

 

[jds holler]

I AM NOT A COMPETITION SHOOTER!

but the way I've been doing lately with a Staball powder which is very nice to work with is --

Put my empty case on the digital scale and zero the scale.
Take the case and fill it at the measure. (clink clink-clank clank)
Put filled case back on the scale.
Scale reads plus/minus .1 gr. of my desired weight - good to go. If error is greater, I just dump the charge and throw another one. This particular powder is almost always within .1 grain, and frequently dead on.

When doing it like this I'm also able to keep my eyes open for a case that is crazy high or low in weight, and get it out of the line-up if I want. jd

So basically my ? Was answered, this practice is only use in short range BR and not used in long range so basically that is why not used for F class, but good to know that is STILL being use by by recorder holders. That lets me know it WAS a legitimate? To ask
But still would like here any comments on this subject we all might learn something helpful
Thanks for the reply’s carry on

I've never had trouble with ball or flake powders. Stick powders are like what Bobby Boucher's Mama said, 'The Devil!'
Wish I could figure out how to get them to throw consistently. No luck so far.

Agreed, but you have to admit that Gary is the exception.

I was referring to short range BR as that's all I have first hand experience with. Most of us are weighing these days.

Bottom Fodder -

Howdy !

What you are talking about can be viewed as one shooter stating that his powder charge was XXX amount of “ clicks “ , while another shooter expresses his charge as being XX.X number of “ grains “.

I believe there’s even a request stated somewhere here on the site, asking shooters to convey info on the cartridge’ powder charges they used to the readers; by stating it them in “ grains “.


“ Take that, with 1.0 grain of salt “…


With regards,

Has anyone tested the variation in case capacity from case to case? Does it vary as much or more than the consistency of the powder charges thrown from a good measure? Would it matter on target?

 

[quest450]

I compete at 600 &1k where case capacity is probably more important than in SR, recently checked my 7x fired 6BRA sized, primed and trimmed cases using Bison case capacity software looking for outliers but didn’t find any in my 200 lot

This may be a "controversial" thought, but here goes - if you don't store and monitor / manage the humidity of your powder, the dispensing by volume may very well have an advantage. "wet" powder absorbed water - they weigh more, but their volume stays the same - so if you dispense "wet" powder, you will throw less kernels and get less velocity.

I like “controversial thought” that can lead to a better way of doing things SOME times
