How to Use Chronoplotter to Plot Powder Velocity Test Data in No Time!

[@touchgo7281]

Thanks to John for bring this to light and Michael Coppola for open sourcing this fantastic program! Thanks both of you!

[@Anon.Emouse]

Wow, as someone who's been doing this in excel and struggling sometimes this looks like a great tool. Edit. I just downloaded it and was able to do in about 20 seconds what took me half an hour in excel. Love it. Kudo's to the developer.

[@FClassJohn]

Glad you like it!

[@mrbreakit6063]

This is huge! Incredible time saver. No more cut and paste, mixing up files, then forgetting the data card in the computer while at the range... all with intuitive logical graphing. Amen. Thank you so much for sharing this, and a big thanks to mncoppola for making this program.

Is there going to be an update to cover the Garmin Xero Pro in the near future?

I honestly don't know but I'm hoping so too.

Thank you for dong this video. Extremely helpful.

holy crap this will make is sooooo much easier then having to try making graphs with numbers in the iMac.. Like the ability to get the data off the Labrador memory directly.. A+++

Exactly!!

super curious to why you said "I don't care about SD". if there is a reason I should stop looking at SD an focus only on ES id like to know., thanks and great video. id almost like to see another in-depth with this program. cant wait to try it.

Awesome.. thanks for sharing!

[@somedude5713]

John, I reached out to Micheal Coppola to add data from the competition electronics chronograph, i sent him some samples. I also mentioned importing data from the shotmarker for seating depth section, he said he was looking for some sample exports, I dont have my shotmarker yet, so I cant get him any, any chance you could send him some shotmarker csv exports?

[@snajjpern]

Can you use the .csv files from the magnetospeed sporter, the same that you can mail as backup from your phone when using the sporter and xfr cable? Or do you need the MSV3? Thanks for a great channel🎯

[@that_guy_you_hate]

Yes you can use the sporter csv file

[@Foxer223]

As I’m new to reloading would you choose 50.6 or 51.1? Obviously I can see that the 51.1 has a lower e/s, but is the 50.6 better because there’s less of a jump In between the loads?

[@FClassJohn]

Yes exactly.

[@stefanwhite1013]

Can you enter in your velocity’s manually?

[@michaelcoppola8187]

Hi, I’m the developer. Not currently, but it’s on the to-do list to add something like that. I’ll let you know if it makes it in a future version.

[@glockparaastra]

@@michaelcoppola8187 I'd like that too. I don't own a Labradar or Magnetospeed. Manual editing of data would be great! Thanks

[@hbudsmalley6317]

I just downloaded this and can't get it to work. Says I need two series. Was hoping to plot a graph from a ladder load test.

[@Anon.Emouse]

Question. Is it better to do 10 5-shot groups or 5 10-shot strings when ladder testing?

[@FClassJohn]

I don't know about best, but I always advocated for five shot groups.

[@markahdz]

If you want to save some components you can start by testing charges to find the flat spot, usually the high spot its around 1- 1.5 grain under the max, but like always you need to test on the safe side, so you start and do increments of .2 grains once you found the spot then you can play with more shot groups on those chargers and also seating depth.

[@bartoszwilk1382]

Thanks John. But what IF there is no flattening at all? Do You just watch the grup sizes or change the powder or primer?

[@graynotescartridgebox]

I’m not John, but I’d be changing powders first unless I was using one of the mainstays that should work for my cartridge. For instance a 6.5x47 that won’t shoot with H4350. If I was already using one of the best powders, I’d experiment with a different primer and rerun the test. I actually experienced this with my 6.5 PRC. I had no nodes to speak of. I also had no pressure signs, though I was at max charge. I’d done some reading and found the brass I was using wouldn’t get the same pressure as the published brass. I ended up working 1.5 gr higher and found a huge node just above where I’d stopped with the first test. I’m not advising you to go over published load data, but it did work for me.

[@FClassJohn]

As Graynote said, I'd change things in some way until you find a flat spot. No flat spot indicates any number of things because there are always nodes and there will always be flat spots along those nodes. It could be poor brass prep, wrong powder, wrong powder charge, bad ignition, bad brass or any number of other things. First thing is make sure your ES numbers are under control and go from there.

[@patruddiman4228]

Does a person always have to load 3 rounds for each powder charge?

[@FClassJohn]

No, I normally do 5 but with powder running low I did a quick test to verify something and thought it'd be a good chance to do the video. 5 is really what should be done for really accurate results in my opinion.

[@patruddiman4228]

@@FClassJohn The test that I will be doing is for a Browning X-bolt hunting rifle. I see in your test you did 1 tenth of grain increments. I've always done 3 tenths because that is what I saw in previous KZbin videos. So I only shot 1 round for each powder charge. My biggest problem is I have plenty of powder and primers but low on bullets and I can't seem to find any unless I go to gun broker and pay 3 times the price.

[@FClassJohn]

@@patruddiman4228 I'm not a big fan of doing 1 shot tests and as it is, I don't like 3 shot tests. Wayyyyy too many variable for it to be an accurate test I think. I know there's people who advocate for it but all it takes is one mistake or bad seating pressure or anything like that and the data is corrupt. But everyone does tests for different reasons so maybe for what they want to achieve it makes sense 🤷🏻‍♂️.

[@michaelcoppola8187]

Hi, I’m the developer. Sorry you’re seeing this issue! Most likely what you’re seeing is a SmartScreen warning, it’s a standard warning Windows 10 shows for programs it hasn’t seen before. It should likely go away by the next couple days. Alternatively, you can click "More info" and "Run anyway" to run the program without waiting. If there’s still concern, you can submit the program to VirusTotal and see that every antivirus marks it safe. Let me know if you have any questions, happy to explain further

You may want to go to the Long Range Hunting blog and see the /labradar-great-data-terrible-implementation-partial-solution-inside.221826/ thread.... It explains how the labradar just SWAGs the V0. The regression modelling corrects for this... but you would have to enter the data by hand. You are getting a manual entry program prepared, correct? Thanks so much! WillyB
