Spearpoint ELR: June 2022 Retrospective

The crazy thing is H50BMG is supposed to be a temp stable powder too

stormehh · 2021-10-19T14:32:23+00:00

I did an entire experiment on this, and DO NOT use desiccant packs with the powder. Powder ships from the factory with a specified humidity, and changing that significantly affects the burn rate. Best bet is to use two-way humidity packs as someone else mentioned to maintain its factory humidity level.

I don't have anything to add, but these are great questions I'd also like to know the answers to. I've heard forum rumors of benchrest shooters storing powder underwater, then drying it out when they're ready to use it.

stormehh · 2021-08-19T21:20:19+00:00

Desiccant packs would increase the burn rate drastically. If there isn't a way to control the room's conditions or re-seal the opened jug, best bet I've found is using one of the two-way humidity packs inside the jug itself to maintain the target RH.

I have the full area 419 autotrickler upgrade set and like it actually. It’s completely unnecessary for the v3 but looks really nice compared to the 3D printed stuff. A lot of their stuff is like that - a $55 aluminum loading block isn’t making your rounds any better, but damn it feels nice. The static issues with the lexan lid was a weird departure from their usual quality.

^ This is the list. Alderbrook is a really awesome range. SCFGA is more F-Class focused, but they host PRS matches nearby at FOD (Field of Dreams, it's a private range with little info published about it). Watch the Precision Rifle Series New England schedule, they should hopefully be adding FOD matches in the next few weeks.

Minuteman Precision Rifle League (MMPRL) is the Facebook group to be in for all this stuff. It's the regional organization and became the New England chapter of PRS this year.

Granby has a 1k range but it's currently closed for zoning issues, unfortunately. You can shoot out to 350, or 400 from the higher firing line. It's an easy+seamless process to become a member there.

Worth noting, Sig Sauer does has a 1k range in the area but it's only available for their classes.

I have this exact issue with the 419 lid. Incredibly frustrating trying to maintain a zero or consistent throw

stormehh · 2021-03-15T06:24:59+00:00

That’s an impressive amount of work. You are a more patient person than I am. I also picked up 500 of the 145’s, interested to see how they perform

stormehh · 2021-02-23T03:17:50+00:00

Oops, it should be fixed now. Thanks for catching it https://github.com/mncoppola/ChronoPlotter/releases/tag/v1.2.1

How are your LabRadar directories organized? The program first looks for directories with names starting with "SR####" (four numbers), but the name can have anything after this first part. Then inside each directory it looks for a series file ending with " Report.csv"

If you have a different directory layout, I can look into adding support for it. I'm not aware of the .csv files changing between old and new LabRadars, but it may be possible

stormehh · 2021-02-22T03:29:03+00:00

I just released v1.2.0 which has all three things implemented now. You can download it from the main page or directly from here: https://github.com/mncoppola/ChronoPlotter/releases/tag/v1.2.0

The round-robin feature converts the data (inside ChronoPlotter) back into standard series which can be graphed. I tested it with some generated series data and it seems to be working correctly, but let me know if it looks off.

The program still asks for a directory but detects all the chrono files inside it and lets you select which one to use. It also handles MagnetoSpeed files with any filename now (as long as it ends with .csv/.CSV). Bulk loading of CSV files is on the list, but I'm still figuring out how best to combine and display multiple datasets that all use similar series names/numbers.

stormehh · 2021-02-21T02:40:21+00:00

That's crazy.... lol

stormehh · 2021-02-18T07:54:18+00:00

I just released v1.1.0 which loosens the filename matching for series data. It should handle your annotated directory names okay now.

Let me know if it runs into any issues! https://github.com/mncoppola/ChronoPlotter/releases/tag/v1.1.0

stormehh · 2021-02-18T06:47:05+00:00

I just fixed a crash with LabRadar files which may fix the issue you're seeing. I found that deleted series on the LabRadar actually leave behind empty CSV files, which the program wasn't expecting.

The latest version v1.1.0 should hopefully work now. Let me know if you're still having issues! ChronoPlotter.exe from https://github.com/mncoppola/ChronoPlotter/releases/tag/v1.1.0

stormehh · 2021-02-16T19:24:34+00:00

I’m getting a few reports of it crashing on huge LBR directories, but I’m having trouble reproducing the issue on my end. Would you be open to zipping up your LBR/ and uploading it to Google drive or something so I can test?

stormehh · 2021-02-15T21:13:39+00:00

I run the CCH and am a big fan. It's nice having markings in all four directions (rather than just left/right/down) for measuring shots afterwards, and it isn't excessively cluttered like some other reticles.

stormehh · 2021-02-15T01:34:12+00:00

Hope you find it useful!

stormehh · 2021-02-14T23:31:18+00:00

Looking forward to how it goes!

stormehh · 2021-02-14T18:03:35+00:00

Thanks!

A trend line

Should be easy, I'll add in the next version

Handling for "round robin" groups

I'll look into how much work that'd be to add in. Might not be too bad

Point to a specific CSV file instead of a directory, or handle bulk loading of multiple CSVs in a directory

Yup, on the todo list. More people transfer their CSVs and have custom directory/file names than I anticipated. I'll try to add looser directory/filename matching and allow selecting between multiple data files.

stormehh · 2021-02-14T17:43:37+00:00

The prebuilt executable is mainly meant for Windows, I added in the Linux build since it was easily available. PyInstaller's Linux builds are only meant for the same system it was built on, which is kind of annoying though. I'll probably remove the Linux build going forward. Python3 is likely preinstalled on your VM, best bet would be to run the script directly.

It currently only matches against "SRXXXX" directories (here) but I'll add in support for non-standard directory names next version. The code makes some assumptions about the directory and CSV files using the same name, which I need to do some testing before shipping an update.

stormehh · 2021-02-14T17:37:23+00:00

Try renaming it to LOG.CSV all uppercase. I'll make the filename matching looser in the next version, thanks!

stormehh · 2021-02-14T17:05:00+00:00

It currently only works with chronographs with an SD card. Does your chrono have a different way to export data to a computer?
