Spreadsheets for Load Development and Range Data

Post by AJMD429 »

Dunno if this is of any interest, but here's some spreadsheets I created to help with load development.

Once the data is typed into the actual spreadsheet, it can be used in the other spreadsheets automatically. I usually load up ten rounds each of ten different loadings, so the spreadsheets are designed around that, though they could be modified for whatever protocol a person wanted.

Image

By entering 'A' through 'J' on this page I can pull up one specific load (of the ten) and look at the data to see if there are any obvious odd-balls that I should legitimately 'skip' when analyzing the data. I can also skip an entire load, if for instance I shot it in a different firearm (as happened with the 300 Blk range session). If I decide to skip a particular shot as an outlier, it is omitted from the subsequent sheets, but can be restored by simply un-checking the 'skip' box.

Image

Then I can look at the velocity trends vs. powder charge for all loads; interesting how much more consistent the loads got with 'hotter' charges, AND how they were pretty consistent with the semiautos vs. the Encore.

Image

Finally it displays ALL the hundred shots on one scatter-graph so I can get an idea once again of consistency and outliers.

I know many reloading software programs do this type stuff, but I just wanted to do it my particular way. If anyone is interested in the specifics, I think I can email the spreadsheet(s).

Forgot to put the one I use to calibrate the powder measure then throw a series of charges:

This one is specifically for my Lee AutoDisk Pro measure but I made one for each of my other powder measures as well. After experimenting though, the Lee was the most consistent (vs. Dillon RL550 and RCBS Uniflow) with the small AA-1680 charges around 9 grains or so. The spreadsheet allows me to quickly see how 'linear' and how reproducible the thrown charges are.
