Barnes 115gr TTSX & 127gr LRX Reloading Data

[cory]

I spent a lot of time meticulously loading these, all to see a comedy of errors follow. I got the bright idea to load these into a marked magazine the night before my range trip. The night before turned into 2 months later and I'm not sure I actually loaded them into the sequence I thought I did. I won't make this mistake again.

I'm starting this thread to document my load work up for the Barnes 115gr TTSX and the 127gr LRX. I'm planning an elk hunt out west in '24, so I'm in search of the best possible 6.5 Grendel hunting bullet on the market for my 16" Precision Firearms Bartlein barrel primarily and my 11.5" Lilja barrel as secondary. All intelligent discussion is welcomed as well as any load, range, or on target data anyone has for Barnes bullets.

These show plenty of promise to continue develop. Even if they weren't, I picked up 5 boxes the last time I saw them instock, so I might as well continue.

Loading Data.
Take the velocities from 04/25/23 with a grain of salt. I got distracted with a busy range and PIA finicky magnetospeed while shooting and recording these. That and the aforementioned bright idea. I took all the velocities I recorded, deleted the duplicates (resulting in the expected # of data points), and then sorted them in descending order. This is what you're seeing in the spreadsheet. Based on what I saw from other similar solids on the same day I can use this data to continue my development.

I'm not optimistic due to the velocities vs min opening velocity, but I'm going to continue developing these until I run out of the bullets I have.
