Barnes 127 LRX Gel Block Test
Welcome back to the ballistic gel tests series as I dive into the Barnes 127 LRX.
I had been searching for multiple different types of bullets that I could use in .264 that was non-lead. Ultimately, so I could hunt in states that only allowed specific types of ammunition.
With so many choices, I decided to try out the 127 LRX.
Moreover, let’s dive into this projectile and look at some of it’s specs.
The first thing I wanted to see, is how well a specific bullet will perform, compared to what is advertised.
Of the same lot of bullets, I selected 100 projectiles at random to test the dimensions of each individual bullet. Here are the results below:
Very accurate results. However, like all projectiles, they will either produce a ton of variation or very little. Here’s another similar article I wrote on the 140 Match Burner which had produced similar results. Moreover, this projectile had produced less variance than the Match Burner, which, is typical of copper projectiles versus traditional projectiles.
With a published .264″ diameter, I was seeing 0.26394″ consistently across the board. In this case, off by 0.00006″.
The length is advertised at 1.399″, in which I had found my specific lot to be 1.4034 on average. Only a 0.0044 difference!
Published at 127 grains, I found my lot to be 127.12 on average. Only a 0.12 grain difference, which, is great.
Load Workup for the Barnes 127 LRX
As an avid user of Shooters World, I have found their powder, Long Rifle, to yield exceptional low SD, ES, and produce great nodes. If you had read my last article on the Match Burner, I had mentioned that this powder also has virtually no muzzle flash. It is a short cut extruded powder, which ultimately works great in volumetric powder throwers because of it’s kernel characteristics and properties. Plus, it is temp insensitive in my testing of it.
I first want to mention the long stretch in the data. I reload at the range in an enclosed area. After reviewing the speeds, I wanted to jump to a higher grain of powder to see if I could find more nodes. I found a good node at the end, but was running pretty hot. Slight bolt lift, nothing too crazy. Primers looked fine. However, when hunting at different times of the day, even with temperature insensitive powders, velocity will rise slightly. Given that this was conducted at 72 degrees, I played it safe and opted for 39.7 grains with a 2823 average velocity. Among that, It produced an SD of 3 and an ES of 5.
Please keep in mind, the suggested maximum powder charge weight, according to Shooters World, is 41.5 grains with a 129 grain Hornady SST going 2747 FPS. If you do copy my load data, please workup in very small increments and be aware of any pressure signs that might show with your reloads.

So, what all components were you using, barrel length, build, etc?
Here’s my hand-loading equipment and components listed below for those who are interested. If not, just skip on down to the rest of the article.
1. Grayboe Ridgeback with DBM
2. Remington 700 action
3. Criterion Remage Drop-in 26″ 1/8 twist
4. Vortex Optics Razor HD Gen 2 4.5-27×56 EBR-2C
5. Deadair Sandman-L Suppressor
6. Magpul AICS magazine
7. Burnproof Heavy Suppressor wrap.
After confirming my load development at 39.7 grains yielding 2823 FPS, I was able to produce a group of 0.376″-0.26394= 0.11206″ grouping with 5 shots. Pair this with the exceptional low SD and ES, I’d say this is one hell of a tack driver ready for hunting.
