New Web-Based Interior Ballistics Calculator – Precise Load

Hey everyone,

I’m Benedikt, a reloader from Germany, and over the past 1.5 years, I’ve been developing https://preciseload.com as a spare-time project. Precise Load is a web-based interior ballistics calculator, similar to QuickLOAD and GRT, but it runs directly in your browser—no installation needed.

Thanks to Lowlight’s approval, I’m excited to introduce Precise Load here and get feedback from the community.

Key Features:
  • More Accurate Simulations – On average, Precise Load predicts pressure and velocity levels more accurately than QuickLOAD and GRT.
  • No Installation Required – Any device with a browser works—I recommend using something with a larger screen for a better experience.
  • Public Bullet Database – Add and share bullets using Precise Load’s simple bullet measurement tool.
You can try it out here: https://preciseload.com (registration required).

I’d love to hear what you think—especially regarding usability, accuracy, and any improvements you’d like to see.

Looking forward to your feedback!

Benedikt

GPO scopes

Hey guys I'm looking at scopes and am trying to figure out what to do with the GPO stuff. I can't really find any in depth reviews or comparisons. The few basic reviews I've seen say they're really nice but that doesn't actually say much.

I have my eyes on an arken ep5 or an athlon helos BTR Gen 2. Is it in this same tier? Can any of you guys elaborate on how it might compare?

(SecDef Nominee) Pete Hegseth Interview w/ Shawn Ryan

This should be interesting.

On Accountability...
“[G.I.] Joe also knows that if he loses his rifle, he’ll be demoted immediately,” he wrote earlier this year. “But if a general loses a war — or billions of dollars of military equipment — nothing happens.”

SOLD Price Drop - Steiner C35 Gen 1 640 Thermal Clip-On + Extras

Unit is in excellent condition and has only seen range use. Comes with everything it originally shipped with plus the following extras:
- Two 18650 batteries (total of 3)
- Burris magnified eyepiece to use as spotter
- Vortex Defender scope caps for ocular and objective
- Extra mount -I had one rail that I felt the original mount wasn't tight on so I had Steiner ship me an extra. I then added strips of tape between the metal strips that compress when quick-release lever is engaged. This tightened up the mount for the slightly undersized rail. Mount that is not currently attached is 100% factory.

$Sold shipped to your door anywhere in the lower 48. Not looking for any trades at tjis time. Thanks.
