Ultra-Tech Gun Noodlings: How to Figure Bulk and Magazine Length

Sup fam. Got some quick but tasty nuggets for you today.

First off I've come up with a way of figuring a weapons bulk that gets good results. This is NOT official by any means but it seems to work. It is a bit fiddly though. 

First you're gonna have to fi
gure to values:

Bul and Buw.

Bul is based on the weapons length in millimeters and can be figured as:

6 × LOG₁₀(Wl/305) + 2

Wl is the weapons length is millimeters. 

Buw is based on the weapons weight (unloaded if mounted) in pounds and can be figured as:

2 × LOG₁₀(Ww) + 2

Ww is based on the weapons weight (unloaded if mounted) in pounds. 

The weapons actual Bulk then can be figured by taking the average of Bul and Buw and then slapping a negative signto it. 

For example: A FAMAS G2 is 757mm long and weighs 8.4lbs. This gives us a Bul of 6 × LOG₁₀(757/305) + 2 or 4.4 and a Buw of 2 × LOG₁₀(8.4) + 2or 3.8. This gives a Bulk of (4.4 + 3.8)/2 or -4. While there are no stats for a FAMAS in any official book, HANS was kind enough to provide the forum with a write up and sure enough it's bulk is -4. 

 And while we're here, might as well throw in a quick way to estimate a magazine length, just so you can get an idea if your magazine modification is practical (and should let you know you're not going to see a huge increase in the number of caseless rounds a standard magazine can hold).

Magazine height can be estimated as number of rounds × rounds actual diameter (this might differ from the listed one, a 5.56 NATO round is actually ~5.7mm) × the polymer/plastic magazine type weight modifier for a given magazine type found on High-Tech p.155 under Extended Magazines. Multiply this value 0.7 for curved magazines like most military rifles use.Adjust the height by +/-10% as needed.

Why am I getting some casting couch energy form this pic?

For Example: a 20 round magazine for a FN Five SeveN is about 126mm (~5 in.) tall. The actual diameter for the round is 5.7mm and used a high-density magazine which has a polymer/plastic weight modifier of 1.1. This gives us a height of 20 × 5.7 × 1.1 or 125.4mm (4.9 in.). Close enough for government work.

So why am I thinking of gun stats all of a sudden? Well, I know, bad question. When am I NOT thinking of gun stats after all. Well I may or may not be working on expanding the kinetic side of Ultra-Tech firepower in my next few posts. I do hope to get some stuff out soon but I am also working on some non blog related projects so  maybe that might be more on the soonish side of things but they'll get there.
