Default Huh!

While going over new survivor weapons, I discovered something! The M1991A1, "New" Series 70 are lighter than the old M1911A1 and Series 70! Using the 4th rule of 25 grams per oz., the Series 70 and it's usable World War variants are .94kg, the M1991A1 is .78 kg empty compared to 1.05kg on p.248. The new pistol ounce weights are from Colt. Of course the original is Tech Level D, the "Old" Mk IV Series 70 is late Tech Level C, the M1991, "New" Series 70 are made with Tech Level A manufacturing, materials. I wonder if the same is true of the civilian Brownings? Back to semi auto rifles until I can have the book in front of me. AR/CARs, Semi AK's for the most part. Basic single barrel, double barrel shotguns. examples of knives and bayonets to copy. One community copied the Cold Steel Bushman. Cooperville likes KABARs, including the KBD-1. Old scopes and binoculars are going to be included.

Color me a bit confused. Are you saying that the weights listed in the 4th edition differ from real world published specs on the same weapon, that the 4th edition lists different weights based on TL manufacturing for the same weapon or that using an estimated 25g per ounce rather than a more accurate 28g per ounce is making a difference?

Sorry, the 3rd edition put M1911A1's in "Riverton" at 1.13kg empty(p.32) The Armory by Kevin Dockery has 1.106kg empty(p.13), TMP 4TH Ed has 1.05kg on page 248. Page 20 give 25g to the ounce as a ball park figure, I used the more accurate 28. But a quick glance at Colt's catalog online gives 35oz for the M1991A1, 37oz for the Series 70. Older GI M1911A1's are 39oz or 1105g. So either the metals changed or the manufacturing has(Colt retooled a few years back). HP35's were closer TMP4TH has .88kg, the first book I grabbed had .8kg. I'm working on more civilian stuff for Rogue 417 using TMP's rules. Kevin Dockery was an armorer in the army after college, so I'm not surprised his figures were closer. Using 25 to the oz equals 920g for the S70, 28 gives 1010g.

Metallurgy.......... higher tech levels can create stronger alloys and save weight.
