2009 FULLBORE Update - Nook
Price:0.99

Although somewhat dated at this point in time, this article provides detailed performance assessment of 8 different .30 caliber bullets weighing under 156 grains (the international weight limit according to FULLBORE rules). This analysis includes the ‘new’ Sierra Palma bullet (2156) as well as the Berger 155.5 grain FULLBORE bullets which are primarily used in modern FULLBORE competition.
300 Winchester Magnum vs. 338 Lapua Magnum WEZ Analysis - Nook
Price:0.99

The specific intent of this WEZ report is to compare the ballistic performance of the 300 Winchester Magnum to the 338 Lapua Magnum with several available ammunition types. Understanding how these weapons compare in terms of hit percentage is important in the context of modern military applications. The recent upgrade of the M24 to the more modern XM-2010 platform would indicate that the 300 Win Mag is here to stay.
300 Winchester Magnum WEZ Analysis - Nook
Price:0.99

The 300 Winchester Magnum is a well established cartridge in the US arsenal. Recent modernization initiatives focused around rifles and ammunition are advancing the effectiveness of this proven cartridge. This Weapon Employment Zone (WEZ) analysis [REF 1] is intended to quantify how the hit percentage of the 300 Winchester Magnum is improved thru these modernization efforts. Primarily the ballistic performance of various ammunition types will be evaluated.
7mm VLD Analysis: Part 1 - Nook
Price:0.99

Berger currently offers two bullets in 7mm: 168 grain and 180 grain VLD’s. The versatility of these two bullets extends from big game hunting to long range benchrest competition and everything in between including long range NRA prone and F-class score shooting. The 7mm 180 grain VLD is of particular interest because of its stellar advertised BC. In part 1 of this two part series, I’ll describe the ballistic properties and performance of these two bullets in a general sense, meaning the information applies to all types of shooting that these bullets might be used for. In part 2, I’ll explore the ballistic properties and performance of the two bullets from the perspective of long range NRA prone slow fire competition.
7mm VLD Analysis: Part 2 - Nook
Price:0.99

Part 1 of this series focused on the fundamental design, stability characteristics, and Ballistic Coefficient testing results of Berger’s 7mm bullets, both the 168 grain VLD and 180 grain VLD. This month, I’ll be focusing on the analysis of those results, specifically in the context of NRA Long Range (1000 yard) slow fire prone competition. The focus of the performance analysis will be on the wind drift comparison between these two bullets.
Ballistics Coefficient Testing - Nook
Price:0.99

All serious long range shooters are aware that bullets have a ballistic coefficient, and that it’s somehow related to how much the bullet will drop and drift in the wind. Shooters place various degrees of importance on knowing the exact BC of their bullets, and shooting bullets with high BC’s. In this paper, I want to explore some of the benefits of knowing precisely what the BC of their bullet is, and also, the different methods available to determine the BC of a bullet. The main point of this writing is to show that BC’s can be measured from firing tests more easily, and with less error than is commonly thought.
BC Testing: Berger .30 cal 155 Grain VLD - Nook
Price:0.99

The purpose of this article is to discuss the ballistics of the Berger .30 caliber 155 grain VLD as measured by firing tests. Such thorough and precise firing tests are a rare commodity for the sporting arms industry. As tempting as it is to dive into the interesting topic of the test itself, only limited discussion is provided on the actual test procedures. The main focus will be on the results of the tests.
BC Testing: Lapua .30 cal 155 grain Scenar - Nook
Price:0.99

Take a detailed look at Lapua’s flagship FULLBORE bullet, the 155 grain Scenar. This report details the physical properties of this bullet including mass and aerodynamic properties, as well as ballistic performance as determined by live fire testing.
BC Testing: Sierra .30 cal 155 Grain - Nook
Price:0.99

Somewhat of a historical article at this point in time (2013), this article takes an in depth look at what was once the standard bullet for international Palma bullet shooting. This detailed article describes the careful testing and ballistic performance assessment of this classic bullet.
Epicyclic Swerve - Nook
Price:0.99

This work was done to investigate a question about the grouping ability of rifles at various ranges. Many shooters, including myself, have observed the strange phenomenon of a rifle that groups angularly smaller at long range than short range. In other words, a rifle that groups 1” at 100 yards grouping 1.5” at 200 yards (you would expect no less than 2” at 200 yards).
