1. Where do I seat the TSX, Tipped TSX and LRX bullets?

We recommend seating these bullets .050″ off the lands {rifling} of your rifle. This length can be determined by using a “Stoney Point Gauge” or other methods. You do not have to seat the bullet at, or on one of the cannelure rings.

2. Twist rate

The twist rate is measured by how many inches of bullet travel down the barrel it takes the rifling to twist the bullet one full turn. This measurement is called the “rate of twist” and is expressed as a ratio, such as 1:7, which means the bullet spins one full rotation in seven inches of barrel travel. The lower the ratio the faster the rate of twist.

3. How accurate is the TSX?

In testing we have found the TSX bullet to be very accurate. Handloader Magazine often prints their test results in which Barnes TSX bullets produce accuracy results that are just as good, if not better than match-grade bullets. A number of shooting schools use VOR-TX ammunition loaded with TSX bullets as their ‘go to’ brand to verify accuracy when a student’s rifle and ammunition does not produce acceptable results.
