300 Win Mag load development with the Thompson Center Compass using the 168 Berger Classic Hunter and Alliant Reloder 26. Up to this point find a Low SD load has proved very difficult. We implement the Scot Satterlee load development data that we generated previously and use that information to choose our test loads in our journey to find a great load for our Thompson Center Compass. This was a $200 rifle that we are going to test to see how accurate it can be with a very budget setup.

Testing today is with the 105 Berger Hybrid Target in 6mm Creeedmoor. We are evaluating a load using my Ruger Precision Rifle. There is velocity and group data at 150 yards. We use Lapua Brass along with CCI 41 primers to see if these will work well in our Ruger Precision Rifle.

In this video I update the Thompson Center Compass project chambered in 300 Win Mag. This was a $200 rifle that we are going to test to see how accurate it can be with a very budget setup. In this video we go over more reloads in our Thompson Center Compass and updates moving forward. We load up ADG Brass with the 168 Berger Classic Hunter and Reloder 26. Federal FED215M primers are used. We use the Satterlee load development style to evaluate this combo and find a velocity Node to use for our next time with this powder.

In this video we explore a better alternative to 22 Nosler brass. 6mm Hagar Hornady brass can be formed and used with a 6.8 SPC bolt in the AR platform. Much of the discussion and research about 22 Nosgar happens over on the Predator Masters Forums, so that should be your first stop for additional research.

In this video we start our reloading process. We determine the Load Data and COAL for our first loads for out initial reloading and how it was picked. We discuss load data for the Berger 105, Sierra Match King 107 gr HPBT, 110 gr SMK HPBT, 115 gr DTAC for our Ruger Precision Rifle in 6mm Creedmoor. Powders Discussed are Reloder 16, Hodgdon H4350, Hodgdon Superformance, and IMR 4451.

In this video we are evaluating a load using the Berger 105 Hybrid Target in my Ruger Precision Rifle in 6 mm Creedmoor. There is velocity and group data at 150 yards. We use Peterson Brass along with CCI-41 primers.

This video shows the Berger 130 AR Hybrid OTM Tatical loaded with Reloder 16 in my Ruger Precision Rifle in 6.5 Creedmoor. There is velocity and group data at 150 yards. We use Lapua Brass along with Fed 205MAR primers.

This video shows the Berger 140gr Hybrid Target loaded with Reloder 23 in my Ruger Precision Rifle in 6.5 Creedmoor. There is velocity and group data at 150 yards. We use Lapua Brass along with Fed 205MAR primers.

The testing continues as we try 5 different weights of Lumps.

This will be my first post here, so hoping you all find it informative. A bit of background first though. I have been shooting for 40 years, Reloading for 20 years, Precision shooting/Benchrest shooting for about 4 years. I still don’t know a dadgum thing. Every time I think I have had an AH HAH! […]
