MDT Mention - Impact Shooting 300 PRC HOWA Rifle Build

MDT Mention - Impact Shooting 300 PRC HOWA Rifle Build

The 300 PRC was purpose-built at the request of the United States Special Operations Command (SOCOM) to allow snipers a 50% hit probability on a man-sized target at 2,000 yards. Necking down the .375 Ruger and taking design notes from the 6.5 Creedmoor project, Hornady created a big-bore 30-caliber cartridge that could push high B.C 225-grain bullets around 2,900 fps. Hornady stuck with a .532-inch bolt face and a 3.7 maximum overall length, allowing users to rebarrel a 300 Winchester Magnum if they want to take advantage of this cartridge. The 3.7 maximum overall length allows end-users to take advantage of an AICS pattern magazine. Besides Military/Law Enforcement applications, the 300 PRC is ideal for hunting big game.

Impact Shooting, owned by Pieter Malan, has put out several awesome videos that pertain to the 300 PRC. Pieter took a Howa 1500 300 PRC and built out a complete rifle using an MDT ESS Chassis System. This video is just Pieter building the rifle to some music.

Pieter details the build in this video and discusses his scope choice, the MDT ESS Chassis System, MDT M-LOK weights, AICS Pattern Magazine, Howa Barreled actions, grips, and MDT CKYE-POD.

Pieter discusses loading the 300 PRC in this video. He talks about using Lapua Scenars, accuracy goals, expectations, consistency, neck tension, and some of his loading tools.
