Triggered Precision Machine - Custom 338 Lapua Magnum - Extreme Long Range Rifle Build Review (ELR)

Howdy!

I felt like this would be a rifle review that might interest a few of you long range shooters out there, especially those who are looking to get into the shooting games that stretch out past 1,000 yards.

This particular build came with a lot of thought and planning. Caliber selection was a tough one. There are several good 7mm, .308, and .338 caliber cartridges out there that perform great out to 2,000 yards and beyond, but we wanted to potential to push it a little further. After kicking around the idea of going to David Tubb's 33XC or even the 37XC, we opted to go for an "improved" version of the .338 Lapua Magnum. This version is my custom chamber reamer spec. and includes 40 degree "Ackley Improved" shoulders and a generous freebore for monolithic bullets and heavy 300 grain copper jacketed slugs. We will use standard Lapua manufactured brass to start and fireform the brass to match the new 40 degree chamber shoulders. This cartridge should get us to 2,500 yards without too much difficulty, and we benefit from great component selection and a substantial amount of reloading information already out there!
