Frequently Asked Questions

What makes the 25x47 Lapua a good cartridge for PRS competition?

The 25x47 Lapua is favored in PRS for its optimized ballistic capabilities and manageable recoil. It strikes a balance between the wind-bucking ability of larger calibers and the softer shooting characteristics of smaller ones, allowing competitors to see trace and hits more easily.

What are the key components of this custom 25x47 Lapua PRS rifle build?

The build features a BAT Hammerhead action, a 28-inch CRB barrel, a Foundation Samson PRS stock, Hawkins Precision DBM and scope mount, an Element Optics Theos 6-36x scope, and a TriggerTech Diamond trigger. It utilizes Alpha Munitions brass and an Ace Precision brake.

How was the chambering process for the 25x47 Lapua barrel performed?

The chambering was done on a Precision Matthews PM 1440GT VS lathe using an Alpha Legacy solid carbide reamer with 180 thou free bore. The process involved pre-drilling, boring true, and then reaming to achieve perfect concentricity and headspace.

What kind of accuracy was achieved with the 25x47 Lapua rifle?

After load development, the rifle achieved sub-MOA accuracy, including a five-shot group of .231 inches at 100 yards with Berger 135gr bullets. It also demonstrated impressive long-range performance, hitting targets at 660 and 1390 yards.
