25 Creedmoor Build Success

25 Creedmoor Build

Aaron C. of Idaho sent us some photos of his recent 25 Creedmoor build using a Shilen Rifles, Inc. barrel purchased from Northland Shooters Supply (NSS). Here is what Aaron used on his build:

  • 28” Shilen Stainless Select Match- small shank- heavy Palma barrel with a 7 Ratchet twist and muzzle thread
  • Zermatt Arms/ Bighorn Arms Origin action
  • TriggerTech Special Stainless trigger
  • NSS squared and trued barrel nut
  • Forster Products headspace gauges
  • NSS Cerakote on the barrel and nut
  • KRG Chassis

Here is what Aaron had to say about his build.

“I didn’t have a chronograph or modified case so I just guessed on charges and seating depth (2.842” COAL) but this barrel is a shooter!  Yesterday at 300 yards it shot .250”-.330” MOA all the way from 41.4-41.8 grains of H4350 powder through the first 20 shots on the first day of load development even with a little wind.

Load was:

  • Lapua 6.5 CM small rifle primer brass necked down
  • Hodgdon Powder H4350, tested 36.0 – 42.5 g w/o any pressure (10-20 degrees F, 4,200’ elevation)
  • Berger Bullets 135 grain Long-Range Hybrid Target bullet
  • CCI 450 small rifle primers
  • 2.842” raw length (no modified case yet) 

At 300 yards: 41.4, 41.5, 41.6, 41.7, 41.8 grains of powder all shot roughly .33 MOA or better. With 41.5 grains of powder being right at .2502” MOA from shots #26-50 on the barrel.”

After Aaron got his chronograph back he sent us the above picture and here is what he had to say:

Here’s my three shot group today with a SD of 0. Shot at 100 yards. Velocity (from MS) was 2891, 2892, and 2890 FPS. Shot off a bipod and soup can bag. 41.5 grains of H4350 Hodgdon Powder, Berger Bullets 135 Long Range Hybrid Target bullets, and CCI 450 small rifle primers. I’m loving my 25 CM thanks again
