Grendel Pistol build

[danm]

Here is a cut and paste from an old thread:


10 shot strings...

10.5" Grendel without suppressor
Hornady 123 Amax factory load (1st batch)
Lo- 2155
Hi- 2212
Avg. 2179fps
ES- 57.67
SD- 16.64

10.5" Grendel with 762SD suppressor
Hornady 123 Amax factory load (1st batch)
Lo- 2171
Hi- 2216
Avg. 2198fps
ES- 45.11
SD- 12.68

Weather was hot and the chrono was probably about 12-15 feet. I don't have the details because I always posted everything to the board from my post-it's and/or scrap paper. I suck at record keeping, because I counted on using the board which some bastard crashed...

10.5" Grendel
Wolf 120gr. MPT without can--I think? (we're literally talking written on the back of a receipt here....)
Avg. 2101fps
ES- 76.89
SD- 23.28

On the same slip it lists the 123gr. Lapua AA factory load as:
Lo- 2099
Hi- 2177
Avg. 2148fps
ES- 77.47
SD- 22.09

Hopefully that helps.

Thanks Variable, it really does!

BTW, here's what my 5.56 pistol looks like...
