Grendel takes it's first life

[Brett A]

I broke my new Grendel in the right way this weekend. This guy made it five steps before he fell.[ATTACH=CONFIG]8291[/ATTACH]

Man I like the looks of your build!!

[Brett A]

Thanks. My second AR, but the first one I put together from scratch. I know there are nicer ones out there, but this one suits me fine.

Congrats! If you haven't already please consider entering your results per the format in the Hunting section game survey so we can add this one to the record.

Nice job! What load?

[Brett A]

123 gr. SST on top of 31 gr. of CFE

123 gr. SST on top of 31 gr. of CFE

That's close to one of my go-to loads, which is 31.2gr of CFE under the 123gr SST or AMAX. Pressures are in the 46,000-47,000psi region with 31.2gr at 2.245" COL with a SAAMI chamber.

31.9gr is the max load with 123gr SST or AMAX, if you cut off at 50,000psi.

Is that an 18" barrel you have?

ETA: Corrected pressure numbers.

[Brett A]

no, 16 inch

Nice one!

Great job!

Does the CFE seem to keep your barrel pretty clean free of copper?

It does mine, even with Nosler ABLRs.

Slamin Hamin!!! BANG BANG!!

I just cleaned my Shilen barrel yesterday with Shooters Choice copper remover. My Shilen 6.5 G barrel showed no indication of copper on the patches. This barrel has shot Nosler 123 grain CC with CFE 223 powder almost exclusively. I haven't shot as much CFE 223 powder in my 16" 6.5 Grendel but it showed just a small amount of copper discolration on the wet SC patches.

Would you mind sharing your barrel length, charge weight and velocity?

I recommend 2.260" for most and no more than 30.4gr of CFE223 if you want to stay at 50,000psi working pressure.
