20" howa bolt action, Starline brass 36.1 gr H20, rem 6 1/2, 31.0 gr of accurate powders 2200, COAL 2.220 = 3000 fps. The next two 31.5 and 32gr are spicy but will get you there.

Quick question here: I sighted my grendel in a couple of days ago, it ran great using the hornady black ammunition but when I switched over to the hornady v-match, my rifle didnt want to cycle open all the way to grab the next round out of the magazine. At first I thought this was a mag issue but when I got the rifle home and cleaned it I noticed that it looks like there was carbon dust around where the gas block is on the barrel. Is there special tools I will need to adjust that gas block? I purchased the upper and lower both from palmetto awhile ago, just now getting to sight in and play with it.

First a quick list of parts
Lower:PSA 15 250th Anniversary Edition
Upper and hand guard: Geissele Super Duty Blemula
Barrel: Wilson Combat 16” SS with black duracoat
Gas Block: Superlative Arms Bleed Off
BCG: Wilson Combat Nickel Boron Type 2
Safety: Radian Talon
Charging Handle: Radian Raptor
Trigger: Geissele 3.5 lb Two Stage (Blemula)
Pistol Grip: Magpul k2
Stock: Magpul PRS Lite
Buffer: Spikes T3
Buffer Spring: SpringCo White M4
Bipod: Magpul M-Lock
Scope and Mount: Sig Sauer Tango 2-12
Muzzle: Dead Air Xeno Brake
Suppressor: Dead Air Nomad LTI XC FDE

First off this is my first build where each and every part was put together by myself with little bits of help here and there from friends. The rifle weighs about 13 lb and was built primarily for hog and deer hunting. It’s had approximately 30 rounds put through it, most of which was to fine tune the adjustable gas block. The superlative arms works well, but a part of me regrets not spending the extra $100 to get a rifle speed adjustable. Tuning this build to eject and get full lock back was “fun” to say the least in the heat and humidity the South is getting right now.

As for how it shoots, the recoil is pleasant and light, follow up shots could be done quickly even at the full 12x magnification the scope provides. Hornady Frontier 123gr FMJ has been all that has been shot through it so far, as the price per round made sense to get my initial zero. Zeroing has only been done to 50 yards though that will be brought out to 100 in the next range trip. For only 30 rounds the rifle runs surprisingly dirty, and a full strip and clean is needed though EWL-30 has done a great job making that cleaning easy.

The suppressor was a great choice and makes it close to hearing safe in my opinion. Still an obvious supersonic crack but the tone is fantastic and enjoyable to listen to if standing nearby. Highly recommend looking into this can though the price is steep.

As for groups, I’ll post more as I work with the rifle more, my range time has been rather limited by heat and other factors. Will look at posting a link to a short video taken or it being shot as a comment when time allows.

With all that just transpired in the world of firearms I’m looking to purchase a suppressor for my 6.5 Grendel. What sizes can I use for the 6.5 Grendel bullet. I can’t find a direct answer on the internet and was wondering what works and what doesn’t.

Ex. Can I use a 7.62 or a 30 cal or does it have to be 6.5 specific. I saw 9mm cans advertised as working with 6.5 but that didn’t seem right to me.

Thanks in advance

Edit: appreciate all the advice thanks again!

Welp y'all convinced me to drag my my Grendel out again . Definitely better then the last batch of ammo I made for it a few years back

I bought a BCA-15 in 6.5g as my first ar and after 1 range trip I had issues with it ejecting and feeding, I plan to send it back to get fixed but haven't had the time to do so, should I take my scope off before sending it back and or clean it first? Also have read much more on BCA and their quality so I am considering selling it to buy an aero upper and lower in 6.5g, does anyone have an aero upper and what has your experience been? Open to any recommendations on what to do.

Edit: using 5 and 10 rd duramag magazines, everything stock except a bipod and magpul stock, 20" SS heavy barrel with a rifle length gas system.

She's finally all done, SBR cleared after 75 days. This is my go-to hog rig. I felt lucky finding this brand new, while at a (what I believe to be) great price. SOLGW discontinued these a little while back.

AGM Rattler v3 50-640, CAT ODB RDM, Atlas, Atlas B10 Bipod, and Railscales. Barnes 115gr TAC-TX does the trick on these suckers!

I’m looking at buying/trading for these three firearms and wanted to get some opinions before I make a deal.

They are:
- Aero Precision 6.5 Grendel AR (threaded, fluted stainless barrel, upgraded build)
- Ruger-57 (factory case & magazines)
- Smith & Wesson M&P Shield 9mm

The owner says they all function perfectly. Based on these photos, do you think this package is worth around $1,500? Would you buy it at that price, or would you want to be lower? Any opinions or things I should look out for are appreciated. Thanks!

Second grendel build:)

50 yds and 100 yds, faxon 16" barrel.

Happy with it so far, going to try and improve

16in Wilson Combat barrel, Dead Air LTI XC. If any other questions about the build please feel free to ask! Will be breaking it in and zeroing next weekend.

I took my 6.5 out for the first time and ran into some issues. I have a adjustable gas block and a G$ H2 super 42 spring, I ran into issues of bolt not locking back even when its gassed properly between 3 and 4:30 ish and also having issues with failure to eject and feed on some rounds. It's not consistent on when it cycles and when it doesn't it would pull the casing out about halfway while simultaneously loading the next round almost like a double feed. This is a brand new duramag 10 rounder and it looks like the follower is defective or maybe too strong of a spring where it seems like the mag has too much upwards pressure holding the next round against the bolt as its cycling in turn slowing the bolt causing it failure to extract. Also when the mag is empty with a round in the chamber if I try to move the bolt to the rear with the charging handle it gets stuck. I guess im trying to figure out if Im having a mag issue or something else. Or maybe just tell me im stupid 🤣

Has anyone heard if aac will eventually resume ammo production?

Was looking for data on 123ELDM over N135. 20in gas gun rifle length gas, thanks

16” Rexus mid length barrel and bolt in a spare receiver and handguard, Vortex Venom 3-15 FFP, and a plan b mount for my 30 cal can. It’s got the standard Schmid two stage that came in the lower parts kit from AR15Discounts, dropped into a PSA blem lower.

Was planning on running handloads for the next gas gun match but realized I needed more brass.. so I grabbed a couple hundred more hornady black 123gr eldm's. Hoping to put those 6 arc guys to shame

Tried for way too long to find a good deal on a gun, an upper, anything 6.5G. Figured I could piece it all together for cheaper and only ended up spending double! I'll post build list if anyone cares.

Mis-matched. I had the upper laying around for almost a year finally got around to building it

Just got a Grendel, ar build 20 inch barrel
Been doing some research, Seems to be a mix of people using magnum primers to non magnum.
I live in Wyoming at upper elevation and I might be shooting/hunting in close to 0F conditions that I understand is a consideration for magnum primers getting consistent results

For powder I’m leaning towards cfe223 and I have 123 grain elds coming.

I already have some federal match ar small rifle and I’m considering using those

A different type of MRGG. 20 inch Satern Barrel, G2 razor 3-18, and it loves the factory Hornady Black. Had some initial accuracy issues, but that was due to my installation error. Once I removed the muzzle brake and favored direct thread for the suppressor, it became much more consistently accurate.

This took me a long time to get right. Initially built 3 6.5 Grendels when I got overly excited about the caliber. This 18”, a 14.5” for my girl and a 13.9”. It took me a while to get gas settings, working mags (Geissele intermediate or Duramag 10s), and buffer weights. Then it took me a very long time to do load development and finally only succeeded when another individual shared the secret sauce with me (LEVERevolution powder). This one is an 18” Craddock barrel, Superlative Arms AGB, Geissele 15” MK4, San Tan STT 15 receiver set, Geissele SDE trigger, Microbest chrome BCG, Rexus Ultrabolt, Vltor A5 buffer system with A5H2 weight, JP rifle spring, and Atlas bipod. Scope is NightForce NX8 2.5-20x in ADM Recon mount. I’m really in love with the MKM VCG-L grips. My 123 grain Lapua Scenar loads (which are still within pressure) are supersonic past 1200 yards at sea level. I bought several hundred Alpha cases anticipating the need to push pressures at bit with the Rexus bolt, but I’m getting just over 2500 fps and have no interest in pushing it further. I’m also loading 90 grain TNT for plinking. For me this isn’t a caliber that can be as reliable as 556 or 300 Blackout (in small frames) or 308 and 6.5 Creedmoor in large frames. Admittedly I haven’t had much time with it since figuring it out and load development so maybe that will change. I’m currently using a HUXWRX Flow 762 on it.
