LRRPF52, do you have any velocity data for lighter bullets in your 12.5"? I'm looking at a 12" Faxon barrel for huntting coyotes with 85-95gr bullets for more FPE (vs 5.56) out to 300-350 yards max. This would be for night thermal hunting where shots would normally be under 200 yards but distances are hard to judge. Thanks View Quote 2892fps average across 20rds. That translates to 2687fps for a 12" barrel. I also have a 12" Faxon barrel in my pistol. You can get an 85gr to go faster of course. A guy who shoots hogs almost every night has been getting much better than expected results with the Federal 90gr load. Tons of DRTs. |

2687 FPS is actually faster than I expected. That would very closely replicate the trajectory of my current coyote load from my 16" 5.56, but from a 12" barrel and still do it with considerably more energy. Thanks for the info, there isn't much out there on short barrels and light bullets. Now if I could just find a Faxon in stock at a decent price.

You get your can out of jail yet? I just got my 6.5 Ultra-5. On a 16" Grendel, it sounds about as loud as unsuppressed subsonic 22lr out of a 16" rifle; should be right about 140 dB.

View Quote Been in jail since September. I want a Maxim9 now too. Was hiking with my family yesterday up to some waterfalls. Apparently, it's been a big rattlesnake year. My oldest daughter (6) walked past something hissing at her, and said, "Daddy, a snake, look." I was thinking a little gopher snake, even though I've seen rattlers up in the mountains. Didn't freak out or anything until she kept saying it was hissing at her and making a noise. I came down the trail and saw the diamondback pattern on its back, with a tiny little rattler, and told her to get back. There was a group of moms above us with a ton of little boys freely roaming with sticks with very long leash supervision. My daughter, instead of going away, shut down and hand-railed the raised dirt on the side of the trail where the rattler was coiled at the base of a tree, mouth open and hissing. My little 2yr-old boy was just off to my right, next to me. I drew my 9mm and put 5 rounds into the snake. This all happened within seconds. Had a bit of ear ringing on top of what little hearing I have left. Came home and started looking at that deal on Maxim9s. Sucks we can't just cash and carry. |

Showoff!!! LRRP, you should be ashamed flaunting all these 6.5G toys...causing much lusting and economic chaos amongst the masses...LOL!
But seriously...Very nice. I've been fighting the draw of the 6.5G, but you make it quite hard. |

For that Ultra 5 did you go with .30 cal or 6.5? Looking forward to your impression on how it sounds, port pop and gas blowback, and impact shift.
If the Maxim 9 is too much of a one trick pony, I recommend the Omega 9k. On a Glock 43 its almost as short, plenty quiet, and versatile. |

Sucks that the 90gr TNT won't run without the can. If you open the gas port, it will probably run, but the gas will be a problem. It IS a screamer from a short barrel though. What's the expansion threshold for that? I couldn't find it on Speer's site.

View Quote As to expansion of the 90gr TNT, I don't know the floor on it but it is being used regularly (3-5 nights per week) to hunt hogs in TX, and is getting a lot of pass throughs and DRTs with impressive expansion and tissue cavitation from 6.5 Grendel, even on large boars. Running the numbers at sea level: 25yds 2605 fps 1356 ft-lbs 100yds 2375 fps 1127 ft-lbs 175yds 2156 fps 929 ft-lbs 200yds 2085 fps 869 ft-lbs It's only supersonic to 650yds at sea level, due to such a low BC of .281 G1. Fun hunting and practice round though due to low recoil. For my conditions on a day like today, the numbers are much different. 4500ft elevation, 91°F 100yds 2453 fps 1202 ft-lbs 200yds 2233 fps 996 ft-lbs 3" drop 300yds 2024 fps 819 ft-lbs 14" drop 400yds 1828 fps 667 ft-lbs 32" drop 2.3 mils / 1.2 mils drift Supersonic to 875yds, but only 255 ft-lbs left. Fun little 400-600yd bullet at the most for shooting distance. More appropriate for close range work, but a proven repeated killer on pigs. |

200 yards is plenty for most hunting in the South East. Never would have thought of the TNT as a hunting bullet. I was under the impression it's a varmint/ exploding bullet

I was under the impression it's a varmint/ exploding bullet View Quote In 6.5 Grendel, even from longer barrels, it has more controlled expansion. Same thing with the 85gr Sierra Varminter. There was a Grendel hunter that accidentally got a twofer on some does at around 300yds with the 85gr Sierra. The main advantage I see from a practical standpoint with the varmint bullets is lower recoil/better sight picture. Options include: 85gr Sierra HP 90gr TNT 95gr VMAX 100gr Sierra HP Of those, the 95gr VMAX has the best BC at .365 G1. From my 12", I'm not going to be launching them anywhere near .260 Remington speeds, so with hand loads, I'm expecting 2675-2775fps. There are also several other bullets in that weight class that are meant for controlled expansion medium game or target, including: 86gr GS Customs HV 95gr Lehigh Controlled Chaos 95gr GS Customs HV 103gr GS Customs HV 103gr G9 Ballstics Match 105gr Pure Precision My Lehigh 95gr CC load on CFE223 is very pleasant to shoot. |

Ahhh ok. That makes sense. Would be interesting to see what the TNT and CC rounds do in gel. I suspect that CC would really do a number on the insides of a deer.
Another interesting option would be the Barnes TSX 100gr? I'm sure the 120gr would work as well, but wouldn't have the speed to expand - at least that's what I think. ETA: Punched the data into a calc. Assuming a MV of 2400 for both 100 and 120gr TSX bullets... The 100 drops below the magic 1000 Energy level at 140 yards and the 120 gr only does so at 240 yards. IF (and it's a big IF) the expansion threshold is the same as many of the .223 rounds, assume 1700fps - the 120gr should expand all the way out to 370 yards. That's impressive. Please keep in mind - this is VERY new territory for me. My reloading and ballistics experience is limited to 9x19 and a very few .308 more than 2 decades ago with powders and bullets available only in Africa. |

We found that the 100gr TTSX and 120gr TSX expand down to 2000fps, limiting expansion envelope for hunters closer to sea level, but still within reasonable hunting ranges.
At altitudes where we commonly see even large game in season, the 120gr TSX has been used to take Elk at 407yds by Mark LaRue with a 20" Grendel in 2007. That's right at the edge of the expansion envelope at higher altitudes like 9,000ft and higher where we normally will encounter elk here in the Rockies and Uintahs. 90gr TNT is being used regularly to anchor hogs, including a recent 330lb boar. 330 lb Trophy Boar & 6 Hogs More |
|
Ok. 2000fps. That would really limit the distances at my altitude, but the tax bullets do hold together pretty good. I've had good success with 223 and 7mm tsx.
Wow that hog hunting video! Talk about the hammer if Thor! Out to 180+ yards! I'm guessing the TNT is where it's at in this caliber. |

There's a new 110gr Lehigh Controlled Chaos that expands down to 1500fps.
The Nosler 129gr ABLR expands down to 1300fps. |

Here are some size comparisons with 12" Suppressed vs 16" and 18" Grendels: http://i1085.photobucket.com/albums/j422/LRRPF52/20180808_195710_zpsm2saw5oy.jpg http://i1085.photobucket.com/albums/j422/LRRPF52/20180808_195807_zpswriuumda.jpg 18" 6.5 Grendel 2485fps 123gr SST 400yds 1800fps 885 ft-lbs 16" 6.5 Grendel 2440fps 123gr SST 375yds 1801fps 886 ft-lbs 12" 6.5 Grendel 2350fps 123gr SST 325yds 1803fps 888 ft-lbs I got 2384fps average with Federal 120gr OTM. I have not yet chronographed factory 123gr SST, but at 2300fps, it drops the expansion down to 300yds. At 2285fps mv, it drops you to 267yds expansion. What percentage of deer and hogs are taken within 200yds in the US? Even with that slower mv, you're looking at over 1200ft-lbs at 100yds, .460" expansion, and 80% weight retention in all of our tests. Another way of putting it is taking 275-325yds of performance off of a 24" .260 Rem or 6.5CM, when shooting 12" Grendel with 123gr SST. The .260 Rem and 6.5CM both have expansion with the exact same bullet out to 600yds. If you run the 24" 6.5CM ballistics, you hit the muzzle velocities of the 12" Grendel at 275-325yds at 59°F, sea level. View Quote And just got this in an email from PSA: Attached File |

man your rig is pretty freakin slick. that being said, i wish i woulda kind of took your advice on the optic for my 12'' grendel. i am so let down in the PA 1-8 with griffin reticle. it makes my strike eagle look like comparing a 1-4 tasco scope to a vortex viper. currently working with PA to swap it out for something else.

I like the ATACR a lot.
For me, the 34mm tube and weight seemed a bit much for a lightweight build, but it's a great scope for a larger AR too. The March is 30mm tube, 17 ounces, really short at 8.4" long. |

I was really set on the vortex viper genII 2-10 but then decided the Griffin reticle would be sweet. So i got the PA optic. Total let down, although i may have a lemon and its on its way to be exchanged. The quality of glass was worse than the 4 power tasco i bought for 5 bucks at a yard sale. So needless to say im scope shopping

It was torture due to a FTF after each round, but I ran 20 rounds of Hornady ELD Match through the 12" 6.5 G PSA upper and came in at 2225 fps +-. I will get the FTF sorted out and come back with more data after more rounds.

I am sure that is part of it, but I need to look at the buffer and trigger also. I was also breaking in a radian 8.7" .300blk and that didn't FTF, but the trigger would not do a full reset. After each round I would tap the trigger forward with the top of my index finger and the trigger would click into place. I dropped in an MBT-2s but I had walking and easy slide out if the gun was charged. I bent the trigger springs slightly to seat them on the pin as they were missing. So that is probably part of the problem as well running the Spikes T3 buffer in this lower. I cleaned/lubed everything and will replace buffer and put more rounds down the pipe before touching the trigger. I used the ASC 10 round mags and loaded those immediately upon receipt, but that could also be an issue. I can get 10 rounds in one, but the other is definitely only going to take nine right now.

I’m not LR but I’ll chime in with my observations. Some of the more temperature stable powders for 85-107 grain 6.5/264 bullets in 6.5 Grendel is Benchmark and IMR8208XBR. I’ve had good results from H-335 and Accurate 2230/Xterminator.
