Ammo sticking problems

[Melglass]

My barrel is not even on a receiver yet just got it in Friday. Reading up trying to learn all I can on the Grendel forum.

[Melglass]

Yeah, that's what I was thinking. All the smart fellas are over on the 6.8 and 300BO forums.

I know you are being sarcastic but I shoot 6.8 and 300BO along with 7.62x39. I’m not stuck on one caliber I shoot them all. The 300 is way overhyped but is fun to shoot suppressed with subs and works pretty good for the kids. Will probably get a Howa Grendel for the kids to replace the Blackout for hunting. The 6.8 is a good killer and so is the 7.62 in its range.

The only AR I've ran that stuck rounds had a FN barrel chambered in 5.56 NATO shooting milsurp M855 rounds, after a good cleaning it hasn't stuck a single round since. The Grendel hasn't given me any trouble.. maybe I'm just lucky, but I'm guessing people having issues are more likely to post on a forum than someone who isn't.

Mel you still haven't answered that most basic of questions... which barrel DID you buy?
Busting in out of nowhere, complaining, but not offering relevant info leads one to think maybe a troll has landed. Dispel that feeling with some info and then maybe someone can help.
As stated earlier there are lots of Grendel makers now and their QC is definitely suffering. That being said there are 1000 ways to feel a barrel is sticky... starting from the most basic of "did you clean the chamber and barrel from any packing grease?"
True, some barrels -- and other parts -- can and will show up defective but I can say the same thing about Chevy's, Ford's, Wrangler jeans etc etc...

Grayfox, This post does seem a more then a lil suspect doesn't it.

Melglass,

Grendel owners with perfectly functioning barrels have little to post about.

[Melglass]

Not a troll just trying to understand why there seems to be so many problems with this one chamber. I have a genuine interest in this caliber that was kicked off lately. As far as barrels I had ordered an AA 16in a while back but they changed from coated to non so I canceled my order and ended up getting a Satern but got on a 7.62x39 kick and ended up not putting it together and it got traded off. My interest got perked again lately so I looked around to see what was out there and almost got a Faxon after watching Johnny’s reloading videos and I have had luck with them before. Ended up ordering a ARP because they have been good with me in the past too. If people are thinking I am here to cause problems with this post please lock it. It is just me trying to gain knowledge. The reason I did not list what barrel I have is because I have not mounted it so don’t know if it is a problem yet.

If you got an ARP you should not have any problems. Having read through his site in the past, it is apparent that he can do no wrong. I'm surprised that JP only stole his bolt design and not more.

[Melglass]

I have had luck with his barrels, Faxon, CLE and White oak and I am sure I’m forgetting someone as far as AR barrels go. My bud got a BCA 7.62 upper because that was all he could afford and it has run 100% with solo accuracy but plenty good enough to kill hogs. Yes I could see the sarcasm running out of the last post.

[StoneHendge]

Hey, more power to him. Seems to have quite the following. He managed to sell out a run of 6.5 twist 224 Valkyrie barrels that "work best with 55-77 grain bullets". That's spinning a thin jacketed 55 gr Nosler Ballistic Tip are around 375k rpms. I think 400k is where I've read of jackets getting thrown off within 10 yds of the muzzle.

Shot plenty of 50-55s out of my 6.5 twist PAC-Nors back in the day at 3300 or so. Never had one go MIA even as the round count got up there. Still have one on my blaster upper and shoot nothing but fmj and 50gr Hornady sp out of it. It still shoots knots.

The first Arp 6.5 (which was an "LBC" style not Saami, he's a bit of a newcomer to the Saami side of this caliber) I bought from him had a lot of sticking and feeding and ejecting problems... turns out to have been mostly due to parts in his proprietary bolt design, and it all smoothed out after about 100 or so rounds. From my experiences he is more or less run-of-the-mill, no more, and hey, more power to him if he can sell his wares, this is America after all.

The biggest issue with Arp products is any proprietary parts, after all he's probably getting ready to retire like many older guys (of which I am one, but already retired), so you worry whether those prop. pieces will be available for replacement purchases if and when the originals fail... just something to keep in mind when you go those routes.

But I would not expect much more than simply average out of his shop. If you have a few from him that are good, then this one is that average-maker for you... get in contact with him -- he usually answers his emails so maybe he has some ideas on what you're facing with his barrel.

If you feel burned by the purchase it could be the mfr not the caliber. Ammo makers don't make lots of ammo for calibers that don't work, and the Grendel works very well.

Been following the 224 issues. It is on my list of things to do. Sitting on enough projectiles to burn out a few barrels. Looks Ike he is saying that he is not happy with how the throat was cut so that is the bullets that will probably do best out of the mag. Seems to be a few guys that are having great luck with handloads been following some post on The Firing Line. Like I said I like to play with a lot of different calibers. Lol

Have a few of his barrels and all have been great. I did get the HD750 bolt but if I have problems i can use any .136 bolt no problem. His barrels have shot well above the price I have payed for them in the past so no fear of that for me. Not saying they will shoot with my cut rifled barrels but darn close. I don’t put a lot of time in load work up now like I did in the past. I normally just shoot some groups till I find something under an inch then stick my thermal on it. Hell my 7.62 will do it with wolf and shoot knots with the steel case SST load. Killed 26 hogs this year with Tula 8M3, a few with Wolf sp and a few with the SST. Have built guns in 7.62x39 with ARP, KaK, ARD and a 7.5 inch that I can’t remember. All but the 7.5 shot the SST under an inch but some shot the other low dollar ammo very good too.

Yeah I just find it funny that he viewed himself as the savior when he was the first to do a 1:6.5 twist Valk after Sierra decided that the 90s required a 1:6.5. And then it didn't work.
