You can get about 125-140 per pound of RL15 out o the 308s. You should easily have another 300 rounds of 308 out of that 2.5 lbs. What projectile are you loading for the .308? I can save you alot of time, and just give you a powder charge that borders on pure awesome.

I'm starting to wonder why they DON'T specify it, brother...

Disregard - found it. You need an Armalite AR-10 rifle length gas tube, before we go further.

Gas tube is too short, first off. Right away. What's the gas system length on this rifle/carbine? You'll need to switch to an Armalite gas tube, for certain, to solve that issue, as issue #1.

Read this article, man - tell me what going on, based on this article... http://www.defensereview.com/m4m4a1-carbine-reliability-issues-part-ii-diagnosing-the-root-cause/

Needs to be pinned topic.

For option 1, just weigh the brass, and sort loads by weight. External dimensions are the same, so heavier weighted brass has less internal volume. Report back with brass case weights, lowest and highest, and I'll give you a great recommendation on the amount of RL-15 you need for those Hornady 75s. That's my go-to shiit, right there. You could even weigh 10 at a time, and average - it's not going to matter that much, brother. EDIT - You'll only need about 2.5 lbs of that powder to load all 600... Get another 600 ready to go...

No worries - already replied to your other thread - we'll run it where ever it shows up.

This might all be the mag catch, too. Bolt over base usually means the mag spring is too strong, and is shoving rounds up, on top of the bolt, before it can go into battery... They're a fucker to clear.

What other mags have you tried?... 2 x 25rd PMags is what I'm seeing. What Spike's gas tube? Details on it, though it's not the issue. Exact dimensions will help. Length. Take a pic and post it, of the gas tube in the upper receiver. Remove BCG, just a pic of how far the gas tube sits into the upper...

Not to downplay it, but it's just a job, brother, seriously. Just like any other job. Sometimes the job is great, and sometimes it absolutely sucks a$s. I was lucky enough to be where I was, when I was, with the people I was with, at the direct right time. Repeatedly. That's like gambling, and winning. That ranged a 10 year span of my life. When the job absolutely sucks a$s is when you really, really appreciate the people that are going through that suck with you, just like you are. Sharing that big bite of the shiit sandwich, and smiling as you choke it down... You realize how strong they really are, collectively, and how strong they make you. It's the sum of the parts...

Throw it down right here, man - thread is already going.

Unpossible. Not the way I'm gonna run your ass around, penis growing outta your foot or not. Even once a year on this poop will keep you WELL below the Big 6, brother...

I cannot imagine giving someone my toolboxes... filled... with specialized shiit... I couldn't do it. I'd have to club a motherfucker like a baby seal before they could take a Matco #2 screwdriver...

Zamboanga, Isabella, Jolo, Tawitawi... That's the last you go southwest from the "mainland," then you're in Indonesia. That shiit was under control during Bush. I'm just sayin'.

Yep. 100% and then some.

This is personal to me. That area is a shiithole, and I was on the deployment that Jay Blessing was killed by an IED on. He was the 2/75 Bn Armorer; Gary Toombs was the "contract civilian armorer" to the Bn, in the same HMMWV with JB when the IED went. CSM Toombs was a Company Sergeant Major in 2/1 SFG(A) when I was there the first time, and moved over to Ranger Bn as the civilian armorer after retirement from the Army. Bad MoFo. Much respect for him. He survived the IED that day, but it took the driver's compartment right out of the vehicle.

It's not a problem in the Philippines - was there from Jan 2002 through August 2002. We "assisted" the AFP in reducing the Abu Sayyaf Group from 1,000 members to 100 members during that timeframe. The caliber smoked 'em.

Solid parts list, except for that part ^^^. Personally, I'd run Armalite AR-10 Carbine parts in place of that. And I do.

Here's the info for my second reference above - a requirement for a new 7.62 rifle at the squad level. http://www.military.com/daily-news/2017/04/27/us-army-search-new-762mm-rifle.html Ironically, IMHO, these are "Afghanistan-Problems." These guys are looking at changing an Army-wide inventory level item because of a theater-specific problem. That's METT-T, not a weapons-platform issue...

Here's the info for my first reference above - you have two Generals that don't know WTF they're talking about, testifying about it. First, they talk about how underpowered the 5.56 is, but they turn around and say SEALs use the H&K 416, to it would be the perfect weapon to field... Duh... 5.56... Then, they're talking about this - which we've all seen firsthand - is NOT true... “All the things that we could do to marginally improve it aren’t going to make a big difference, because the operating system is literally dependent on a puff of gas that blows a floating bolt back and slides it back into position,” Scales said. “And any amount of dust, in my case, dirt in our soldiers’ rifles — fouling from the round — will cause the weapon to jam.” Read it all here: https://kitup.military.com/2017/05/m4-carbine.html

They're working on that. I bolded two paragraphs below - the first one addresses Sisco's original post - there's alot missing from that article, and the information coming from two Generals is quite contradictory - they both agree with each other, but they both contradict the information on 5.56 power, and make themselves look like fools. The second paragraph address the new "need" for a new SDM rifle in 7.62... http://www.military.com/daily-news/2017/05/25/army-chief-calls-for-762mm-round-for-m4-rifle.html Military.com | 25 May 2017 | by Matthew Cox The U.S. Army's chief of staff revealed Thursday the M4 Carbine's 5.56mm round can't penetrate modern enemy body armor plates and plans to arm infantry units with rifles chambered for a more potent 7.62mm cartridge. Responding to questions from Senate Armed Services Committee members, Gen. Mark Milley conceded that the service's current M855A1 Enhanced Performance Round will not defeat enemy body armor plates similar to the U.S. military-issue rifle plates such as the Enhanced Small Arms Protective Insert, or ESAPI. "The 5.56mm round, we recognize that there is a type of body armor out there, that it doesn't penetrate. We also have that body armor ourselves," he testified. Milley told lawmakers Army officials at the Maneuver Center of Excellence at Fort Benning, Georgia, have developed a new 7.62mm round to solve the problem. "We have developed a pretty effective round down at Fort Benning," he said. "We know we have a bullet that can penetrate these new plates." Sen. Angus King, I-Maine, asked if the new bullet will require a new rifle. Milley said, "It might but probably not," adding that weapons can be chambered for various calibers. However, the M4 would require a new barrel, bolt carrier group, buffer system in addition to a new lower receiver to shoot 7.62mm ammo, experts maintain. He later told Sen. Joni Ernst, R-Iowa, there are systems on the shelf today that, with some very minor modifications, could be adapted to meet the Army's needs. "I think there are weapons out there that we can get in the right caliber that can enhance the capability of the infantry soldier," Milley said. He also told lawmakers that not every soldier will need a 7.62mm rifle. "This idea that the entire Army needs the same thing all the time, it's not necessarily true," Milley said. "There are some infantry units that are much more highly likely to rapidly deploy than others and conduct close-quarters combat that we would probably want to field them with a better-grade weapon that can penetrate this body armor that we are talking about." The subject of the 5.56mm round being underpowered came up at a May 17 hearing before the Senate Armed Services Committee's Airland Subcommittee. Retired Lt. Gen. John Bednarek and retired Maj. Gen. Robert Scales Jr. testified at the hearing about the U.S. military's future small-arms requirements. Ernst said that Scales testified about "a weapon that could fill the role of the light machine gun and the rifle." "Is the need for a machine gun a higher priority than just a basic rifle?" she asked. Milley said that infantry units need both to be effective. "I think what [Scales] is talking about is the Marines are adopting ... the M27" infantry automatic rifle, a version of the 416 made by Heckler & Koch. "We are taking a hard look at that and are probably going to go in that direction as well, but we haven't made a final decision on it," Milley said. "The infantry squads and infantry platoons -- they've got to have an automatic weapon for suppression; they've got to have the individual weapon as well, so you need both ... to be effective in ground combat." Sen. Jack Reed, D-Rhode Island, asked if the new 7.62mm round would still be considered a standardized NATO round that could be used by allied countries. "It's a 7.62mm round, so I think the answer is yes," Milley said, promising to get a more detailed answer. This is not the Army's first effort this year to equip infantry squads with 7.62mm rifles. A recent directed requirement from Vice Chief of Staff Gen. Daniel Allyn prompted Army weapons officials to write a new requirement, and most likely they will conduct a competition that will result in the service equipping each combat arms squad with a new 7.62mm squad designated marksman rifle, said Matt Walker, deputy for the Lethality Branch at the Maneuver Center for Excellence at Fort Benning, Georgia.
