First let me start off by saying that my last post was in no way meant to offend you. Secondly I would like to clarify that I would not nessasarily classify the ammunition that you have listed as "junk" but I also wouldn't recommend it. Military grade ammunition is usually set to a higher pressure which can effect cycling rates, and often times is manufactured by a lowest bidder contract which will use less than clean powders. On top of that "Failure to detonate milsurp ammo" is already a topic of discussion in the issues section. I say leave the mil spec ss109's in the mil spec rifles, yet even the our armed forces have choosen to ditch it in favor of a more suitable round. Currently all branches of the US Military purchase their match 5.56mm ammunition from Black Hills. You have stated that you are using cartridges loaded with 62gr. tungsten tipped penetrators which I have myself shot extensively to less than fovorable results. On the subject of the 55gr. Federals I can't say because i haven't shot them though their weight is a little low in my opinion for the 1x7 twist of the fs2k. And to answer your question, yes, my definition of "premium" ammunition is the "civilian stuff" made for woodchuck shooting... It's also identical to the rounds used to drop tangos at 500 meters, our military's Mk 262 mod 0 and mod 1(with and without cannelure). It was developed to offer increased accuracy, range and improved terminal performance over the standard 62-grain M855 load (which is like what you're using). Before you start hating your gun switch the ammo you're using to something else. You already have a lot of money into the purchase of it alone so why not enjoy it.
Bro, that's all ridiculious!
Yeah, the Black Hills ammo is sweet and it is used by the military in special applications (doesn't this make that milspec also -- it has an NSN, etc), but the VAST majority of rounds put down range by the US military and the remainder of NATO forces is SS109 spec (although XM193 still finds its way into training cycles). Quality MIL-SPEC ammo (none of the surplus I buy is junk from third world ****holes) is designed to go boom reliably and in EVERY other 5,56 I have, it does. Three ARs and a SIG 556 for the SS109; usually with no worse then like a 2% failure rate. Hell, I've taken the ammo that didn't detonate through the FS2000 (after multiple light primer strikes) and then loaded it in the Colt AR and it goes boom every time (except for that 2% failure rate that just comes natural to ammo). The XM193 (Swiss spec. or Federal production) I run through my HK93 because of the 1/12 barrel and I run it in my 7.5" AR because it seems to prefer it to the SS109 -- again -- ZERO issues with light primer strikes. Those 77 grn. Black Hills rounds are COMPLETE overkill for the majority of shooting that the majority of FS2000 owners will do.
The FS2000 is a civilianized version of the F2000, which is made to NATO specs to handle NATO spec ammo. The reason the firing pin change was implemented was because people were firing soft primered civilian ammo through a rifle that was designed to fire NATO spec ammo. You have the issue exactly backwards on this one, FN implemented the change because Johnny Knucklehead (not you -- Blackhills is good stuff) was firing what ever Bass Pro had in stock and the pin gun didn't like the soft primers (or the soft primers didn't like the heavy pin -- whichever), not because there was an issue with MIL-SPEC ammo. FN simply did not think it through. In attempting to protect Johnny Knucklehead they simply executed a poorly designed fix, which eliminated the ammo the rifle was designed to fire.
I'm not knocking you, clearly you are familiar with the ammo issues and I recognize I'm not talking to some ill-informed internet commando, but again, I think you are looking at this from the wrong perspective. There is nothing wrong with any of the ammo I use, the problem is with the firing pin system on the FS2000.
