Excellent choice, more than highly recommended :-)
It is not a "heavy" rifle, in fact, the JP rifles are among the lightest AR's out there.
Yes, there are other solid AR's out there but JP is among the best in reliability, fit and function.

I have put in over 500 J.P.'s and they are the best and I have tried others. J.P. supports out sport a lot.
A JP trigger system installed and tweaked by Benny is the best of all AR triggers IMHO. Benny does the JP trigger like no one else, not even JP. My first JP trigger was installed by JP and it was sweet. My second I did myself by following the instruction video and it was the second best trigger on an AR I have ever had. Finally I had Benny rebuild my original JP installed trigger after about 12000 miles on it and it is so sweet it can't even be described. Almost no take-up, breaks like glass and not much more over-travel than take-up. Sub 2 lb and solid as a rock for quite a few more thousand rounds since :-)

My brother just moved out to the Silicon Valley area and I was hoping to use this match as an excuse to see his place lol. The problem is that it seems to have filled up very fast. I tried to e-mail the person on the gun club's website to inquire about availability but the e-mail listed on the sight was not a valid address. Is there any way I can get a spot in this match? Please let me know as soon as possible, as I have to order plane tickets in advance. Any help would be much appreciated. Thanks for all your help!
Sorry about the email link at the HotShots website not working, it has been fixed.
The 2012 BARC has been sold out since December 12. Waiting list has 15+ folks on it. I doubt that everyone on the wait list will get slots this year. This match has been selling out pretty quick for a few years now, you need to act fast when registration opens up.
Use the (fixed) email link at the Richmond HotShots website to get me your contact information and I will put you on the email notification list for future matches.

I cannot recommend the full install type trigger kit from JP Rifles enough. IMHO it is a way better choice than any modular type trigger out there. Anytime you use the entire receiver to stabilize the trigger pins instead of relying on an internally boxed trigger group you will get a better result at the trigger itself
For about the same price as an AR Gold system you can send your lower to JP and have them do a full trigger install and setup for you. The kit can also be DIY's if you have any decent gun work skills at all, the video instruction disc that comes with the JP kit is first rate.

I have never seen rounds that fit mag length in an AR jam the bullet into the lands. Mag length OAL is way to short for this to happen (2.265" is typical max mag length).
Do you have an ammo check gauge? If so, try drop testing your ammo in it, If it fits and drops free from the gauge it should be good to go in any standard chamber.
Check length of unloaded brass to make sure it is under 1.760" (trim to length is 1.750").
The suggestion about bullet seating causing the case neck to deform is possible.
Crimping is not required in my humble opinion and you should only be using a taper crimp die IF you are crimping at all. A roll crimp type die will cause this. Also, lot's of seating dies are designed to roll crimp as they seat if the die body is threaded in deep enough. Maybe you have the seat die threaded in too far and the seating stem threaded out too far so the die is crushing case mouth on you.
Hope this helps.

Try doing an Apple Software Update pass and see if there are Java updates available, that may fix things for you.
Also, try downloading and installing Mozilla FireFox. Make sure to not let it make itself the default browser on it's first startup (unless you want it to be the default browser). If it runs same as Safari and Chrome then the issue is not your Mac or the browsers.
Some ISP's don't provide very fast upload bandwidth which will make websites appear to be slow because it is taking a long time for your request to get to them.

I highly recommend the Dillon spray lube for rifle cases. For general 55gr blasting ammo I don't bother cleaning it off till after the rounds are fully loaded then I give them a 15-30 minute tumble so the rounds are dry and clean. You don't need to use very much of the Dillon lube so there won't be any big mess to deal with.
I put 100-150 cases at a time in a cardboard box top and spray them lightly then shake the box around to get the lube distributed, then they get fed into the press right away.
-
What about the redding competition die, anyone using it?
Yes, excellent choice. It's the seating die I use with 69gr and 77gr Sierra Match Kings. I use the standard Dillon seating die for 55gr ammo.
IMHO the windowed seating dies aren't really helping you anywhere.
I use the standard Dillon sizing and taper crimp dies and think they are best choice for .223
Does it leave a slight crimp in the ogive of the bullet? My Dillon seating die does. I am looking at buy the micro adjust for 223 because I switch back and forth between bullets
That is the biggest reason I use the Redding die. The Dillon and RCBS seater dies left an indent ring on 69 and 77gr Match Kings, the Redding does not.

With jacketed bullets, I never cleaned anything but the chamber on any of my competition pistols.
be
I'm with BE, when I first started shooting I would clean pistol barrels after every session, then I wised up and started doing it this way too.
Rifle barrels do get some brushing. Cannot remember the last time I cleaned a shotgun barrel though

If you want to force mag changes have a standards stage. (Gasp!!!)
Given that 30 plus round magazines are easily and readily available, I'm mildly against any sort of cap on mag limit in Tac or Tac Limited/1X/Iron Sight/Limited division. Stage design will easily nullify any advantage that high cap mags have anyway.
Making 20 rounds the limit to prevent monopodding will simply make me build up the bottom of the 20 rd magazines.
Ayup, just add a "Presidente" type standard stage with mandated flat-footed reload if you want to test reload skills. Mandating a reload on a field course just doesn't work for me, nor does mag capacity or size limits.
-
30's kept fully loaded at all times. 3 on my belt and one in pocket to load up with during make ready. I bring about 8 30's to matches and load them all up in the morning then reload ones that were used as required
2 empty GI 20's in my bag just in case.
The only time I have ever really needed GI 20 was a sloped ramp where a 30 was too high. I also use a 20 is for a starting mag if there is a mandatory standing reload like a Presidente type drill, the 20's fly outa' the magwell :-)
I never use 20's prone as they are too low for mono-podding. Low ports, I just cant the rifle on a 30 while mono-podding.

If you are still subscribed to this thread you belong on M4carbine or ARFCOM general discussion threads not on this forum, thus Is entry level stuff guys come on.
Ayup, eggs-ackerly why I am not speaking to the video in question here as there is nothing to question or answer there

.223 and 5.56 cases are identical in external dimensions. The chambers themselves are also almost identical. It is the barrel leade/throat area where the difference lies. 5.56 has a much longer jump to the lands so longer tracer rounds the military uses will not cause overpressure by getting jammed into the lands when chambered.
The following article pretty much sums up most of the facts here. It also says the same thing about the Mini-14 chamber being safe for 5.56 ammo as gunfixer notes in his post.
http://www.cheaperth...spx?mediaid=316
BTW, IMHO, if a specific 5.56 ammo has the exact same bullet ogive profile and OAL as SAAMI spec .223 ammo then it is going to run safely in a .223 chamber even if it is a hotter loading than SAAMI spec as the 5.56 brass is stronger and will keep things under control as long as the bullet is NOT jammed into the lands when chambered and has some freebore available. The danger lies in using 5.56 ammo where the bullet profile contacts the lands in a .223 chamber. You need to measure things to see if it is safe to do so. A .223 REM barrel is not a weaker barrel than a 5.56 NATO barrel. They all start life as the same barrel blanks then get chambers reamed to either .223 REM, .223 Wylde or 5.56 NATO. In other words, 5.56 NATO and .223 REM barrels are of equal material strength and neither has a higher propensity to blow up on you

Geoff, this got me to thinking about your prone method of monopoding off the magazine AND pushing down and back on the FF rail. I wonder if that gives any flex to the system. I'll have to test it at 200 and see what comes out. For long range stages you're almost always braced diffrent: Prone, sitting, rooftop, through a window.... I'll have to test myself with my rifle to see if I get any shift with the diffrent positions and pressures on my rifle.
Not that I have found with either of my competition rifles with FF HG's. I have done group shooting and zeroing at 200 yards with bipod using neutral hold force and mono-podded with lots' torque on the rifle. Both result in pretty much the same POI and yield similar group sizes. Probably be able to see some diff at 350+ but I have not tested this beyond 200. The real trick here IMHO is to do whatever you do to the rifle consistently
BTW, I don't pull back on the HG with weak hand when I mono-pod, just down force like I am trying the bend the rifle in half over the mag. I push the hand guard away and try to "stretch" the rifle when I shoot offhand. I only pull back using the pistol grip to lock the butt-stock into my shoulder pocket (I do this in all positions)

Think about it for a second. With an A2, regardless if you have a free floated barrel or a standard A2 setup, for the A2 irons, the sighting system you're using is a front sight attached directly to the barrel. No matter which way you torque or flex the barrel, the sight is going to go with it.
Not so, I know for a fact that at 200 yards the sling tension when shooting prone versus a neutral offhand hold is worth 4 clicks of elevation and 2 clicks of windage to get the same POI. This is using a Colt A2 HBAR 20" with non-FF HG. My free-float HG irons AR exhibits no detectable POI change at 200 yards with high sling tension on HG versus neutral hold.

there ya have it, I'll stop over-thinking it and pop the two 2016s in there an see how it looks on the dim indoor range during practice. thanks!
The biggest reason I went this way was not to brighten the dot in low light, but to make the dot work really well while facing the sun. Almost as good as a C-more on mid-range setting with 2x 2016's
BTW, dot size is important too. I have one on each of my open competition guns (rifle, pistol & shotgun) and found out through trial and error testing that the 8 MOA dot was needed for pistol and shotgun. The 4 MOA dot only works well on rifle for me. On shotgun and pistol the 4 MOA dot was always too small for me and harder to pick up quickly on the draw or mount.

Been running 2x 2016 batteries in a slide mounted optima on an open gun for years now with no tape, no soldering, no electrical worries whatsoever. As Nike says, "just do it".
The only thing I have had to do is put a small amount of blue loctite on the screws every time I change batteries or slide slamming loosens them up.

I agree with adding the muzzle brake now to the barrel you have as it is the one thing you can do that will make a very noticeable difference in performance. You will be able to drill repeat shots in a whole lot faster with a brake and that means getting your points faster than ever :-)
Learn to shoot with the heavier barrel to start, the extra weight will help damp some of the cycling impulse the heavy stock bolt carrier imparts to the rifle (you will be able to notice this once you have a muzzle brake). When you move to a lightened barrel later then you can add a lightened carrier/buffer combo and adjustable gas block to optimize things there and further stabilize the rifle during recoil.
The only other things really needed to start getting competitive with your AR are a good trigger which you said you have and lots of ammo to practice using that trigger with

outerlimits is right, just trim the tongue on the Remmy ones, they are the same otherwise. I have some for Remmies and some for Bennies and both types work fine in the Remmy
-
Secondary red dot on my open rife is zeroed at 50 meters so it and main sight agree at all distances past 1st crossing. Who wants to keep a lot of different offset data in their head anyway
Dot is as low as possible on hand guard to get minimal barrel to dot offset (about 1.4" on my setup). This provides negligible POA to POI offset on close range stuff. No need to hold over the top of targets to get upper A's this way :-)
-
Use your pistol to get to your shotgun. Use your shotgun to get to your rifle.
+1 on that. Best use for a pistol IMHO is to fight your way back to a rifle
