Title: Price of .223 Ammo
Post by: nelson96 on February 23, 2015, 06:44:17 PM
Similar to the .22lr thread, I thought we could let others know when there is a sale on .223 ammo.

At my local Cabela's.....  Starting Thursday (2/26) they are offering 300 rounds of PMC 55gr FMJ in a dry-storage box (plastic) at a price of $99.99 with no said limits.  This is a pretty good price considering is has been a couple of years since I have been able to find it under $7/box, locally and without shipping charges.

Bi-mart today had American Eagle for 6.99 box.

My find is a little better ($6.67 equals a $16 savings on a thousand rounds), but that's nothing to snear at.  Did they have a limit?  Two years ago I was buying the cheap Federal for $5.99/box and if I purchased a thousand rounds I got a free 50mm ammo can.

I can on rare days find 5.56 Federal on sale at my local Fleet Farm for $5.99-6.99. That said, I could practically throw a rock and hit the ATK production building in Anoka (city just north of me). It seems like Federal passes the shipping savings on (just a guess) because Winchester white never goes below $7.99-8.99. You'd think the shipping savings would be better for sending hunks of lead around the country. Or maybe Fleet Farm handles local shipping?

The Federal retirees lament the days when they'd let employees take as much as they could shoot home.

If you have a local ammo producer, it might be a way to save. Just a thought.

No local producer here.  I don't really even need the ammo right now, but am all about stocking up when prices hit a certain point.  I'm not going to be like my father and tell stories to my children and grandchildren that start out like "before you were born I could have bought X for X and now I can't afford to buy it".

SA,TX area:

Just bought Monarch (Serbian) 55gn .223 for about $5.50 (20rd box, steel) a couple of days ago at Academy.  Tulammo is priced about $.50 cheaper a box at Wally World, but it's rarely in stock.  The next cheapest is around $7 for AE.

The Monarch isn't awesome, but I'm all in about 4" at 40m offhand through a 1/8" bbl.

The dry boxes are junk, for use with ammo, but handy for other things.
The add didn't list a limit.
I didn't notice earlier that the sale didn't start until Thursday.
Went down yesterday evening and they turned me away.  >:(

Obama is giving up on banning our guns and is now going after ammo, since ammo is not protected under our constitution.  Even though the ammo he is currently going after is "mil-spec green tip", that doesn't mean he won't go after others if he is successful with this one.  Even if this plan doesn't work for him, I predict that it will start another frenzy causing shortage, that will start before the last one ends.  And because ALL .223/5.56 ammo will be targeted by low information buyers, ANY .223/5.56 ammo will be the first that is hard to find.

http://www.washingtonexaminer.com/article/2560750

For that reason, I went to Cabela's today and bought 1800 rounds of the ammo I mentioned in my OP.  If you're interested in some, you better hurry, it was going fast.

When I got home, I was able to fit 78 boxes (1560 rounds) of ammo in to one dry-storage box, which are better quality than I anticipated.  I'll use the other five, now empty, storage boxes for something else.

When I'm either in OR or anywhere near the Columbia River, I make a point to head to the nearest Bi-Mart on the Oregon side and get whatever I can't get at home.
Avoiding sales tax is worth almost 10% to me.

The majority of my .223 is bulk hand loading.  I buy the $10.99 bag of 55gr hornady soft tips (shooting steel is more interesting than paper IMHO).
(Here's the FMJ link if interested: http://www.natchezss.com/product.cfm?contentID=productDetail&prodID=HO2267BAG&src=tpCtg (http://www.natchezss.com/product.cfm?contentID=productDetail&prodID=HO2267BAG&src=tpCtg))
.223 isn't the easiest or most fun cartridge to reload, but until I can buy retail @ $0.22/round it's cheaper if I'm willing to do it.

I've also recently got into the steel cased Tula .223, as that's available locally $4.99/20rnds before tax.
It's a little rougher on the gun, but the replacement cost for my barrel is < $200.  It functions ok, but I'm convinced it is loaded hotter or something about it hits high at 50 yards.

My problem is that I'm not willing to reload it for the reasons you mentioned.  8)
$203.94 is what I would have saved on my recent purchase (1800 rounds), using your $0.22/round cost to reload, how long would that take you to load that many?

Pricing may dictate a change very soon.

Pricing may dictate a change very soon.

Brass prep is the most time consuming step.  I got some nifty tools as Christmas gifts that help with neck trimming.
What I do when I am bored, or want to escape my house of screaming children, is retreat to the garage and do things in batches.

When I have fired range brass, I dump into the tumbler.  I do this to clean off debris and protect my dies more than to make it pretty.  I let it run 30 minutes while I do something else.
Then I spray with case lube in batches of 50.
Next I full length size and deprime.  I haven't timed this, but how quickly can I set a case into the shell holder and pull the press arm?
OPTIONAL (do this for first time fired military brass) neck trim, and swage primer pockets
When I've accumulated 100 or the desired quantity in this state I stop.

I use an RCBS hand primer, which works fantastic sitting on the couch.  This allows me to tolerate TV my wife insists on watching.
I prefer a hand primer for 5.56 since I can FEEL if a primer pocket is tight and requires reaming.  I just set aside any stubborn cases.

At this point I probably have a couple hundred cases all ready for charging and seating.  I sent maybe an hour resizing 200 if you count all the above steps.
Then another hour priming - but that was time I would have wasted on the couch any how.

Another benefit of this process, is I can then wait to loadfor the occasion.  Maybe I want soft points for steel.  Maybe a distant cousin invites me to go varmiting.  While I have my pet loads, I have a variety of bullets and powders.  No reason to commit hundreds to a certain load recipe before you know what the circumstances are.

I do all this with a single stage - and frankly given the additional brass prep needed for NATO cases, a progressive wouldn't work well with varied neck lengths and primer pocket thicknesses.

So what you are saying is that 1800 rounds would require a shit load of time that could be better spent doing more important ammo where reloads are easier to do and the time/cost/benefit makes more sense?  ;)

Yes. Except for my typo. $325, not $320.  So $341.93 with shipping. I just checked my order again.  I also accidentally hit the reorder button and a message popped up that they are being swamped with orders right now and to expect delays in shipping.  I wonder why...????

What's a good number in your guys mind to have on the shelf of .556? I'm not in panic mode. I'm slow and steady at building up stock for now. I like the 420 round cans of M855 when they go on sale at Bi-Mart for $169. I also read an article today that the NRA is getting backup from the politicians in D.C. so that is some good news.

Perhaps, but I fear the day may come that having my .223 reloading squared away is the difference maker.

As info, in half the time I can cast the lead bullets AND reload as many .38spl - and they cost half the price of .223 components.

I really want a lever gun in .357mag...

I'm guessing you're talking about the BLR?  My wife has one of those too (I won it in an Elk Banquet raffle and gave it to her).  Browning doesn't offer that in .357 anymore, not sure they ever did.  The BLR is a fine rifle.

Thanks for the offer.  I will keep that in mind.

Usually a good source for free brass is to visit my range soon after LEO teams train.  Especially when its wet out, the cops rarely pickup their brass.  Usually this happens during the week so I have to plan ahead and get a bit lucky at the same time.

Yes the panic has started. You could peruse the many ammo sites and watch the price rise. Bulk ammo had 885 for over 600 per thousand......and the xm193 went from $479 which is high up to 515 in the last few hours.

This ammo type was generally going for 330-360 per 1000.

You can call it supply and demand if you want.......I remember who's price inflates that fast.

If everyone would just relax and stop fear buying this wouldn't happen.

Take the link above again.   $490 now for the same stuff!    And that is without shipping.   I'd say close to $.12-15/round more than 10 days ago.   

Also, a little grievance I will tuck in here.....I went to a Field and Stream store today too.   I got a new trout reel, and my buddy bought a kayak.   I went over to the ammo section just to see what they had.   Nothing bulk, just 20 to 100 rnd boxes.    The clerk/sales guy there sort of went off on me when I asked if they had anything in bulk....."You know the government isn't banning all .223, blah blah blah"   He immediately started jumping on my back after I asked about bulk cases.   I didn't mention anything about bans or the government, or anything like that.    He just assumed I was going to horde.   I politely explained to him I was up on the current events, and I wasn't going to spend a lot per round and it wasn't worth it to me to buy boxes of 20.   It isn't worth it for me to spend .50+ cents a round either.    Just like 22LR, I got a maximum price in my head.   I'm not going over that, unless it never comes back down.   I'm sure it will.

Post by: nelson96 on February 28, 2015, 04:58:34 PM
I suppose you could call me "part of the problem", but I have no problem with hoarding.  I only added to my stash with my recent purchase (1800 rounds) because I figured the latest news would strike a run on ammo again and I didn't want to be the guy 10 years from now that didn't have any while those darn guys that got scared and continue to get scared, have tons of it.

PMC $495 per 1000 55gr FMJBT
PMC $$685 per 1000 62gr xm855 FMJ

As I mentioned, that Tula works well in my BCM.  It seems to have a different velocity compared to other 55gr, as the point of impact is high at closer distances.
I mainly shoot with iron sights, so I don't much care as long as it groups decent.

As we're all here, I need a suggestion for long range accuracy.  I'm taking a high power match clinic and shooting ARs beyond 300 yards they suggest heavier bullets.  I'm kind of on a budget, but happen to have a quantity of both 69gr and 77gr Sierra .224 bullets, as well as H-335 and H-4895 powder.

Hodgdon has recipes for all the above, but am wondering if there are any recommendations?

Accuracy is not always increased with a heavier bullet. You need to know your twist rate of your barrel. If the twist rate is too fast, the bullet will be over stabilized, too slow and it's under stabilized.

Twist rate = 175 x (bullet diameter)^2/ bullet length.

You can use JBMballistics.com for advanced stability calculations.

example .224", 75 gr Hornady Amax, Length = 1.1"

175 x (.224")^2 / 1.1" = 7.98   A barrel with a 1:8 twist will stabilize this. 1:7 would over stabilize it but would be preferable to a 1:9 barrel which would under stabilize the bullet

There's no such thing as "hoarding". You were offered a price and took it. That's just a free market.

This is so absolutely correct it deserved a little recognition.    :-)

My barrel has 1:7, which is pretty much the fastest twist rate.  If I built a rifle length, I'm guessing 1:8 would be enough for the additional velocity gain from the longer barrel.
