So much excitement and raised blood pressure, simply by not reading posts before engaging mouth. The question had nothing to do with interchangeability of 223/5.56, and had you read my post of 01.48 PM the last paragraph states quite clearly that; The 5.56mm military cartridge fired in a .223 Rem chamber is considered by SAAMI (Small Arm and Ammunition Manufacturers Institute) to be an unsafe ammunition combination. SO THERE IS A POTENTIAL SAFETY IMPLICATION...... Which, had you bothered to read it, is what you appear to be, albeit hysterically, saying. If this is not what you are saying, then you apparently know better than Winchester, who issued the press release. IT WOULD APPEAR YOU KNOW BETTER BECAUSE YOU SAID THERE IS NO PROBLEM..... Now if you can gather up your teddies and replace them in the cot, maybe the thread can get back to the original problem of tight primer pockets. Ahhh!! the pot calling the kettle black :yp: , put you're specs on and have another look, In line with the original question, I offered a suggestion that it might be Military surplus ammo, Military brass, check the stamp, different primer etc, which if it's obviously now at the reloading stage has been fired, if that firing took place in a rifle chambered for .223 then there could be a risk involved for the user, I then presented an advisory warning of a potential hazard that not everybody might have been aware of, whats the problem with that? Guns+Ammo+Safety........All associated in my book. You seem to be confused as to whether to go with the Winchester release or with what you said earlier, have you changed you're mind about the possible safety implications? you're reply to my post was very firm in it's conviction that there were none, and I quote, " Secondly, there is not a problem, "potentially fatal" or any other wise" , now are you saying there is a potential problem, ref the Winchester release, make up you're mind there is or there isn't. Why you have chosen to slate my well intentioned advisory warning is known only to you and you're psychiatrist, threads sometimes drift slightly off topic but when personal safety and that of others around us is involved how can that be a bad thing, when it comes to weapons handling and safe shooting we as responsible holders of SGC-FAC should surely seek out all the information we can. If you all ready know it all then well done you.

Here you go for the non believers that 5.56 can be POTENTIALLY, dangerous in a rifle chambered for .223.......I'M NOT STATING THAT YOU'RE CHAMBERS GOING TO EXPLODE AND KILL YOU, BUT IT MIGHT, so be aware of the possibility or go through life thinking it won't be me, that sort of stuff happens to other people, besides which bob300w said it was OK. Of course these might be rubbish as well!! http://www.thegunzone.com/556v223.html http://www.gunslot.com/forum/223-caliber

Firstly, 223/5.56 interchangeability was not the subject of discussion. Secondly, there is not a problem, "potentially fatal" or any otherwise, (********) with using reloaded 5.56 cases in 223 chambers, it is simply a matter of reducing the powder charge to accomodate the reduced capacity of some military cases, not all manufacturers cases have a reduced capacity, caused by the use of thicker brass, some use the same cases for military and civillian use. In case anyone is concerned after reading the previous post, Winchester's press statement is as follows, it should be noted that this applies to factory loaded military ammunition only (referred to as 5.56), not reloads, that were the original discussion; The 5.56mm and .223 Rem chambers are nearly identical. The difference is in the "Leade". Leade is defined as the portion of the barrel directly in front of the chamber where the rifling has been conically removed to allow room for the seated bullet. It is also more commonly known as the throat. Leade in a .223 Rem chamber is usually .085". In a 5.56mm chamber the leade is typically .162", or almost twice as much as in the 223 Rem chamber. You can fire .223 Rem cartridges in 5.56mm chambers with this longer leade, but you will generally have a slight loss in accuracy and velocity over firing the .223 round in the chamber with the shorter leade it was designed for. Problems may occur when firing the higher-pressure 5.56mm cartridge in a .223 chamber with its much shorter leade. It is generally known that shortening the leade can dramatically increase chamber pressure. In some cases, this higher pressure could result in primer pocket gas leaks, blown cartridge case heads and gun functioning issues. The 5.56mm military cartridge fired in a .223 Rem chamber is considered by SAAMI (Small Arm and Ammunition Manufacturers Institute) to be an unsafe ammunition combination. Point out to me where I mentioned 5.56 reloads !!! I stated that you should not use 5.56 military surplus round in a rifle chambered for .223, because of the POTENTIAL safety implications. As well as 'Leade' info, you should also have taken the time to make a mention of the MASSIVE difference in chamber pressures, 58000psi .223 as opposed to 78000psi for the 5.56, if you are happy to chance you're breach exploding in you're face then bash on mate. AN EXPLODING BREACH CAN POTENTIALLY KILL OR BLIND THE SHOOTER AND ANYBODY ELSE IN THEIR VICINITY. Thats a real possibility I've not made it up for dramatic effect, what you or anybody else chooses to do is up to them, but it is highly irresponsible of you to dismiss the very real danger you so very daringly choose to brush off as nonsense. http://en.wikipedia.org/wiki/5.56x45mm_NATO As for reloading a 5.56 military surplus case of course you can!! as you said the brass is usually slightly thicker meaning a reduced load in the reloaded case, the point I was making is that if the rounds are military surplus then the primer type and flash hole will probably be different NOT THE CASE, I asked Fleabag as others have to check the stamp on the case head to eliminate the possibility that it was 'mill spec ammo' therefore if it is that could be his primer problem!!!!! and I thought it an opportune moment to point out the POTENTIAL, NOT GUARANTEED TO HAPPEN, danger of using military surplus ammo, 5.56 in a .223. So much for trying to help somebody out. Anyway Fleabag hope you get it sorted mate any other enquiries should go direct to bob300w because he's the only person on here that apparently knows anything.

I've reloaded loads of winchester .223 cases, with CCI 400 (silver colour) and Remington 7 1/2 BR (brass colour) primers never had a problem. I think the 64gr rounds must be military surplus, it's a bit of a coincidence that, thats the weight of round the military use and they are FMJ. Check the stamp on the base. if they are 5.56 military surplus you could be in for a potentially fatal experience because of the excess pressure of 5.56, you should not use 5.56 in a rifle chambered for .223, (before anybody jumps on that statement, their are exceptions AR15 derivatives etc.....)

I've got a .223 T3 Tactical 1-8 twist and it shoots anything from 50gr right up to 75gr. What do you mean by "not very good through it", group size? Sako 50gr shoot 2" to the right from the POA in mine, but still group sub 1" @ 100yds.

There you go, not racist at all, it's in the Oxford Dictionary of slang, it's a verb, simply means stolen. <The term is considered to have negative connotations; even when it refers to others, many people still consider it to be derogatory and offencive. "*****" is frequently used as an adjective, as in "he lives on a ***** estate", "those clothes look *****" or "(name of cheap shop) is a ***** shop". However, "*****" is also occasionally used as a verb, a synonym for "steal", as in "Someone's pikeyed my bike".> It's only slang? unless it's used in the context it's being presented in this thread, anybody that reckons it's not being used in a derogatory way when mentioned in this thread is kidding themselves on. you have taken a snippet of the wikipedia explanation to explain you're understanding of the word, here's the link to the full version, *****, http://en.wikipedia.org/wiki/***** You could also present the same kind of argument when being selective about what parts you pull from the information at hand for these terms, ******, just take out the parts that point to it being offencive, http://en.wikipedia.org/wiki/****** Poof, Same as above, take out the parts you need to to present a lame argument, http://en.wikipedia.org/wiki/Poof yid, http://en.wikipedia.org/wiki/Yid You can pick as many Racist, Derogatory verbally insulting terms as you like and with a clever bit of word manipulation you can present them as harmless everyday sayings (that don't mean anything by cause there not really insulting)....Are they Fatty, Baldy, Four eyes. To label an entire people with the same brush is narrow minded to say the least, there are good and bad individuals/groups of people in every community in the country. The true Romany's have family lineages that go back centuries, Most are proud respectful people with strong family values driven by the ethos of 'a mans word is his bond', unlike some of the modern day 'new age' travellers whom everybody automatically associates as being Gypsy. Ignorance is bliss and often it's far easier to jump on the band waggon and join in with the public stoning than to actually learn what you're talking about.

As per you're title, shouldn't that read as, Three Gun,Gun,Gun Cabinet then?? Sorry couldn't resist.

Are you measuring the OAL to the tip of the bullet or the ogive with a comparator?

I've got all three, .22LR, .17HMR and .223, they all have there place in the gun cabinet as each is suited to the particular types of shooting I do, it really depends on what you use them for.

Got a quad in 17HMR, absolutely outstanding rifle, never misses a beat and ultra accurate, if you are willing to spend that bit more than a CZ, get one you won't regret it, I,m not knocking the CZ's I've got one in .22LR and it's a great wee rifle as well.

Doesn't play on my PC, damn!

Do you use a combo electronic dispenser/scale, i.e. RCBS Chargemaster 1500 or Lyman 1200 DPS 3, if so any recommendations between the two OR do you do the powder measure, mechanical scale method.....

They don't stop at once a year!!! Hence the phrase breeding like Rabbits.

Thanks for the replies.

Is it the variable (dimmer version) 170?
