Which .223 Reamer?

[AR Shooter]

Am shooting a Ruger No.1V in .223 and finding that the factory chamber is throat is short. Set up for AR 'magazine length' loads. When shooting 80gr bullets (SMKs or Hornady) am finding that I either have to compress the 24.5gr of RE15 or reduce the load. Am wondering if I should just run a Wylde chamber reamer in there, or is there a 'better' reamer out there? Plan is to shoot 75-80gr bullets (many to test - 77gr SMKs & Bergers, 75gr Hornady ELD-match, etc.). Barrel is a 24" length with an 8" twist. And, no.......... have no interest in shooting lighter weight bullets as the majority of my shooting will be F-T/R at 600yd.
Thanks.

Throat it for the longer bullets.. then when it is time to replace that barrel, think about a reamer.. i just bought a 223 ISSF reamer.. but in the past i had always used a Wylde chamber and throated it for the longer bullets.. worked just fine!

Compass Lake Engineering reamer (CLE). 223 Wylde is just a compromise that allows both 223 & 556, it is not built for accuracy.

... compromise that allows both 223 & 556...

I love these comments, though they are common everywhere...

So riddle me this, which of the following loads is a 556 and which is a 223?


an 80Amax over 24.5 grains of H4895 in LC brass
a 90VLD over an even stouter charge of Varget in Federal Brass
an 80 Nosler loaded over 24.5 grains of Varget in WCC brass

I bet I know .

Go ahead and pile on. This was what 2 of the country's top Service Rifle builders told me. I never said it wouldn't shoot. OP asked about reamers for 223 long bullets in magazines. The CLE reamer does that. My opinion, take it or leave it. I am not here to argue.

The point I'm trying to make is that the only difference in a 556 and a 223 is that one (the 556) has a higher SAAMI pressure, and in the SAAMI reamers one (the 223) has a slightly tighter chamber drawing and a slightly shorter FB.

In a custom barrel, what is your maximum pressure spec?

If you use a Wylde or some other custom reamer then is it a 556 or a 223? I guess it's neither?

In the case of my references above I guess it would depend on the chamber you loaded the bullet into...The chamber in my bolt gun is a 223 Remington Match chamber with a .169 freebore, so those are all 223s when I shoot them, (well, except that the brss was 556 brass to start with) but if I throated my AR with a Wylde chamber to accept them and fired them in it, would they then be 556s?

The whole 223/556 thing is a tempest in a teacup caused when the military spec'd a slightly higher pressure for their ammo, and thus military or 556 brass has to be able to take a slightly higher max pressure, and anyone who reloads should get that.

It's just semantics, they are one in the same. Do you really think anyone out there selling ARs marked 223 is selling something that is unsafe with ammo marked 556? Is the ammo that is marked 556 really any different at all from the ammo marked 223?

Anyone who understands the least bit about reloading and/or custom chamberings should understand that.

OK....... off goes my barreled action and a couple of rounds to my gunsmith for a bit of throat-work. Only have about 100rds down the barrel, so will do so now, rather than waiting for the next barrel.
Thanks for the replies.

Good choice.

See that the 'ISSF' reamer with a 0.169" freebore is recommended for 90gr VLDs. As I won't be shooting anything heavier than the 80gr SMKs or Hornady or 80.5gr Bergers in this rifle, what is the optimum amount of freebore for these bullets?

.100" will let you shoot the 75-80s pretty well.

i have that reamer.. i may be selling it very soon..

Having used both .070 and .169 freebore in my ftr rifles with 80's I will never use anything less than .169 now especially if bergers are on the menu.

There is about .115 of bearing surface of a 80 smk in the neck (.030 jump) with a .169 freebore. With bergers there is quite a bit more in the neck.

With the extra case capacity you get with the .169 freebore I believe there is another node well above 3000 fps that won't destroy primer pockets. If I wanted to compromise (because of the 80smk's) I might do a .130 at the least.

I can jam 80s with the 169. If you want to shoot 75s or ligher then the 169 will be on the long side.

If you are going to shoot F-TR and you are not shooting the 90VLD you are probably spotting the competition of equal skill 2 to three points per weekend. Considering that the first 5 places in F-TR at the Bergers last Feb were 599-38, 599-32, 598-41, 598-28, 597-33 I don't think that is a really good plan.

Per the 1st post, this is for my Ruger No.1V with a factory 24" barrel. Don't think I will be winning any F/TR matches with this rifle. I do want to be able to shoot 68-69gr bullets in this rifle at our all-off-hand 100/150/200m gong match. Looks like it would be good with 0.100-0.120" freebore.

 

[XTR]

my bad, confusing this conversation with another build here

 

[AR Shooter]

No problem. That's pretty much what I figured.
The dedicated F/TR turn-bolt rifle from the other thread gets the ISSF reamer 'treatment' (0.169" freebore).

Even with the 68-69gr range of bullets the the .169 reamer works good. It's been a while, but if I recall correctly the 69 smks still have about the same amount of bullet in the neck as an 80 smk( I remember being surprised)

The Berger and hornady 68-70gr bullets have are even more suited for the .169. Just my thoughts...
