Seems to be a lot of variation in FPS on this thread. My 223AI has a 22" tube, and shooting 40's I am getting around 3850 with 30grs of H335.

My thoughts also, seems a tight chamber can give you an extra 300 to 400fps because you can overload them. Very surprising since most of the time I only see around 30fps speed increase with .5 increase in powder with a 26" and 28" barrel. Without a custom chamber and without custom bullets the best accuracy loads with speed in our 223s is right around 3650fps with a 40 gr. Then again it could be my chrony. We are shooting them across a Chrony Alpha master and a Millennium and either one is within a few fps of the other. I have attained speeds up to 3700 with overloads but the accuracy wouldn't be there. I might also add I've never saw a Hart Barrel that wasn't a tack driver and while I've only seen a 1/2 dozen personally and got to shoot a couple should I chose to build a rifle it would be my first choice. If you added 4" to you barrel you would be doing close to 4000 with your's.

I can hit 4000 with my 22-250AI, so I never really cared what my 223AI was doing. That being said, I still cannot hit the magical 4k with my 204...It too is running around 3850-3900 with 35's and a 24" tube. Coyotes don't seem to care though. smile

my .223 AI rifles have 1-8" twist (22.5" Brux) and 1-7" (22" Hart). my interests lie more with getting 2850-2950 fps with the 75 grain A-Max. easy enough to do in my AO, but this gets me to 1K at mach 1.125 and 34 moa.

dont' get me wrong, the fast twist and the 55 grain V-Max (case forming load) shoots MOA at 500 meters, and the fast twist aids in making varmint confetti, but hinders velocity somewhat. i let the rifle tell me where maximum is, and i work with that. if that is less than some others get, so be it. the LRF has reduced the need for max velocity IMO.

Got just over 3800 out of a Rem 700 with a 26 inch tube that I used to own, 40 gr V-Max using AA2460, very, very accurate as well.

Using the new Nosler 35 grain lead free might gain a few more fps.

no one mentioned the 30 grain HP Bergers.. they are as long as a Nosler 40 grain BT... they can be run at 4000 fps...

I have hit 4000 fps consistently with a 40 grain bullet using RL 7.
It had good accuracy also... but most of my needs don't require that MV...

heck I run most of my 22.250s at the upper ends of what most people run their 223s....

I like stretching out barrel life more than getting MACH 10 velocities...

Seafire: I also live by the credo - don't burn out your barrels!
But consistent 4,000 F.P.S. shooting from a 223 case ain't gonna achieve that.
I also get great accuracy and lethality on Varmints with bullets at much lower velocitites.
Most of my 220 Swifts are "pokin" along at 22-250 velocities as well.

P.S.: At the just concluded Missoula, Montana Gunshow I saw several sets of 223 WSSM dies for sale!
One set I nearly bought was a new set of Redding dies in 223 WSSM with an "asking price" of $20.00!
Another set of RCBS dies appeared to be new/as new and had an asking price of $15.00!!!
I don't have, nor do I want a 223 WSSM, but I was tempted to buy those dies anyway.

My experience has been that the lighter weight is offset by the longer bearing surface. I reach the about the same velocity and pressure with 36g Varmint Grenades as I do with 40g V-maxes. Perhaps the Nosler will yield different results.

The whole idea is ludicrous. Absurdly dangerous, to boot.

If it could be done safely, every ammo maker would be doing it already.

I have noticed bargain basement prices on WSSM die sets and brass locally also..... for anyone who has them, seems like they had better stock up now... won't be around long...

I never warmed up to the concept of the WSSM either...

played with the idea of necking a 25 WSSM to 6.5 mm... but after checking out powder capacity found out that it holds no more than a 260 Rem held... so why bother?????

The 270 WSM, on the other hand, is kind of a neat .264" cartridge.
