Default Is a 17-223

that much faster than a 17 Rem.? I remember when the 17-223 came out and then shortly thereafter the 17 Rem. came out and became all the rage..........well sorta. Now I'm hearing how the 17-223 will launch a 30gr. bullet close to 200fps. faster than a 17 Rem. and the 25gr. bullets are even faster than that in the 223 version. To be honest, that is new news to me. I thought I was somewhat on top of the 17 cal. stuff and now it appears I'm not.
The main reason I'm interested in this now is this. If I can launch a 30gr. bullet from a 17 Rem. at close to 3800fps and a 17-223 will do it around 4000fps, then why would I chamber for a 17 Tac. or a 17-204 when the 17-223 has me pretty darn close to their velocities.
Those that have or had a 17-223 what is your experience? Is it really that much faster than the standard 17 Rem?

I think most of those gains are due to the only the 17 Remington having published max pressures and load data. Put the same pressure in a 17 Remington and you will be much closer to what the others are claiming. Larry

Hodgdon's Annual Manual 2012
Shows the 17-223 and the 17 Remington exactly the same
in most all powders, with 4000fps possible with 25 gr bullet.
A touch over 3800fps with the 30 gr with the 17 Remington.
It does not list 30gr in 17-223 but I would assume the same. Kenny

Lightbulb Since.....

....the 17-223 has a greater headspace than the 17 Rem, and greater case capacity, I'd think it would do better......especially with heavier 30 grain bullets. I'm not sure by how much, though.

It's been a looooong time since I've fired a 17-223.

Note that the 17 Predator is based on the 223 case.

I'm no expert but I seem to remember an article in handloader last year about the 17 remington. They mentioned it was a more effecient case design then the 17-223, slightly better velocity because of the better design in the case. (maybe shoulder angle?) I dunno.
They said many guys complained when it first came out. Something about a new cartridge when you could just neck down a 223 to 17, but it didnt give you as good of velocity. So remington decided to go with their 17 design.

All that to say, the article made it seem like the 17-223 was actually slower then the 17 remington, and thats one of the reasons it took off and was so popular. More work, purchasing new brass, but better according to them.

As a former owner of both at the same time, I can say that over a chrony one looks just like the other when loaded to reasonable pressures. Neither one has a big advantage in velocity unless maybe you can find some of that magical Lake City military brass that's apparently floating around. I've only been able to find the regular stuff when I buy it going clear back to the the early 1980's.. Not sure what I've been doing wrong there....

In addition - Some folks will tell you that you can get better quality brass from regular 223 brass for the 17-223, but I've never seen that as a big advantage either. I've been buying 17 Remington brass since the 1970's and I've never seen any that was even close to the equivalent of some of the internet horror stories you read about it as being the norm. All of it has been very serviceable. Granted, some batches required a bit more prep than others, but that's definitely not anything unique that doesn't happen occasionally with most other kinds/calibers of brass, in my experience.

Currently I own five 17 Remingtons. Both of the 17 -223's went down the road quite awhile back.

Having believed faster=better for a long time-a couple of swifts, 264 Win and my favorite 270 Wby I finally just started looking at trajectory tables and more importantly wind drift. At which point I realized once you're over a certain velocity it only amounts to a few RCH way out there.
So once I get the take off .17 Remington barrel dialed in on the M7 it will become some sort of 20-222 variation.
