off topic ammo questions. 1. Can I 'safely' use winmag in a weatherby 300? 2. I know the winmag cartridge will fireform--is it then useless for reloading?
Originally posted by fierofool: I see much mentioned about the twist ratio in for sale ads I've looked at. I expect that a 1:6 would be more accurate than a 1:8, but might reduce the range. Am I interpreting that correctly?
No. Twist rate effects the bullet weights it can effectively stabilize. 1:7 or 1:9 are the most common that I've seen. I'll have to look up which is better for heavier ammo (get them mixed up), but one is better for lighter 55-62 grain bullets and the other would be better for 62-75 grain, etc.
"1-in-7 Inches This is the twist chosen by the military since the switch was made to the M16A2—and the 62gr. M855 cartridge—in the 1980s. This twist is found on the M4 carbine, the M16A4, the Mk12 Special Purpose Rifle and even the HK416. Its ability to stabilize tracer rounds in-flight is one of the reasons that the military chose this twist rate.
This barrel will stabilize bullets of up to 90 grains, and can handle the 70- to 77-grain bullets at just about any velocity, which makes it well suited for carbines with very short barrels. If you want a Mil-Spec clone, the 1-in-7 twist is the way to go."
Like mentioned above, a tighter twist rate (i.e. smaller number) is meant to stabilize heavier projectiles. Barrel length also comes into play. So if you have a really short barrel, you should lean toward a tighter twist rate. And conversely, a longer barrel can impart more spin on the projectile, because it spends more time traveling through the barrel.
Since the powder charge has a fixed amount of energy, any energy used to spin the projectile is subtracted from the energy used to propel it. So tighter twist rates do reduce velocity. But the effect is really minor. I wouldn't worry about that. However, if the twist rate is super-tight and you shoot a light weight bullet from it, there is a risk of spinning the bullet so fast that it actually tears apart in flight. Try to imagine spinning a cabbage so fast that the leaves start to fly off.
Long story short, it would be a good idea to figure out the range of projectile weights you'll be using, and pick a twist rate that's a happy medium.
How is ATI? This seems cheap, maybe not so great, thought I'd mention it since budgets came up: ATI Tactical Omni Hybrid Maxx LTD , AR-15 Rifle - 5.56/223, 16" M4 Barrel, $519 on sale for $399
Having built many custom AR's and worked on/with even more of them, please stay away from the ATI polymer lower receivers. I have dealt with many that have cracked/failed, usually near the take down pins. One at the buffer tube. They are not designed for everyday use. I have worked with New Frontier Armory polymer lower receivers and have never seen one crack or fail.

Adding, I do have a polymer lower. It is Kevlar reinforced. I have it on my M16 Clone. It has not failed me. It is a custom built/milled lower receiver. It has been used with all my off caliber Upper Receivers, except my Beowulf. All the rest of mine are 7075 aluminum.
Luckily, the ones that have come to me were not as bad as what randye posted. The owners all noticed the failures before it got to that point.

I met with an individual who had an unfired rifle he built from components. $550 without a written warranty or bill of sale. I had my PD Chief run the serial number of the lower and it was clean, but absence of paperwork made me walk away.
I found a complete Anderson at Fuquay Gun in Fuquay, Varina, NC. $480 to include shipping. Bill of Sale and Warranty. $15 transfer fee at my local gun room.
Thanks everyone for all your input. I learned a lot from you all, and also from Nelson in private communications.
Joe, I'm not aware that they need to be registered, or any gun, for that matter except when it's a sale from a licensed dealer. I believe sales at gun shows are even exempt. Sales and gifts between individuals are exempt. You can buy a kit and assemble a rifle without registration. I've seen some ads in my searches that listed complete kits and stated that they were untraceable. A couple of mine are registered to me because they came through licensed dealers, and also because I want them traced if they're ever stolen.
I have several firearms that were manufactured and sold as complete firearms by name brand manufacturers, and they don't even have a serial number on them.
2.5, I bought mine online through a link from Georgia Gun Owners, Georgia Armslist.
The AR looks good sitting in my cabinet. Unboxed it and put it away. The local gun shop kept or disposed of the manual. I've downloaded it but haven't had the time to disassemble the rifle to lube it. I also need to get some sights and wait for the Sheriff's range to open for the season.
Picked up 10 Magpul 30 round mags for $80 and an ammo box with 500 rounds for $165.

Charlie,
You may want to try a relatively inexpensive red dot sight and see how you like it. I think that it would fit your needs very well. BTW, is your AR a flattop or does it have a built in carry handle/sight combo?

That is cheap man. Was gonna say I have an unfired new one for sale, but WAY out of that price range. Not the same type of sporting at all either though. This is 18" heavy all USA.
Yes, mine is a 16 inch, but it's all made in Kentucky. It's basically for occasional target and for home defense. I don't hunt any more since I wouldn't be able to climb into a stand or drag a deer out of the woods.
Randye's 3rd photo in the failed pictures above says it all about polymer. "PLUMCRAZY" on the side.
Hudini, it's a 5.56/.223 chamber. Not specified as a Wylde, but Fuquay assured me it was perfectly safe for both calibers. Talking with my son in law, we were wondering if you could intermix rounds in the same magazine.
Oh yes. They are physically identical rounds. The difference being the powder with the 5.56 NATO producing much higher pressures. Your gun might cycle a tiny bit faster with the higher pressure or maybe even kick a tiny bit more (if ARs can be considered to have a kick at all)

I just tried your link and got a warning about the site certificate.
Never had a problem, try just searching "slickguns".
Yeah ammoseek is another one, some don't list certain stores so hitting both can be useful.
Here is the first page from slickguns on the Ar556 ( for example), you couold search the sellers pages (listed on the right) some of these are sales that will only pop up if you go thru slickguns to get there though:

I tried slickguns just now on the pc and got no warnings. I was on an android before.
Many of those listed are comparable to what I have, except that they also include sights, which mine didn't have. Still, it's all in hindsight, now and I'm happy with the one I purchased. Probably will never purchase another. Ammo might be a different story, though.
My Beowulf will function on my 5.56 lower just fine. No issues. My 7.62x39 upper will function on my 5.56 lower. With certain exceptions to calibers (pistol calibers and rimfire) most upper receivers chambered in non-standard AR calibers will function fine on a standard AR lower receiver. I have dedicated lower receivers for each caliber so I can tune the entire rifle to each caliber, but they all will swap if needed.
I took the rifle down to the Sheriff's Department range a couple weeks ago and put 60 rounds through it at 75 yards. The target still lives. Nary a hit on a silhouette target. Of course, I didn't have any sights on the rifle, either. They didn't come in until this past Friday.
