RippSpeed Posted October 19, 2012 Share Posted October 19, 2012 With a incident that happen to my 5" Limited gun. I wanted to go on with building my open gun. I wanted to know the pros and cons of using a AET versus Standard barrel??? which one should I go for??? Link to comment Share on other sites More sharing options...
G-ManBart Posted October 19, 2012 Share Posted October 19, 2012 Pros: Better accuracy, more positive extraction, better feeding. Cons: Higher cost, they don't like cheap bullets (plated mostly), and they ususally take a couple of tenths more powder to get to the same velocity as non-AET (likely because the pressure is lower, or builds slower, with gain twist rifling. My guns with AET barrels will feed empty cases (one is a SS in .40, so that's saying something)...the ramp profile helps with that. Schuemann had a gun built with AET and non-AET chambered barrels. The barrel with the AET chamber threw cases 2-3ft farther than the standard chamber. I have two similar Open guns, one with, one without, and the gun with an AET throws the cases 2-3ft farther....that tells me it's extracting the cases better (chamber flutes help with this). I wouldn't build a 1911/2011 without an AET barrel if at all possible. In fact, I'm having a commander built in 9x23, and the only downside is I can't get an AET barrel for it.

wes777 Posted October 19, 2012 Share Posted October 19, 2012 http://www.schuemann.com/LinkClick.aspx?fileticket=m8%2fqS2Yz4bA%3d&tabid=67&mid=445 I have never heard of or seen anyone disprove this. Its usually the $$$ difference, but you want to shoot open..... So there you go. Link to comment Share on other sites More sharing options...
OperationHitFactor Posted October 20, 2012 Share Posted October 20, 2012 You should call Mike and ask him about which barrel to choose. He will help you pick the right barrel for your project. He is a good dude and won't sell you a barrel you don't need. For an Open gun I like the AET. Still like his standard 1:16 .400 SC for Limited builds as I shoot lead and plated bullets. Talk to your smith though, some like to cut chambers and feed ramps themselves. Not because there is anything wrong with the AET, but some just have been doing it a certain way for so long they are reluctant to change. Link to comment Share on other sites More sharing options...

pcschwenke Posted October 23, 2012 Share Posted October 23, 2012 The AET is awesome. I used on a 38 super long slide for PPC and it's crazy accurate. My next will be an AET for open class. Link to comment Share on other sites More sharing options...

When you say it requires more powder is it basing it on if your coming from a 1/16 twist barrel? Link to comment Share on other sites More sharing options...
Suicycle Posted November 12, 2012 Share Posted November 12, 2012 Gain twist usually need more powder for the same length bbl to equal the same speed. You don't have the spike in pressure as the bullet leaves the case because of the slower twist, just an easier path to travel. It is normal.

When you say it requires more powder is it basing it on if your coming from a 1/16 twist barrel? I've seen it with several barrels, but don't recall what rate twist they had. As mentioned, gain twist simply builds pressure slower, and lower, so you don't get as much velocity for the same charge. It's not a huge difference (typically), but it's usually there.

jmorris Posted November 17, 2012 Share Posted November 17, 2012 I have a few of the AET barrels and don't mind them for open but they don't like plated bullets and went with the classic on my last build. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted November 17, 2012 Share Posted November 17, 2012 Hello: I can tell when I resize some AET brass in my Case Pro. It feels like going over rumble strips. Thanks, Eric Link to comment Share on other sites More sharing options...

splashdown Posted November 25, 2012 Share Posted November 25, 2012 Rainier plated bullets worked great out of my 40 open gun with AET. 135gr at 1275 fps. Link to comment Share on other sites More sharing options...
