I'll probably get blasted for saying this, but I tried swaged aluminum years ago and had bad results. I used 2219's and they ended up being weak right behind the taper. If I hit a rock or hard stump while stumping, they had a tendency to bend in that area. These were swaged by a reputable place that did a lot of business in the late 80's early 90's. I found the 5 degree insert adapters to be a lot better and more economical deal. These were made by Easton and Flitemate, and I found the Easton's to be the best. From the shoulder of the taper they fit down into the shaft 1 1/8" which is longer than the Flitemate's. I have found this acts as an "internal footing" that makes your arrow wicked tough on the front end. I know of several sources to get these, and they turn up on the auction site all the time. I bought a couple of hundred packs a few years ago in my favorite sizes, and never looked back. The Easton's also come with a snap-off tip that allows for full length use or a short taper for use with a bleeder insert.
Obviously, this is just my opinion/results, but I find it funny that everyone is now trying to figure out how to "foot" thier carbon arrows and get better service out of their aluminums. Seems to me that technology has been out there for several decades.It would also seem this would accomplish the same intention as swaging, while still allowing for the flexibility of cutting shafts longer, changing to an RPS insert, or whatever.
