Got some results in for the thicker jacket, .224, 69 gn open tip, flat base
I do not have a .223 but a mate up the road was willing to test them. I wanted to test these projectiles in a fast twist barrel and so loaded up 15 rounds and three foulers. The rifle is a WFA-1 with a 1 in 8 barrel. Basic case prep was done, uniformed primer pockets, cleaned in SS pins, and flash hole deburred internally, trimmed to length and weighed.
Rounds were loaded with a min book load from the ADI web site of 24.0 gn of 2208. 2208 was used as it was the only powder I had in stock suitable for .223 As I had a dig around in my mystery bucket of old brass to find some cases, I came up with 10 cases that were nickel plated with the same head stamp and weighed to within .2 gn of each other and 5 plain brass cases again within .2 of each other with the same head stamp as the nickel plated brass. The three foulers were various cases.
As the pics show the 10 rounds that had nickel plated brass shot pretty good groups.
The 10 rounds were fired in two groups of five and each group had a flier but the shooter called the flyer in both instances. Group one was .925 and group two is a hair under 1"
Of interest is the third group that was plain brass cases that were loaded exactly the same as the other 10 rounds. That group was just on two inches.
My main aim was to test the projectiles to see if they would hold together in a fast twist barrel and on that note all projectiles made it to the target, there was no key holing.
For a projectile I made out of scrap .22 mag brass that was dug out of my mystery bucket and to get groups around a inch will do just fine. I do not shoot the heavy pills but it is good to know that I can build them and the cost is minimal. It did take a bit of work to start with and the experiments are still being done. I have some being loaded by a bloke in Qld and they will go through a Tika T3.
This is only three groups and by no means conclusive in regards to accuracy of the projectile but it is promising, they held together and I made them.

Swaging your own projectiles is the ultimate in flexibility.
