Serious question: other than a weight difference, what advantage or disadvantage does one material of action make over the other? This is based on the custom action manufacturers only. This will be for a new F-Open .284 build.
When Kelbly made the Golden Bear I called Ian over there and asked them why they would make one in steel. "It's what the customers wanted.", was the answer I got. It doesn't offer any clear advantage over the aluminum. It's just heavier.
Other than the weight/cost, I don't see any difference.
I believe the alloy receivers slightly subdue harmonic vibrations. I've had about 1 or more of most receivers manufactured, but if I started over again it would be a Kelbly based Panda.
That would be interesting to see an actual experiment. Not sure how you would test it but interesting. I only say this because when it comes to bicycles, some people tout steel framed bicycles as smoother over bumps than aluminum.
Well, its probably more scientific than a bunch of hipsters riding around in the bicycle lane.A few years ago I was visiting with Ed Shilen. We were talking tuners. He had his rimfire set up in his rest. He put a set of headphones on my head It is an amplified stethoscope. He took a pic of his tuner setting and moved it several turns. He told me to lay the probe behind the tuner and tap the barrel with a small brass rod. He told me to keep doing that and adjusting the tuner until it was just a dead sound. Doing that I had adjusted it back to where he had the tuner set.
It ain't scientific, but at home with my own amplified stethoscope, but on LV and HV rifles each had a distinct different sound with an aluminum receiver.
Don't ask me which shot better as they weren't mine. It means enough to me that if I buy another receiver, it will be aluminum.
