Berry's plated bullets question

I'll take a guess-
The alloy in the bullets cast from wheelweights is likely harder than the alloy in the swaged and plated bullets and therefore better resists impact with the rifling. Softer bullets can strip when they hit the rifling and not be properly stabilized.

But in your situation the best way to answer your question is to do some experiments. If you get higher than 1200fps with good accuracy then nothing wrong with doing that.
