The standard Berry plated is rated at 1250fps and the hollow base is at 1500fps.

My first test with a 5" 9mm maximum load was without a Berry plated bullet.
I only had the lower fps Extreme 115gr plated rated at 1200fps and I pushed
it up to 1350fps on a average and a second load at 1305 fps, with full loads.
There were no plating "Specks" in the paper target, which tells me they held together
being 150fps over there recommended speed.

I will not do this again but it did work for my chrony testing of six powders.
Bullseye, w231, Green Dot, Unique, BE86 and HS6.
