I have a stash of the old 200 gr Speer "Flying Ashtray" bullets that I'd like to reload to get top velocity from. Speer's manual gives a velocity of 984 with 7.3 gr of Unique and 967 from 7.0 gr of Universal. These seem to be the top two(excluding Blue Dot) contenders. I don't want to go max but close to it to reach a 950-1000 fps from a 5 inch barrel.
The data Speer shows for this weight bullet was taken using a Sig P220 so, I'm assuming a 4506 with a somewhat longer barrel would give the above velocity without having to get too close to max. Can anyone recommend these powders or another that would give safely the velocities mentioned?
