I've used 2gr. of Bullseye with the Bullet Barn 78rs. bullets, as suggested by josquin above, in several little 32 ACP pistols, over several years, and found that I only had to size the bullet down to .309" for easy loading in a tight chamber for one pistol (I seem to remember that it was a late civilian version of the 1935 Beretta).
In various others, including Savage, Browning, Walther and Webley they shot fine as supplied, and made for REALLY inexpensive shooting out of inexpensive little pistols.
