I assume you refer to the 4.3 gr/Unique that Lyman has listed for something over 50 years? 1100 FPS is a bit optimistic. I have shot thousands of 4.0/Unique with the 3118 and they chronograph about 950 from my Model 16. Pressure signs with the 4.3 gr. were, well, let's just say that you should never see "pressure signs" in any standard revolver cartridge.

For whoever called the .32 H&R a "Wannabe Magnum" let me tell you about that. I have worked up loads for my 4" Ruger SP-101 with Lyman #3118 @ 112 gr. that will honestly chronograph within a very few FPS of 1400 FPS. No pressure signs and the gun shoots like a rifle. The 3118 has the same sectional density as a 158 gr .38 bullet! I defy you to get 1400 FPS from a 4" .357 Magnum revolver with a 158 cast bullet! No, the .32 H&R is no "Wannabee", it is the "Real Deal" in guns capable of using loads to it's full potential. And, NO, I will not shoot those in my 631, but I have gotten it safely to about 1200 FPS with the same bullet. And, likewise, NO, I will not post what the load(s) is/are.

And note: 1400 FPS, plain base cast bullet, Saeco Green lube, and no significant leading! Anyone who says you can't push a cast bullet over 1000FPS without terrible leading simply doesn't know what they are talking about and/or have no real experience shooting cast bullets. Bullet fit and lube are everything, alloy hardness and gas checking have virtually nothing to do with whether you get leading or not.
