I thought I'd share my chronometer results for 32 S&W Long, in case anyone has an interest. This was a Brass Arsenal Mold .32 98 Gr SWC Keith. I powder coated using Powder By The Pound. These were fired from a Charter Arms Undercoverette with 2" barrel. Starline brass. Accurate No 5 powder. CCI 500 primer. Load data was from the Lyman Cast Bullet Handbook, 4th Edition; Saeco #326 100 gr. ProChrono chronograph.
I am not that great of a shot. I was kneeling shooting off hand. It appeared to me that accuracy improved as velocity increased, with 3.5 gr and 3.6 gr being roughly equal.
I hope to get around to loading for the 32 H&R Magnum. Lyman shows the same powder charges with a 1" longer barrel, getting different results.
