For 40-82 reloads, I've used IMR 4198 (24.0 gr.), IMR 3031 (34.0 gr.) and have settled on Unique (14.0 gr.) with a 1/4 TP wad. Until the Fall of 2005, I lived in Ontario and found that IMR 4198 and IMR 3031 wouldn't always ignite when shooting at -20 C (primer always did though, dumping mostly unburnt powder through the action when the case was extracted and leaving a bullet part way down the barrel - real fun at -20) so changed to using Unique with a 1/4 TP wad tamped on top of the powder - solved the problem. Bullet was always a cast Lyman 403169 (245 gr.) of various alloys but lately #2 alloy. My 1886 was made in 1887 and from info. gathered from various sources, the rifling in these early, softer-steel barrels will not tolerate many jacketed bullets before it shows significant wear - don't know if it's true but since my 1886 has a decent barrel, I want to take care of it.
