what caliber, what load.
I finally got to shoot my 1889 with a tang sight installed.
After only a few adjustments, I was able to score 5 1/2", 6 1/4" and 6 1/2" groups at 100 yards. I could not see the yellow @ 100 yards so I was somewhat guessing where the center was since I had the targets tacked onto white poster board. I am not a Marksman so I call this good for this old boy!

I also shot a Reloder 7 group in my 44-40 Uberti, 7 1/2" Magnum frame revolver @ 25 yards
what caliber, what load.
I think all your targets are good, including the revolver. I was interested though in the vintage Model 1889. These groups are very good at 100 yards with iron sights, albeit a tang mounted one. I must say I prefer IMR 4227 although you haven't listed the velocities you got with that powder. Were they a little faster than the Reloder 7 ? Anyway very nice shooting.
If my wife asks....all guns cost five bucks and ammo is free !!!
IMR-4227 is a bit faster burning than Reloder 7 and creates higher pressures for the same velocities. For some reason my Chrono decided not to record those shots. I don't have mt data handy but I will certainly touch base when I get home tonight.
In the meantime, this might be of some interest! https://curtisshawk21.wixsite.com/44...keless-powders
SAAMI Max is 11,000psi/13,000cup
1910 era Winchester factory "High Velocity" loads produced 22,000cup (not safe for revolvers or 73' type weak action rifles)
1930's manuals listed loads that produced 33,000cup using 2400 (not safe for revolvers or 73' type weak action rifles nor probably old weapons in general)
MY 26gr of IMR-4227 with a 200gr hard cast .429 bullet produced 21,000psi (maybe close to 28,000cup) and is not pleasant to shoot!
Target 250, 251
26gr of Reloader 7 gives me 1,200 to 1,250fps pending which bullet I use, Speer JHP sized .4295 or a 200gr hardcast sized .427-.429. My chamber pressure findings ran @ 11,300psi with a soft hand cast .428 bullet
20gr of IMR-4227 gives me close to 1,350fps pending which bullet, @ about 12,300psi
IMR-4227 seems to like jacketed bullets while Reloder 7 likes both....in my applications

Heck savvy jack I was not paying attention to the forum, I saw 1889 and was hooked. I am working on an 1889 but mine is in 38-40. (made in 1892) I have just about everything working like its supposed to and shooting well, I will show her off when I am all finished up...
