Historically:
9mm: Cor-Bon 115+P (the original one with Sierra Power Jacket bullet)
.45: Fed Hydra-Shok (pre-HST) 230
.22lr: CCI Stinger, Velocitor, and Quick-Shok(CCI)
.22 Mag: CCI Maxi Mag +V (recovered dime sized mushroom once)
these next ones, without real preference, just some I remeber using, in ctg.'s off the top of my head I've owned:
.357 Mag- Federal 110 (?) JHP, Glaser Blue when staying in a trailer, Buffalo Bore HC 180's-outdoorsman use
.40- Federal PPD 165 gr, something in 135 gr also (Golden Sabres? or the other way around), Triton Hi-Vel on occasion
.44 Mag- PMC Starfire? Today would be ProLoad light mags (.45ACP ballistics)for SD and Buffalo Bore heavy hard cast for getting off the beaten path. Hornady LeverEvolution for stetching range. Maybe Strike 3 for SD also if still made. And CCI snakeshot for more survival utility and Cottonmouth killing. Lots of versatility with this ctg. and load options
.223- Federal 40 gr Varmint JHP's, WWB 55 FMJ's. Did a lot of shooting with old 1:12 rifling, liked the faster stuff anyway.
7.62x39: Wolf Steel case JHP and FMJ
12 ga: "Blue Peters Whistlers" 00, Rem. Slugs and 00. Federal & Winny big box 7.5 bird for plinking. The Peters are the best deal without ordering cases of Estate or S&B
some other cal.s I've owned too but these stick out.
What I put down for .45 and 9mm were definately what I preferred, maybe due to a little of Marshall and Sanow I took as gospel back then. And CCI aluminum Blazer for both for practice, sometimes dirty Magtech .45 FMJ when on sale. That Magtech made me clean my SA after every use, filthy, sooty residue. Magtech has a couple lines of economical JHP (incl. an all copper hollowpoint), but around here .45 ball goes for .50 a round.
The .45 Hydras fed well and shot to point of aim, same as ball. Now the Cor-Bon 9mm, did not always run well, maybe something with increased slide velocities, as bullet profile was not bad at all. I had a Star Ultrastar that would choke on em 3-4 times out of a 9rd. mag. Never missed a beat once with ball. I sold that gun for almost nothing. Wish I still had it and some Powrball or the Hornady version. Different phiosophies: light and fast 9's, slow high momentum .45. I did wanna try the .45 Aguila 117gr., but never could find it, and was happy enough with the Hydras that hit like bowling balls. On the flipside, I'd never go above 124 gr. in a 9mm auto. 147's only in a carbine.
There were a lot of semi-exotic JHPs back then, under engineered compared to today. Now there is a wide selection from several mfg.s many with different lines of defensive ammo, with weapon specific technology(e.g., Gold Dot short barrel). There are a lot of types past and present that I've not tried but would like to.
Nowdays you can also get good stuff for oddball or surplus cal's like 9x18, .30 Tokarev, .38 Super, 9x23, 10mm, etc. Alot of the smaller ammo companies (RBCD, Double Tap, Georgia Arms, Magsafe, Extreme Shock, and so on) make stuff that on paper smokes the major manufacturers. No experience with those though.
