In what ammo brand/grains your semi automatics work best?

Other than some cheap, unknown brand of steel cased 9MM, and a Walther P22 that is a bit picky about rimfire ammo, my guns prety much run what ever I put in them.
My personal preference for SD ammo is Speer Gold Dot.
 
all of them. if they don't like certain types of ammo, I get rid of the gun... life's too short to maintain logs of what ammo I'm allowed to use in what guns.
 
In hat ammo brands/grains your semi automatics work best

Our pistols seem to like any rounds.
Except my Sister Sig Sauer .22 won't shoot anything but CCI Stingers and a few others. The gun we've been told by Gun smiths and others was chambered around that round.
The .380 barrel apparently fires everything without problems.
I don't shoot the steel cased stuff.
One of the reasons they chrome the bores as well as the barrels is the stuff is rough on the guns.
I have fired some and no problems but I don't ordinarily buy it.
I load my own usually.
Only problems in .22s in newer guns is the old wax/greased bullets some times, build up, in the chamber and chamber mouth causing malfunction.
My 9mm's like all ammo but the HiPower like NATO stuff a bit better, but not web of my hand.
I am not sure what you are looking for but mention the gun you intend to use and get a lot more pertinent answers.
 
About all I've ever fired in mine for factory ammo was Blazer Brass. 115 Grain FMJ in 9mm, and 230 FMJ in 45.

But mostly I shoot my reloads...pretty much the same.
 
I think of this question pertaining more to 1911s.

I believe most out-of-the-box 1911s work with just about any factory ammo out there. I'm thinking of Colt, springfield, Ruger as examples of these guns.

But I have heard that the upper echelon of guns such as Wilson or perhaps Nighthawk can be picky with ammo because of how tight and precise they are.

Talk exists of "break in" periods and I believe a gun should be thoroughly tested but reportedly it seems the higher priced ones need that so-called break in time more.
 
Generally speaking, I have found semi-autos to function their very best with the heaviest bullet weight commonly offered in each caliber- so long as it adheres to the OAL the cartridge was designed to function with.

230 grains for 45 ACP, 180 for 40 S&W and 124 for 9mm. This comes from about 25 years of procuring practice and duty ammo for a wide range of pistols.
 
I have the same ammo preferences as Sarge: 124 grain for 9mm Para, 180 grain for .40 S&W, and 230 grain for .45 ACP.

I do have a Walther P22 that requires high velocity .22LR to cycle reliably.

I have had issues with somewhat under-powered Eastern European 9mm Para ammo failing to cycle my Berettas.
 
I have found 22 semi-auto handguns to be a law unto themselves; there's no telling what two specimen of the same brand and model might prefer. 40 grain loads over 1150 fps seem to be the safest bet.

Federal Automatch, Federal bulk 36 grain HP and CCI Mini Mags have all shown good function in my guns. Winchester Super X if the others aren't available and I leave Remington on the shelf.
 
My Walther P99c will eat anything I feed it. I prefer 124g HST or Gold Dot for their exceptional performance. But the 147 are great too.
 
any ball ammo works fine in mine

all my semi autos function fine with any type of ball / fmj ammo I feed it

brass cased, steel cased, aluminum cased

;)
 
"...22 semi-auto handguns to be a law unto themselves..." Yep. And some are far more particular than others. Has nothing whatever to do with quality or price of the pistol or the ammo though. A Smith 41, for example, runs $1,369, MSRP. Every one of 'em will shoot and cycle the same ammo differently. Or not at all.
"...semi-autos to function their very best with the heaviest bullet..." Not applicable for all pistols. Lot of 'em will require changing the return spring for heavy for calibre bullets as well as a different spring for light bullets.
In any case, the brand, like the price, means nothing. If you're not reloading you have to try a box of as many brands as you can to find the ammo your firearm shoots best. In the case of a pistol, the ammo has to be accurate and cycle the action. What works in mine may or may not work in your's.
 
All my Glock, HK, SIG, and Springfield Armory (TRP) pistols have performed flawlessly with everything I have run through them with an exception of some Tula and Armscor primers. They needed to be smacked a couple more times. With the HK.
 
Other than my Cougar's dislike of all things Federal, 124 and 135 Gold Dot and Hornady for the 9's, 230 Golden Sabre's and Gold Dots for the 45. Also, I've bought a bit of the Sig JHP due to the price and everybody likes that, too.
 
My shield(s) 40&45 will eat anything I feed um.
No WWB its the only ammo Ive ever had malfunctions using so I wont buy it EVAH.

Pretty much anything. I've been using a lot of Blazer Brass lately due to availability and cost and it's been fine.

I do tend to avoid steel cased ammo, not because it won't work but because I find it doesn't expand as well as brass and especially in 45 ACP I get a lot of gas blowback into the pistol. When running a few hundred rounds of Tul Ammo I had issues where a lot was getting blown into the firing pin channel and actually caused issues with function.

I am intolerant. If there is any normal off-the-shelf ammunition the gun won't function with, I get rid of the gun.

The only exception is Winchester white box 32acp. I don't think any of my half-dozen or so 32acp automatics will function reliably with that stuff. I had a few boxes and ended up shooting most of it out of my 32 magnum revolvers to get rid of it. The brass reloaded okay, IIRC. They seem to have made a very poor choice of bullet shape.
 
If a gun has any sort of "plus" capacity magazine, I tend to go with lighter bullets.
Often, the spring has to be weaker in order to fit the additional round(s) into the tube, and lifting more rounds with a weaker spring isn't my idea of a good time.
 
Mine:

.45 acp
I only own one, a Tisas Zig1911A1, your standard USGI 1911. I've shot WWB, Freedom new manufactured (I got in on the gearhog deal!), and Blazer Brass. No problems with any, no problems with any mags (Mecgar 8 rd came with it, my brother's Chip McCormick, and a couple of Sarco "real cheap" mags). 230 gr FMJ.

9x19
I own a bunch of guns, the only issue I've come across was with WWB and UMC; were crappy, dirty, and had some failures.

There are a couple that I don't want to run hot loads through, since they are surplus and older; Blazer Brass seems to work well in these. Easy shooting load. 115 or 124 gr, FMJ
For my more modern doublestacks, everything runs, but they seem to like S&B and PPU 124 gr in particular; like they were designed with that round in mind. 115 or 124 gr FMJ for target and practice.

9x18
I have a few, these all shoot anything available with no percieved difference. Only concern I would have- the CZ 82 has polygonal rifling, I'd avoid shooting cast lead reloads (I don't have any, but would not do it). Have 94 gr from Brown Bear, Tula, Geco and Fiocchi brass. All of these guns also shot the Hornady and Silver Bear JHP without problems.

22lr
I have a High Standard Sport King, a S&W 22A, and a Ruger MkII.

I only shoot standard velocity ammo out of the High Standard.
The S&W seems to eat everything, as does the Ruger.
Occasional FTF with Remington Bucket of Bullets (the 1700 rd bucket), and same issue with Winchester value packs. ANYTHING that comes in bricks of 500, with 50 rd boxes, feeds great in all 3 (have shot Blazer, Aguila, Winchester, etc).
