    I just had the thought occur to me that whilst putting XXX shots of a given carry load through an automatic is accepted practice to ensure reliability that I've never thought of or heard of someone doing the same for a revolver.

    In fact I must admit I've not fired a single round of my 44spl carry load through the barrel of my revolver.

    What are you guts thoughts on this. Should ammunition be tested in a revolver too

    I think you should shoot it to see what kind of groups you get with it. As for reliability, this is a non-issue in a revolver IMO.

    Most definitely; it should be tested.

    How do you even know where the bullets go when they come out of your gun, if you haven't tried it?

    I say at least 50 rounds, but would prefer 100+. If you can get through all 100 rounds with zero failures, the theoretical failure rate is less than 1%.

    I've never fired carry ammo through my revolver to test reliability or accuracy. I'm not worried about jamming, because its a revolver. Won't have that problem unless I double-clutch it. I'm also not worried about grouping, because the overwhelming likelihood is that I would have to use it up close and under circumstances where I wouldn't get to aim properly anyway.

    I have fired carry ammo through my revolver to get familiar with the recoil and to test expansion in water-filled jugs.

    LOL double clutch!

    That's so true though.

    I plan on shooting a few rounds over my chrony to verify I'm getting what I paid for. I'm not concerned with accuracy though as I'm a firm believer of when that front sight is somewhere between the neck and belt buckle the trigger is getting pulled

    I absolutely test my carry ammo in my defensive revolver. It's good to know where they hit, and at varying distances. It's good to know exactly how they feel, recoil-wise. (I'm pretty sure that's not a word.) And it gives me the warm fuzzies to KNOW that it will work. After all, what if the ammo manufacturer put bad primers in the ammo? I've never heard of that happening, but if I have to find out, I want to find out on the shooting range. :p

    I usually do to verify proper primer ignition.

    I do test my carry ammo in my revolvers, but not nearly to the same extent as semi autos. A cylinder full or 4 do it for me, and I also "shoot off" older crudier ammo as it ages. Here are some good reasons to test, even in a revolver:

    1. Spent case extraction. I recall Winchester Super X .357 Magnum would not cleanly eject from my Taurus 66 (all other brands would). The cases could only be removed with the help of a screw driver and a small rubber mallet. That was annoying enough at the range; I imagine it would be a little more so in a fight.

    2. Ignition reliability. Theoretically, a particular revolver may have enough energy in it's lock work to ignite one brand of primer, but not another.

    3. Bullet/case separation. This is more important in flyweight revolvers under 20 oz, but I still do quick check on heavier guns as well. I did quite extensive testing on my S&W 642, by loading 4 chambers with my chosen carry load then firing a single, less costly round out of the 5th chamber, repeating about a half dozen times. Then I measure each of the other 4 rounds for bullet separation (I found very little in the 135 grn Speer Gold Dot, 158 Remington LSWCHP by the way). I did this several times over with various batches of 4.

    4. POA vs POI. Self explanatory.

    jad0110 beat me to the reasons.

    I'm not as hung up on revolver round count as I am with autos, but I like at least a box through my revolvers before I trust the gun/ammo/shooter combination.

    YMMV.

    I say some testing is needed. I have had some ammo that was rather difficult to eject after shooting.

    Would I test fire my carry ammo ~ absolutely. Simply because I want to know the recoil and time it takes me to re-acquire the target for follow up shots. Its a given that the more familiar you are with a weapons system, the more confident you will be and that equates to how effective you are.

    When most LEOs carried revolvers as a primary weapon, it was common to see full house .357s as carry ammo and a lot of wad-cutters shot for practice. There was a big difference in the report of the weapon and recoil. It made sense to require a qualification with duty ammo.

    Today, the semi-auto practice rounds are close to their duty counter-part with the exception of bullet configuration. Your not going to see a lot of difference.

    I would not worry as much about revolver reliability as other factors involved with the ballistics of the round.

    I agree. I don't think you need to necessarily test a large number (100-200+) like many people do with their semi-autos, but firing at least a few cylinders full, both in slow aimed fire to see general accuracy and recoil, plus rapid fire to see that it goes smoothly and groups o.k. (hits near center mass) is a really good idea. The last thing you need when in a defensive situation would be for your ammo to hit several inches low at even close distances (not a problem if the attacker is right on top of you, but I could see needing to fire at 5 or 7 yards in certain rare situations) or that it is the one ammo whose primers are too hard for your revolver. Then there's possible issues with extraction if you carry a reload and need it for some reason, etc.

    Admittedly, these are all very unlikely scenarios with a revolver in a "normal" self-/home-defense scenario, where it's close and only takes a few shots, if any. However, I figure it's worth the price of a box or so of premium ammo to know with "reasonable certainty" that these aren't likely going to be problems just in case the unexpected does occur. JMHO

    The only guns I have ever had seize up, and refuse to work at all (with the tools available at the range), were revolvers. Had some cowboy loads seize up a 44-40 once fired due to soft brass that expanded the rim thickness. Test everything you cannot afford to have fail.

    I guess I've always test fired carry ammo. Never needed to. Might have carried some for a while before I got around to testing it.

    I haven't had any WW 158gr lhp 38 ammo for a long time. If I get some more, I might figure the test firing I did 10 or 20 years ago still counts.

    Yes, I think you should. I have encountered sticky extraction with some brands in some revolvers.

    Revolvers need to be function tested with new ammo just like a semi-auto, the difference is what you are looking out for.

    >Point of impact versus point of aim at 3 and 10 yards
    >Clean extraction an good primer strikes
    >Fire off almost a full cylinder. Take the last unfired round, mark it, put it in another full cylinder, fire off all but that last round and check for the bullet being pulled out under recoil. Really it only needs to survive one cylinder full worth of recoil, but ideally it should be solid enough to survive more.

    Some basic ballistics test are also a good idea. Will the round punch through a 2x4? How does it expand in water, or ideally ballistic media?

    How can you know the point of impact? How can you know how the recoil will be? How can you know if there are any hangups when reloading? How can you know if the primers are too hard for your pin?

    Carrying ammo you don't shoot just strikes me as asking for trouble.

    ditto what jad said. Primer sensitivity, overall length, bullet crimp

    I'd rather not rely on getting a lucky shot. So I test POA vs POI, extraction, reliable ignition.

    I always shoot a few rounds through a revolver. I am rarely concerned with groups but I am concerned about point of impact vs point of aim.

    I am in the minority on this subject, and well aware of it

    I don't distinguish between "carry ammo" and any "other" ammo, but I want to know the gun is reliable, and I am more inclined to rely on caliber, than specific loading (and factory centerfire cartridge failures have been about as rare as hen's teeth for me, be it whitebox or boutique). I don't often carry as hefty as many do, but if if/when I do feel the need, I just get a bigger gun out of the safe, rather than push it up with hotter loads of same caliber. "bring enough gun" for the load, control the shot

    So I shoot minimum a couple hundred rounds out of any handgun I would even think about carrying, right up front (preferably a mix of brands & loads)... and generally a few hundred more (mixed loads, but nothing unique), before I actually would swap out with something I have been carrying. Many here have said 25 rounds will do, and that's ok by me, but not ok for me, that's all.

    Odd attitude for a guy who leads a dull, quiet lifestyle, and doesn't even bother with carrying reloads much less a BUG , but I figure it's not the "probability", it's the consequences. I need reason to believe, beyond my high level of faith in revolver reliability (which is pretty doggone high).
    Threat assessment (right or wrong, win, lose, or draw) determines what gun I carry, not what load. But whatever I carry has gone bang a whole lot first, no fail, whatever it is.

    My "most likely to be carried" revolvers have been with me for decades, and I know what the POA/POI is, and I consider this to be an issue of major importance. When a lethal attack is under way, a “somewhere” hit on the attacker doesn’t always bring the desired result. If the sights weren’t right in the first place something was changed years ago. I don't consider reliability to be an issue, and they are all well broken in. Most of them were purchased used in the first place, so someone else got to go to the expense of doing the "breaking." :evil:

    All of my pistols and revolver guns I consider a carry or hunting gun or both. I reload and try to shoot all the reloads in each gun with in 6 mths, not including the what if and try that loads. We carry this out in the winter and it is a hobby for the wife and I with 5 differnt calibers 10 differnt hand guns. We both have carry permits and do exercise the right and practice regulary.

    just honestly curious here, not contentious, Old Fuff
    (you being amongst those known to carry a snubbie every once in a while, fitzed or unfitzed, as the case may be, and been doing it for way more than just a few years)

    We hear a lot about the critical difference in POA vs. POI
    In your hand, your gun (pick any example you personally like for "most likely to be carried")
    How much difference would you say POI varies from POA (how much you compensate for on POA), for the "worst" of your own top three picks for your own carry.. (no need to even name specific model).. include any disparity of load example for anything you might choose to shoot thru that gun choice, be it range play, or seriously concerned about self, or all of the above.

    at 7 yards ?
    at 15 yards ?
    at 21 yards ?
    (give or take fair approximations of distances perfectly acceptable, of course)

    I have heard of some pretty dramatic differences, just don't myself shoot varied enough loads.. or I just don't shoot worth snot, maybe (never said any different)

    Just looking for results from someone who has been there and done all that, no kidding, I am a believer, not a skeptic
    POA vs POI sure does matters, most certainly does
    (mama raised a fool, not an idiot child)

    I've had many snubs over the years. Had a third gen Detective special that shot 6-8" high at 15 yards with my prefered loads 135gr golddots and 158gr LSWCHP, I got some 110gr silvertips and this brought it down to only being 3-4" high. I still wasn't real happy with this, and while I felt comfortable carrying it, I was given an opportunity to trade for a DS-II and jumped on it. It shoots my 135gr golddots right on top of the front sight blade at 15-25 yards as it should be.
    This kind of performance is typical of all my pocket guns that I've ended up keeping.
