    Does anyone use set triggers for hunting? What is their application?

    This is what the CZ website states: http://cz-usa.com/news/the-cz-single-set-trigger-system/

    The CZ Single Set Trigger System
    A lifetime of hunting will expose you to a multitude of situations. You will be presented with fleeting opportunities that require a quick shot and when hunting dangerous game you must be prepared for the life or death shot to stop a charge. On the other hand, most shots will give you the opportunity to shoot from a more stable position such as a rest, shooting sticks or a practiced kneeling or prone position. The CZ single set trigger (SST) system featured on 453, 527 and 550 models provides the shooter with the options to effectively handle any shooting situation they are presented with.


    The SST allows for both a standard hunting trigger and a light target trigger in the same rifle. By operating the rifle in the same manner as any other bolt-action, the trigger is in the “standard” mode with the heavier of the two trigger pulls. By simply pushing the trigger forward until it “clicks” the crisp and light target trigger mode is set.The standard trigger is adjustable for weight, creep and over-travel. The set trigger function is only adjustable for weight, but always breaks like glass. Many shooters will tell you that the single set trigger is a better aid to accuracy than a thousand dollar scope.


    CZ SST “Perfect Pull” Trigger Adjustment

    Tools required: 6mm wrench, 7mm wrench, one very small and one large common flathead screwdriver
    “A” (standard trigger pull weight), “B” (creep), “C” (over-travel) and “D” (Set trigger pull weight).

    [​IMG]



      • Make sure magazine and chamber are empty.
      • Remove the stock from the barreled action.
      • Cock the rifle then, adjust screw “B” in until it fires, back off ¼ turn.
      • Loosen locking nut and remove screw “C” to allow easy access to screw “A”
      • Adjust screw “A” to desired poundage and tighten the lock nut (ensuring that the screw position does not change).
      • Replace screw “C”, turn it all the way in then back it out while pulling trigger until fires, then back out an additional ¼ turn, then tighten the lock nut for screw “C” down (ensuring that the screw position does not change).

    Set Trigger Adjustment and Operation
    To adjust the set trigger weight, adjust screw “D” in to lighten and out to make heavier. If you prefer to completely disable the set function, turn screw “D” all the way in until the rifle fires, then back off 1/4 turn.
    An activated set-trigger is very sensitive to shock and during handling could unintentionally discharge if the set trigger is adjusted with too little travel. The safety of the SST adjustment can be checked with the rifle unloaded by repeated opening and closing of the bolt combined with moving of the safety to its “ON” and “OFF” positions in both set and unset modes. If the set trigger adjustment (engagement screw “D”) is too light, it will go off when doing this. In this case, add more travel to the set trigger adjustment until it does not simultaneously go off. (DISCLAIMER: Do not attempt trigger adjustments unless you are confident in your ability to follow instructions for adjustments and safe operation.)
    For safety, activate the set-trigger only after the rifle is loaded and when in position for the shot with safety in the off position. Do not carry your rifle with an activated set-trigger! If you have activated the set-trigger and you do not immediately take the shot, keep your firearm pointed in a safe direction and with the safety on, squeeze the trigger.
    This process will get you very close to the best trigger pull possible with only slight adjustments needed, if any, to get it to the “Perfect Pull” for you.

    Thanks, I did read that and it seems to suggest it is good for target shooting. I was also imaging using it for a long shot on a goat for example but didn't know if that is at all practical.

    I've used the single set system a number of times. For a fleeting opportunity, you just ignore it. For a longer shot from a rest, use it for maximal accuracy.

    I'm a fan.

    This is bang on !
    I have a few rifles with double set (2) 270, 3006, (3)9.3x62, and a Bruno 375 with a single set. I really really like them. Some folks dislike double set triggers saying that its too complicated. I have never found it so. I have converted a few of my hunting partners over the years. My advise is to try it !

    Regards
    Pat

    Pheroze, I currently only have one on my CZ 527 varmint in 223. It works well using the set trigger on prairie dogs. When I call coyotes though I don't set it and it works well too.

    It's great for load testing too.

    I don't think I'd want it on a DG heavy rifle. JMO

    Thanks guys. The 308 NM I am building has one (ZKK-600). I am quite interested to see what it is like.

    Very practical for a long shot and especially down prone. @BRICKBURN shot his Oribi in this manner as I recall and really had good things to say about the CZ set trigger.

    I haven't used mine much and for nothing other than target practice. I've found that I'm not any better of a shot with it than without it. I attribute this to a lack.of practice with it and not that the trigger itself can't help to improve accuracy.

    Had a CZ once with the single set trigger, and I'm not a big fan.

    Using different settings for different types of shots means I have to think more than I am often capable of, in the circumstances in which I have to take a quick shot.

    Much better, I find, is to have your trigger adjusted so that you can take a shot without unnecessarily moving the gun, while not scaring the daylights out of you when you touch the thing and it goes off. I've found something between what you get on an off-the-shelf rifle and the single set works in all conditions and allows you to practice easily and consistently for all conditions.

    Pheroze, it might depend on what type of trigger you have. If your rifle sports a short "pull" 2.5 to 3 lb trigger you probably won't benefit from a set trigger. If on the other hand your rifle's trigger has a long and or hard "pull 7 or 8 lb trigger than a set trigger is of great benefit. I have and shoot rifles with both types of triggers. You just have to remember which type you are shooting at the moment.

    Some like, some don't.

    Any longer shot and anything I have some time before the shot I use it.

    I also like my "normal" triggers set at three pounds. :)

    The closer the hunting resembles target shooting, the more purpose a set trigger has.

    I had trigger work done on my CZ 550 American 6.5x55. Unset it is 3lbs and very nice. Set is 12 ounces. Since the rifle is almost exclusively used from a deer stand I have plenty of time to set the trigger. I like the feature and use it.

    I have an old Brno zkw465 22h with double set triggers. I like it. Without the set trigger the break is not great.
    Great for shooting birds, geese, crocs and otters that cause problems at the fish farm.
    I disabled the single set trigger on my cz 416rigby as I did not feel it necessary. Also once disabled, the trigger break improved significantly and is now light enough to be just right for me.

    I'm not a fan of the set triggers. A lot of the muzzleloaders I own have the double triggers. Regardless if the regular pull is 3 pounds or 6, the set trigger is just too light. I feel if I look at it wrong it's going to go off. :confused:

    I have double set triggers on a 318 W-R and I do like them on this rifle. Having said this I would never want them on large bore rifle. I have no problem using the 318 for hunting and have taken three hogs and five plains game animals with this rifle. I do not think I would go out of my way to look for another rifle with double set triggers but it would not deter me from buying an old rifle that had them. WR 318-6.jpg

    I really don't like set triggers either. I would rather have a crisp 2.5 - 3.0 pound trigger pull. My Super Grade 70 Winchester trigger is about perfect.

    I have a Mannlicher-Schoenauer with DST that is almost impossible to fire without setting. The front trigger pull is approximately 11 pounds not set but, 8 oz. when set. So yes, I have to always use the set trigger when using that particular rifle.

    The only rifle I've ever had with a set trigger was a lovely Mauser 98 (a very early, J-bore Mauser, wonderfully done up). I didn't care for the set trigger and only used it once or twice (on the range...in the field, my longest shot was maybe 75 yards).
