I've got a M-617 revolver and I'd like to reduce the Double Action pull weight. With all the different brands of .22 LR ammo available which brands are known to be the most sensitive?--I'd like to reduce the pull to about 8 or 9 pounds but I also want the gun to go bang each time I pull the trigger. Suggestions most appreciated--thanks.

8 or 9 pounds should be more than enough impact to ignite any rimfire ammunition out there.

Federal has the best reputation for going off when struck. Remington has the worst. Winchester for having or accepting hard brass and requiring the heaviest hammerfall. I have a bunch of CCI, but its OK. Its just more expensive so I don't buy it.

More important than sensitive primers is the reputation for not even having priming compound in the case. That's were the Remington has gotten a bunch of bad press over recent years. Time was it was the best. It seems like you can cheapen stuff and destroy a good name. I still buy and like their center fire ammo.

Eley 10-X is pretty sensitive; don't ever remember getting a dud in thousands upon thousands rounds fired over many years. Kind of expensive, though.

Not necessarily more sensitive, but Ely has much better quality control than the bulk stuff bought at your local big box store. When you shoot at top levels of competition, any misfire is unacceptable.

Dick,
In my semi autos the Remington Golden has a ca 5+% igintion failure rate. The same ammo in my S&W 617 exhibits one ignition failure every 300 to 500 rounds. I have attributed this to a fragile priming compound.
In contrast the Federal bulk pack HV HP copper washed ammo which in my semi auto's provides a very low rate of ignition failures does the opposite in my 617.
You figure!

Groo here
Try Wolf match..
Around here about $4 a box in bulk this is real match stuff
and made on the same machines as the big boys .
It is lubed and a little sticky but shoots great in anything I have tried.

Agulia .22 ammo is modestly priced and is very reliable. Their ammo
boxes claim Eley priming is used. Pull a bullet from one and you will
notice that the case contains much more priming compound than US
brands of .22 ammo. I have fired lots of it and can't recall a single FTF.
Nasty smell but good ammo.

I use Aguilla SE SV ammo in my S&W Model 41 and an older K-22's. Excellent ammo.
When I shot bullseye pistol Imy Walther GSP ran well on a diet of CCI SV but when I switched to a Pardini SP I found that Wolf MT/SKJagd PM provided the best reliability.

How do you intend to lighten the trigger pull weight? There are different methods. Lightening the rebound spring will not effect the hammer energy to set off the primer but will lighten the trigger some. You can have a custom trigger job done, polishing and reshaping the trigger action with no spring changes at all. I also read something about using an ultralight replacement hammer with an extended firing pin. There are quite a few options to lighten the trigger which may or may not effect the hammer strike.

If your 617 is a frame mounted firing pin, your might also install a C&S extended firing pin, which is a little longer. If you do, check to see if the new firing pin hits the chamber rim before you dryfire it. Of course if you use snap caps, it will not matter.

my fav. .22lr ammo that i use in my 1911-22 is:
1. CCI stinger hv
2. Remington Thunderbolt.

both are very smooth and highly accurate.

when i purchase a m&p15-22 i plan to use CCI AR-Tactical. seen very good reviews.

I would stay away stay away from rem ammo on the 15-22. Cci and federal have worked wonders.

took my 15-22 out again to the range yesterday. 100 rounds of cci ar-tactical,100 rounds of remington thunderbolt. the group size (average of 4 25 rounds magazine targets):

CCI AR-Tactical: 3.25 inches at 50 yards
Remington T-Bolt: 3.8 inches at 50 yards

tightest single 25 rounds targets:
CCI : 2.2 inches
Remington: 3.3 inches

winner,winner ar-tactical dinner. cci ar-tactical is the exclusive ammo for my 15-22.

what do you think of mini-mags for an 15-22?

Haven't shot them yet but you can't go wrong with cci products
