HorizonT_s Posted October 12, 2018 Share Posted October 12, 2018 I just picked up a Shadow 2 and bought a 11.5 Hammer Spring for CGW as well as the extd firing pin and reduced firing pin spring. Are there any concerns of light strikes with this combo? I currently use blazer brass ammo which has cci primers which i have read are harder then most.

HI5-O Posted October 12, 2018 Share Posted October 12, 2018 I have the same set up but use Winchester primers. The S1050 allows me to control the seating depth of the primers so I have not experienced “light strikes” or “high primers. The CCI small pistol primers was having a harder time to seat deeper and had a handful that ended up sideways in the primer pocket. I use the CCI sp primers for my PCC loads.

HorizonT_s Posted October 12, 2018 Author Share Posted October 12, 2018 I don't reload yet that is my next step. I currently use off the shelf ammo and according to Blazer Brass website they use the CCI Primers. Link to comment Share on other sites More sharing options...
HI5-O Posted October 12, 2018 Share Posted October 12, 2018 Try a box or two and see. If you have problems, switch out the hammer spring to 13 and use it up. Probably won’t be able to feel the difference between the 11and 13 under match conditions. Link to comment Share on other sites More sharing options...
George16 Posted October 12, 2018 Share Posted October 12, 2018 I’m using the same hammer spring setup from CGW on my shadow 2 and haven’t had any light strikes with factory ammo. Heck, I even used CCI primers for my reloads for testing the hammer springs (8.5, 11.5 & 13#) I have on hand and the only time I had light strikes was when I used the 8.5# spring. However, I mainly use Winchester primers for my competition loads along with the 11.5# spring and reduced power firing pin spring and extended firing pin.

tbarker13 Posted October 12, 2018 Share Posted October 12, 2018 When I use the 11.5 lb hammer spring, I get light strikes too often to use in matches with win primers. I need to try seating the primers a little deeper. But for now, I use the 13lb spring, or the 11.5 with federals. Link to comment Share on other sites More sharing options...

busdriver Posted October 13, 2018 Share Posted October 13, 2018 I have the same set up, and it fires win small rifle primers just fine. Link to comment Share on other sites More sharing options...

I'm also leaving open the possibility that I could be running through a batch of suspect primers. These all came from the same lot. I just picked up some new Win primers that I'm going to try. As well as some Remingtons. Most of the other S2 users that I've talked to don't have this same problem. But for me, the light strikes happen anywhere from 1-5 out of 100 when I'm practicing.

RocketRyan Posted October 13, 2018 Share Posted October 13, 2018 It is very odd that this combo would not work. The 11.5 with CCI and WIN has been great for me. Do you have a another 11.5 or extended firing pin spring to try out? Could be an off weight spring. Link to comment Share on other sites More sharing options...

CCI primers would not ignite about 20% of the time. I use Winchester primers with no issue... only a handful of failures in 50k+ rounds Link to comment Share on other sites More sharing options...

Have you checked that you're firing pin is not worn? Earlier this year i noticed my failure rate with Win primers was going up, replaced my firing pin and the failure rate went back down to nearly 0. Bottom pin had about 20k through it. Replaced it with a new pin (Top) There was only .004 difference in OAL...

tbarker13 Posted October 13, 2018 Share Posted October 13, 2018 Firing pin has 5-6k rounds on it. But I've had the problems since it was new. It must be the primers or the seating depth. Link to comment Share on other sites More sharing options...

tbarker13 Posted October 13, 2018 Share Posted October 13, 2018 Not really sure how to measure it. But I'm using a 1050 so I can tinker with it. Link to comment Share on other sites More sharing options...

You can use the bottom of your calipers to check the depth. I try to go five thousands below flush. Link to comment Share on other sites More sharing options...

Test it out. If you can't test it, then run factory main spring until you start reloading...then you can tailor your primer/spring combo to what yields best ignition and trigger feel for you.

It will if you have an extended firing pin and the extended firing pin spring. If not you will need to put the stock hammer spring in. Link to comment Share on other sites More sharing options...
HorizonT_s Posted October 13, 2018 Author Share Posted October 13, 2018 I did get the ext fp and reduced fp spring. Hopefully it will all be here earlier this week so I can check it out. Link to comment Share on other sites More sharing options...
Riley Posted October 14, 2018 Share Posted October 14, 2018 I’ve shot about 2,500rds using the 11.5lb Cajun hammer spring and stock fp, stock fp return spring, stock recoil spring. I’m loading WSPP in mixed brass. I had 3 light strikes at a class I took but the gun was hot and dirty. The rounds fired the second time so I lean toward not seating the primers enough. Shadow 2 converted to SAO. I tried the extended fp and reduced fp return spring and was getting primer swipe and had my only stove pipe jam with it in. So I took it out. I’m using the stock recoils spring so it’s not unlocking early. I think the extended pin and stock return spring may work better. I have the slightest concern, so I put the 13lb spring in for piece of mind. Although it’s noticeably different trigger weight, it’s still pretty good and I like the slightly heavier pull. The 11.5 was pretty light. I do have the Cajun reduced power trigger return spring in and that helps. With a very light polish as per the Professor Atlas guide. Next trip I’ll try some Blazer and Lawman factory since those are my backup rounds. and for classes that don’t allow reloaded ammo. For ease: 13lb hammer spring reduced power trigger return spring stock fp and fp return spring SAO trigger with removed disconnector Stock recoil spring Shoots fine with my reloads with WSPP Link to comment Share on other sites More sharing options...

HorizonT_s Posted December 7, 2018 Author Share Posted December 7, 2018 So I want to update on this. I have had zero issues with the 13lb spring. Last match I had one jam but I have zero clue to the cause I didn’t slow down to pay attention but no issues after that. I still need to put in the 11.5 spring to test but haven’t found time.

Doc1 Posted December 10, 2018 Share Posted December 10, 2018 I seat my primer depth between 0.005 to 0.010 below flush. Sometimes at 0.010 the primer is slightly smushed but still ignites without premature detonation. Link to comment Share on other sites More sharing options...
