Smitty79 Posted March 22, 2015 Share Posted March 22, 2015 I've shot about 10k CCI SPP and some Remington and Winchester. CCI SPP's seem to be creeping back up in price and I'm not finding them as easily as I used. to. Federal are either expensive or hard to find or both.What do all of you think of Magtech and S&B SPP's? How do they compare in hardness? I have my Shadow with an 11.5# main spring. Goes bang 100% on CCI. I don't want to go harder than that. I've heard Magtech may be a touch softer than CCI. Will Magtech and S&B likely go "bang" with my current set up? Any chance they will work with an 8.5# spring? Link to comment Share on other sites More sharing options...
bthoefer Posted March 22, 2015 Share Posted March 22, 2015 I have an 11.5# spring in my SP-01. With Cajun gun works extended firing pin I haven't had any issues with the couple 100 rounds of magtech. Gun is 100% on CCI also. Link to comment Share on other sites More sharing options...
sonja55 Posted March 22, 2015 Share Posted March 22, 2015 With 8.5 LB spring and Extended firing pin, my 2 Shadows will reliably fire Federal primed ammunition only Link to comment Share on other sites More sharing options...

sclagg Posted March 23, 2015 Share Posted March 23, 2015 We've tested both the 8.5 and the 11.5... in our cz's 8.5 Fed's only! 11.5 (meets the 5# ipsc trigger pull rule) ran great with Win / CCI / Fed duh A couple of failures with S&B... one is all it takes for me Get a few and try... it's the only way to really know.

hangin Posted March 23, 2015 Share Posted March 23, 2015 I did some testing with primers and mainsprings about three weeks ago. I'm shooting a SP01 and a 75B both with CGW extended firing pins, CZ custom hammers and polished everything. The results were the same with both pistols. #8.5 mainspring CCI: light strike every time would ignite on the second hit Wolf/ WPA: about 90% light strike would ignite on the second hit. All first round ignitions came form being fired in double action. Federal: 100 % ignition in both pistols. #11.5 mainspring CCI, Wolf/WPA, Federal: All fire first strike and have good looking firing pin indents. I haven't tested any other primers or heavier mainsprings and I have about 10k federal primers on hand and If I had to switch to my CCI primers I Know my pistols are reliable with the 11.5# mainspring. Also I was getting some slight cratering with my 165 grain and Titegroup loads and deep firing pin indents, so I think with the 13# mainspring I run the chance of piercing the primer.

brisix Posted March 23, 2015 Share Posted March 23, 2015 I did not have success with S&B and the 11.5 lbs hammer spring, 6 light strikes in 35 rounds. Link to comment Share on other sites More sharing options...
