phara Posted April 20, 2003 Share Posted April 20, 2003 I think we all agree that Federal makes the most sensitive pistol primers and I know that many times I have seen it said that Winchesters are the next most sensitive. Well I have had something happen that leads me to believe that Remington primers are actually more sensitive than Winchesters. I ran out of Federal so I put the factory main spring back in my 625 and set my hammer at 3 lbs (a 2 pound hammer tension will fire off Federals 100% of the time in my 625 and +4 pounds is what the factory sends us.). All I had were Remington primers and these all fired fine with my increased hammer tension setting. I shot about 1,000 of these without problems. When I started to run out of these I bought some Winchester primers and for a while I had a mixture of Winchester and Remington primers in my ammo box. I began to mix them up in my cylinders as well. I started to get misfires and guess what? Every single misfire was a Winchester primer while all the Remintons fired without a single misfire. What a surprise! Anyway, this may be something of interest to you all. Regards, Paul Link to comment Share on other sites More sharing options...

Davis Posted April 24, 2003 Share Posted April 24, 2003 I have had recurring failure to fires from the Brass colored Winchester primers. I didn't have the problem with the old Winchester Nickel colored primers. I rechecking the seating depth, and all. I even changed reloading presses. I then replaced the firing pin springs in my G20's and still had the problem. I was even having the FTF problem with my S&W 610 revolver. I thought " ok maybe just a bad batch" , but after going thru 2 new boxs of 1000 ea, and still having this intermitten problem, I gave up I went to CCI primers and haven't had a FTF with any of those. I'll stick with CCI or Federal's from now on. Link to comment Share on other sites More sharing options...
