RePete Posted December 15, 2017 Share Posted December 15, 2017 Rob: Measure the diameter and lengthof the RCBS pin and we can compare. It may be too long and/or too thick. Link to comment Share on other sites More sharing options...
RePete Posted December 15, 2017 Share Posted December 15, 2017 I measured the Lyman pin and the OAL is 0.545" and the diameter is 0.058". Link to comment Share on other sites More sharing options...

slavex Posted December 16, 2017 Author Share Posted December 16, 2017 I'd think longer would be better? Link to comment Share on other sites More sharing options...
RePete Posted December 16, 2017 Share Posted December 16, 2017 Not with the spring loaded Dillon die. Link to comment Share on other sites More sharing options...
slavex Posted December 19, 2017 Author Share Posted December 19, 2017 so while I'm waiting for the Lyman pins to show up I decided to try something else today. I hit a really bad batch of brass for pull backs, even with the Redding dies. So I threw a Dillon 40 S&W die on the machine and the problem all but vanished. after 22,000 brass processed today I only had maybe 20 pullbacks after the swap. Just for giggles I threw the Redding die back in, and almost immediately had pullbacks again. Put a new decapping rod in it, still had them, put the 40 die back in, problem gone. Concusion? I hate decapping brass. Link to comment Share on other sites More sharing options...
cvincent Posted December 31, 2017 Share Posted December 31, 2017 I don’t have any primer pull back problems with 223. I gotta say though, loading 9mm is the worst. It has primer pull back, crimped pockets, run the mark 7 at a 5 clutch, and if a piece of brass doesn’t get as much lube as the others it will stop. On the other hand 40 cal runs all day long at a 2 clutch and no stoppages ever, Unless aPiece of 357 sig gets in there.

sparky2008 Posted September 13, 2018 Share Posted September 13, 2018 You're spot on with the spring loaded Dillon dies. They are better at preventing primer pullback than any other decapping die I've used. I don't know if this will work in your case but you can use an oversized Dillon resizing die as sort of a "universal" decapping die. With pistol brass, a 45 resize/decap die becomes a spring loaded decap-only die for smaller cartridges like 40, 9mm, 380 since the brass is smaller than the resizing ring. I don't work with rifle cartridges though so couldn't say whether any of the pistol dies would work without affecting the shape of the rifle brass. I imagine the center of the die may be too large for the necked cartridge or the die may not be deep enough. Link to comment Share on other sites More sharing options...
Tokarev Posted October 10, 2018 Share Posted October 10, 2018 Maybe try the universal decapper from Mighty Armory? Fast and Friendly Brass also has a rod that fits the Lee decapper. This rod takes the RCBS pins. FFB says this pin eliminates or drastically reduces issues with primer pull back.

slavex Posted October 17, 2018 Author Share Posted October 17, 2018 I've been running a Mighty Armory for awhile now, and loving it, still the odd pullback, but far far far less than I had before. Like maybe 2 or 3 in 10,000 brass Link to comment Share on other sites More sharing options...
