EasyEJL Posted March 4, 2014 Report Share Posted March 4, 2014 I'll try to remember to at least get a couple of gun industry relevant ones up a day the next few days at least Quote Link to comment Share on other sites More sharing options...
Bones Posted March 31, 2014 Report Share Posted March 31, 2014 Yes, builds or anything else interesting. The idea is not to have to chase content all over the forum. It also eliminates asking if it's ok to post the info. Trying to make things easier Quote Link to comment Share on other sites More sharing options...
Bones Posted March 31, 2014 Report Share Posted March 31, 2014 I will try to make this short I have a DPMS G2 SASS i've shot three different rounds through it and all the rounds are cratering on the primers. It appears to me the whole where the firing pin comes through on the bolt is excessive and it's letting the metal of the firing pin come back and creating a crater. Any suggestions Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted March 31, 2014 Report Share Posted March 31, 2014 I know you said three different rounds, but are they commercial/off the shelf, or reloads? Just trying to get an idea of cartridge power. Cratering is usually a good sign of over pressure, but an enlarged firing pin hole or thin firing pin can also be the culprit. How does the tip of the firing pin look? Pictures are worth 1,000 words. Quote Link to comment Share on other sites More sharing options...
Bones Posted March 31, 2014 Report Share Posted March 31, 2014 The rounds are off-the-shelf HSM168 GR HP BT they are all store-bought i can't seem to send a picture I tried. I'm doing this off my cell phone I don't have a computer and shot three rounds from a Vietnam vet that he hand loaded they cratered also. Firing pin looks just great I rolled it on a glass counter it's not bent Quote Link to comment Share on other sites More sharing options...
Bones Posted March 31, 2014 Report Share Posted March 31, 2014 I just talk to tech-support at DPMS and he said there is nothing wrong with my gun. He said it supposed to do that I just don't think that's right I really want you to see a picture of this I have it in my phone and I can't seem to send it to you can I send it to you through Facebook Quote Link to comment Share on other sites More sharing options...

shibiwan Posted April 3, 2014 Report Share Posted April 3, 2014 (edited) Wow... those primers look cratered. Probably a hot load..... What kinda rounds are you putting in that thing? HSM? what else? PPU? (can hardly make out the headstamp) ADI (indonesian surplus?) Edited April 3, 2014 by shibiwan Quote Link to comment Share on other sites More sharing options...
Bones Posted April 3, 2014 Report Share Posted April 3, 2014 The top ones are handloads from a Vietnam vet they are a little hot the middle ones are 168 grain boattail hollow points made in Missoula Montana the bottom ones PPU their regular store-bought shells I don't know why I think there's something wrong with the bolt face where the firing pin comes through the bolt. The hole in the bolt for firing pin seems to be excessive Quote Link to comment Share on other sites More sharing options...

Bones Posted April 3, 2014 Report Share Posted April 3, 2014 This is the DPMS G2 SASS That craters primers. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted April 3, 2014 Report Share Posted April 3, 2014 This is the new pattern DPMS rifle ? Looks like primer material is flowing into firing pin hole , on cartridge ignition. Too much clearance in bolt face for firing pin ? This is a new beast from DPMS & who knows what or how they made it , to do what ever it does . There will be problems with some rifles from this new design , I would think, not sure you have a problem , if this is what they expect from this new design. And they say this in normal ? Top ones in the photo are hand loads ? He did a fine job of lacquering the primers . I would think the middle ones are hand loads ,because of the silver primers & lack of sealant , but I have seen some factory ammo with silver primers .
