mammynun 14 Posted December 4, 2010 Report Share Posted December 4, 2010 I took some video of my new PMR-30, and took my S12 along as well. Good thing, as the PMR-30/CCI .22WMR "blew up" on the 3rd mag.... I caught it on HD video, but I wish I had been shooting slo mo. Anyways. When I watched the S12 video, I was surprised to see that the ejected shell is smacked by the charging handle on it's way back forward. Every. Time. Other than accelerated wear of the finish on the CH, it hasn't been a problem and I don't think it will ever become one. It fires Federal w/o a problem; in fact, that's what I was shooting in the videos. The gun is self-converted: Polished internals Vltor stock adaptor. MOE with 3/4" riser Chaos Quad w/HK MD Arms V-Plug (pos #3 for slugs/buck/high brass, pos#5 for low brass/value pack) Wolff 18 1/2 lb variable rate 1911 spring http://www.brownells...R_SPRING_18_1_2_ I wonder if the spring has anything to do with it? Subjectively, the gun feels "smoother" with it when compared to the OEM spring... I changed the spring in an attempt to get the V-Plug more in the center of it's adjustment range, but I missed the mark. My next order will include 14 lb and a 16 1/2 lb springs. Here's the videos... http://www.youtube.com/watch?v=2ZbMj-hF7XY http://www.youtube.com/watch?v=bn04V4c0sjs http://www.youtube.com/watch?v=YeMY85j5j20 Quote Link to post Share on other sites
Gunfanatic 221 Posted December 4, 2010 Report Share Posted December 4, 2010 Looks like it is getting just enough gas to cycle those light loads. Quote Link to post Share on other sites
zenman223 460 Posted December 4, 2010 Report Share Posted December 4, 2010 what you mean the pmr-30 blew up? wheres the vid for that? Quote Link to post Share on other sites
dvdamurdoc 4 Posted December 4, 2010 Report Share Posted December 4, 2010 Huh, I've always suspected that mine does something like that, it just didn't make much sense to me why it would throw the shells forward. Quote Link to post Share on other sites
YOT 3,743 Posted December 4, 2010 Report Share Posted December 4, 2010 The last video shows that you are slapping the trigger. OK with a shotgun, but poor practice for accuaracy. Just pointing it out. Quote Link to post Share on other sites
mammynun 14 Posted December 4, 2010 Author Report Share Posted December 4, 2010 what you mean the pmr-30 blew up? wheres the vid for that? "blew up" is a tad bit strong... knocked off the slide stop spring and the little plastic slide stop tap. http://www.youtube.com/watch?v=iYzS5L0rVCE Quote Link to post Share on other sites

Just pointing it out. Slo mo reveals a lot! In my defense, I will say that (especially) during the slo mo I was going as fast as possible in order to keep the length of the videos managable....

justinmcmillion 77 Posted December 4, 2010 Report Share Posted December 4, 2010 I have the Galil style charging handle and after filming in slo mo I realized it will actually cause a failure when using cheap-o ammo, when using any decent ammo my gun runs flawless http://www.youtube.com/watch?v=QB1o2isrCDI Quote Link to post Share on other sites
YOT 3,743 Posted December 4, 2010 Report Share Posted December 4, 2010 I've read in these forums that the shell is ejected forward (x)feet @ 2 o'clock. Now I understand why. I understand why it doesn't eject forward with full power rounds too. Quote Link to post Share on other sites

I understand why it doesn't eject forward with full power rounds too. At 2:45 in my video I use 3" Mag Nitro Turkey's and they eject more to the side Full power round give the system more gas and work the action faster than light bulk pack loads. This causes the gun kick out the full power rounds harder making them fly out to the right more. The reason the light loads are hitting the charging handle is because the system is getting just enough gas to cycle, them making them dribble out the side and get thrown forward when charging handle comes forward and hits them.

evlblkwpnz 3,418 Posted December 6, 2010 Report Share Posted December 6, 2010 Nice footage. Hopefully the 'overgassed preachers' won't come in here telling you that your ports are too large It is befuddling how many people think that the carrier is to never touch the trunnion during operation. Mine pitches the hulls consistently at 2:00 from 5-8 feet away. Federal Multi-purpose bulk and Winchester Universal bulk. Quote Link to post Share on other sites
PYRO 44 Posted December 6, 2010 Report Share Posted December 6, 2010 Got the same bag in tan,,,,along with the MD20 in the center pocket, 12 round drums fit perfect in the two other pockets. Interesting vid, thanks for sharing. After moving the changing handle to the left side on my gun, some of the low power ammo I shoot ends up about 3' to my side and slightly behind me.

Interesting vid, thanks for sharing. After moving the changing handle to the left side on my gun, some of the low power ammo I shoot ends up about 3' to my side and slightly behind me. After reading through this thread, i was wondering if moving the handle to the left side would have any negative effects. I didn't know if it was a design feature to use the handle as a shell deflector such as that on a Ar-15. Im guessing nothing major, other then the low brass rounds ejecting more like falling out 2-4 o'clock. Doesn't seem to be a big issue right? edited for spelling and grammar .

PYRO 44 Posted December 7, 2010 Report Share Posted December 7, 2010 No negative effects that I know of, everything functions as it should. For me, it feels a lot more natural having the charging handle on the left side and not having to remove my right hand from the grip next to the trigger (without reaching over the top of the gun or turn it on it's side).
