Brass deformation???

[G.T.]

Hi to all! Well, this little problem amounted to about 200 rounds going down range for very little gain, but, I think that Vlim, Rick and Dwight ( he posted a thread about this some time ago?)are spot on!!! ... This morning back to the range, and as a last ditch effort, switched out extractors...., and boom... 100% through 22 rounds.. another issue cropped up and stopped my fun, but the unit was doing everything perfect..... Now, the original extractor looks like the poster child for excellent extractors, clean and sharp.. but as Rick said, sharp might not be what we think it is??? ... Also, as an attempt to improve recoil energy, I used 124 grain ball, and that seems to be a good thing as well...
Now for the bad, I have one more drum of the current 15 going to NUMRICH to complete, as I held them back in lieu of an improvement, and I think that will happen.. But, I am as sick as a desert dog right now with a respiratory flu that has kicked all of me, especially my A**! ... So, sorry to say, I will be down and out for about a week as I try to recover from this creeping crud! Keep trying and testing and learning, I will be back as soon as I can be... Thanks again to all, and best to all as well, til....lat'r...GT...til....lat'r....GT

I always thought that when the theoretical and the actuals kinda agreed, I rested a little better for a while. When the actuals and theoreticals did not match up, it was always a pondering moment.

It would be interesting if any differences show up in the two extractors. Relative sharpness(wear characteristic, relative bite?), shaping of the edge, extension of the nose downwards, spring tensions/compressions, stuff. Some of the issues with me is the particular environment the part is working in, has some weight in the variables assigned for solution.

Of course after due time on the couch perhaps.

I guess the 'whys' always have had a calling here, can be good or bad I reckon, but tis the way it is here.

Maybe after some time, some Tex-Mex would be in order.....

Hi to all.... well after a month of, "under the weather" and several more trips to the range... here's what I learned... An excellent looking extractor, doesn't mean a great working extractor!... .... Now remember this gun works flawlessly on a regular 8 round mag, but the drums bring out the hidden weakness that may be hiding in your Luger! And this case was no different.. as I was improving bullet flow in the test drum, my extractor was wearing microscopically to offset any noticeable improvement?... In short no change, just very random jams, and marred brass???? So, in a last ditch toss crap at the problem effort! I changed out the extractor with another byf I happen to have along... and Walla! It worked 100% (3 X 32 with no problems) ..... But still marks on the brass case mouth?? ... So I took the ejector, and followed Dwight's instruction, and removed about three degrees from the front, so the tip of the ejector hits the lower middle part of the case head... Walla! That problem disappeared as well?..... ... more as I learn it! Best to all, til....lat'r.....GT...

I'm curious, G.T. Did you get guidance from Dwight by PM, or do you have us mixed up?!

Glad to hear you're among the fast and furious again.

Hi David! I was informed verbally and second hand about the ejector modification?......... I was told the work was performed by Dwight?.. Dwight has certainly made his fair share of contributions on the forum, and is greatly appreciated! Soooo, I could have heard it wrong, or just got it wrong, but I certainly want credit to go where credit is due, and if you're the member that did the pilot work on the modification, then my hat is tipped just as far as before, but for you this time! The results were great! I was considering cutting an small arc for relief, and see what happens there?.. Best to you David, and thanks... til.....lat'r.......GT.....

BTW, Hi David, I just now looked back and read your post that states the exact modification that I performed above? But, I never read your post up until right now, as I was not in the best of health and was away for awhile... I see where some confusion might result... Either way, you guys think alike and the problem went away! Thanks again, til...lat'r...GT
