AT84S

[M4A3shooter]

is anyone having problem with 115 gn plated bullets in their CZ75 or AT84S? im not sure if its my magazine the problem or the rounds itself. Its not ejecting the empty case sometimes and most of the time the round gets kinked half way. I need help anyone with AT84S? or CZ75 or just reloading problem :banghead:

Sounds like the bullet nose

I had a similar issue with my 10mm witness. I bought some RNFP west coast copper plated bullets, but the gun did not like to cycle them flawlessly as all the factory rounds have done.

I reworked the rounds and made them a touch longer. Mine were catching on the case mouth at the top of the chamber (12:00 position) because the bullets looked to be seated too far at the suggested 1.250 length. I used the extractor to unseat them a bit and then reworked them to 1.265 or so. Hand cycling showed quite an improvement. They still fit in the magazine fine, and I have a tad more room to work with, but I was nervous since they were longer than the suggested specs.

They fed better, but my magazine was sticky that day (overcleaned, did not put any oil on follower when doing such, now fixed with an ever so light application of gun oil to the inside of the magazine, very sparingly, but noticeably less sticky when filling it up with 15 rounds) My witness still did not like the first two rounds out of the magazine that particular day. After that, they fed great.

However, when comparing the West Coast bullets to the American Eagle factory ammo, the nose of the bullets was 0.025 different wider on the American Eagle stuff. I guess these are called flat points, not round nose flat points, I'm not quite sure. The american eagles fed flawlessly and allowed the bullet to guide it at 12:00 position after hitting the ramp and going up instead of the case mouth catching.

So, now I have 400 bullets to sell, or load and be frustrated with. I'm lazy, I suspect I'll load them and keep tinkering so I can beat this one, but when I purchase more, I will go for more of a flat pointed bullet or SWC so a fatter nose is present that prevents the case mouth from contacting the 12:00 position in the chamber.

Hope this helps,

M4A3shooter,

All I shoot in my Witnesses are plated bullets from Berry's Manufacturing. They feed flawlessly. It sounds like you're having more of an ejection problem though, which would have nothing to do with the type of bullet you're loading. Make sure the extractor groove is clean under the extractor. If there is a buildup in that groove, the extractor can't get all the way into the rim of the case and have enough bite to pull it out.

If, on the other hand, you're talking about the round not feeding properly from the magazine to the chamber, then that's another issue. See below.

jeepmor,

Your problem is easily fixed by first polishing the feedramp and then polishing off the sharp edge of the chamber mouth of the barrel. This can be done with a Dremel tool, using a fine Cratex wheel of the right diameter and a light touch. I usually finish it off with a felt bullet shaped wheel and some Flitz metal polish. It only takes about five minutes to do a feedramp and chamber mouth and will cure the feeding problem. All my Witness pistols have been done this way and will feed any type of bullet I load in them.

Hope this helps.
