Iggy42 Posted June 8, 2022 Share Posted June 8, 2022 Has anyone tried the Everglades or Black Dot 9mm Major Ammo in a Domina (the basic "blue" one, not the Xtreme) running MBX 170mm mags https://www.evergladesammo.com/9mm-major.html https://blackdotammunition-com.3dcartstores.com/9mm-MAJOR-124gr-br-100-ROUND-BAG-br-Competition-Specific-Ammunition-brREAD-DESCRIPTION-CAREFULLY-br-Not-for-use-in-standard-9mm-firearms-_p_18.html Seems like round nose is the preferred, but I am on a limited budget and very limited time so the option to roll my own is not available to me and these seem to be the only 9mm major I can find in stock. That said the Atlanta 147gr is also JHP.... I heard that the Tanfoglio's are not fond of JHP, but no one in the Tanfoglio sub forum is answering so I thought I would also ask here. It is something that I just need to have the barrel reamed, or is it something else. Trying to cost out my Open options and Tanfoglio's have always appealed to me. Yes I know the Czechmate is basically the same, but sourcing 170's looks to be an issue from what little I can find on them. Link to comment Share on other sites More sharing options...
darthdively Posted June 8, 2022 Share Posted June 8, 2022 I never had experience with that brand of ammo. But, I do have experience with a tanfo gold custom. if they are anything alike, avoid all jhp or flat nose, especially in mbx mags. Constant nose dive issues. I know you stated you dont have time to roll your own. Sorry i cannot think of a 9 major fmj producer at the moment. Link to comment Share on other sites More sharing options...

Yeah I am yet to find someone that does fmj in 9mm major, but the Black Dot is loaded to 1.16 and the Everglades is 1.145 which is fmj territory if I understand things correctly. I'm hoping that it addresses the nose dives associated with the Gold Teams. I think MBX made some design changes to as well, but I can't find answers to either sadly. I think Black Dot is using Montana Gold JHP which look rather RN Everglades I think uses their own "Round Nose" JHP Pretty sure I would need to have the chamber reamed, but again I can't find answers Link to comment Share on other sites More sharing options...
regor Posted June 8, 2022 Share Posted June 8, 2022 I can't give you a Tanfo specific answer but since they are very similar to CZs I can share my experience with the Czechmate. Tuning the CM mags to reliably run JHPs was a pain; it didn't matter if it was a cone JHP like Precision Delta, a rounded profile like the Everglades, or even a flat pointed coated lead bullet; all would snag on the front edge of the barrel ramp when running 170mm mags at full capacity. I even had issues occasionally with 140mm mags prior to tuning. With the CZ mags it can be addressed with careful tuning but RN bullets are considerably more forgiving; I was never able to get my 170s to run 100% with JHPs (maybe like 1/10 29+1 starts would cause a nose dive with JHPs) so I switched fully to RN bullets and haven't had any feeding issues since (closing in on 16k rounds of round nose through mine). I certainly would not recommend anyone shooting a Czechmate pursue JHP bullets. darthdively's comment makes me think the issue is similar with Tanfos.

So if I understand correctly the hollow part of the hollow point gets caught on the feed ramp when loading out to 9mm major lengths Link to comment Share on other sites More sharing options...

I never tried super short like 1.12 with Major, but I had some stuff loaded to around 1.14 that had the same issue. Link to comment Share on other sites More sharing options...
Iggy42 Posted June 10, 2022 Author Share Posted June 10, 2022 Does the issue with JHP only apply to 9mm major? And is 38 super and 38 super comp interchangeable? Link to comment Share on other sites More sharing options...
