selecw Posted March 14, 2016 Share Posted March 14, 2016 My 9mm Gold Team does not seem to like HPs. I am using 124gr Precision Delta and Xtreme, and have the same issue with both: as rounds are stripped from the mag by the slide moving forwards, they angle upwards at about 45%, and jam when the tip hits the roof off the barrel chamber. I have tried OAL of between 1.10 and 1.12 but this doesn't help. I can't go longer than 1.22 with HPs without experiencing increasingly stiff extraction. The problem occurs across all my mags, which are all fitted with Hennings extended pads and Grams kits. I don't seem to have the same problem with RN bullets, but have only tested about 50 so far, using a 1.140 OAL. Any theories or possible solutions? Thanks!!

selecw Posted March 14, 2016 Author Share Posted March 14, 2016 I only tested my theory with the 50 RN bullets I had on hand. I'd sooner know more before ordering several thousand ... Link to comment Share on other sites More sharing options...

I run Montana Gold JHPs in my Tanfo at 1.135" without any issues. Link to comment Share on other sites More sharing options...
selecw Posted March 14, 2016 Author Share Posted March 14, 2016 Yes, I tried lengths between 1.110 and 1.120. I can't go longer than 1.122 with hollow points without extraction getting harder and harder as the rounds contact the rifling By the time I get to 1.130 the slide won't retract as by that point I'm really jamming the rounds into the rifling. With RN bullets I can load significantly longer due to the difference in the bullet profile. Link to comment Share on other sites More sharing options...
kneelingatlas Posted March 14, 2016 Share Posted March 14, 2016 OK, makes sense now. I guess your options are ream the chamber or sell the HPs and buy some RN Link to comment Share on other sites More sharing options...
selecw Posted March 15, 2016 Author Share Posted March 15, 2016 I can use the 124s in my production gun, or IDPA, so no real issue there. I'd be interested if anyone out there has had a similar issue with HPs. Presumably a lot of Gold Team Open shooters have gone down this path already. I'm not sure reaming the chamber would help, as the bullets are hitting the roof of the chamber. It's not really a chamber length problem. I was also wondering if it's a magazine follower issue. The Grams followers don't have sides to speak of and so can tilt upwards under spring pressure. Link to comment Share on other sites More sharing options...
kneelingatlas Posted March 15, 2016 Share Posted March 15, 2016 You misunderstand, I think your feed problem is a cartridge length problem, but to solve it you need a longer chamber. Link to comment Share on other sites More sharing options...

The Grams followers don't have sides to speak of and so can tilt upwards under spring pressure. Your not alone, there are Gold Teams out there that struggle with HP's, and it seems like for no real reason why. Years ago I had some success with Zero because the nose had a little bit more of a point to it, but it still was not 100% reliable. As you mentioned the bullets are hitting the top or roof of the chamber. You can play with the opening of the feed lips on the magazine to try and correct the angle, but you mentioned that all the mags were doing it. This could take some considerable time and patience to fine tune each magazine ( with some occasional trial and error ) to get them all to feed reliably, and you might still get an intermittent feeding issue with the HP's. ( I tried and it was a PITA ) First try the original followers, and see if that adjusts the angle enough and hopefully corrects the problem for you. If it runs your golden. You might give up a round or two but that's better than the alternative. I do not recommend contouring the top of the chamber to help with feeding. This has been done before, but if it's messed up could lead to more problems for you. Better to play with the rounds and magazines first before touching the barrel. Some have no problems with HP. I only shoot RN in all my Tanfoglio's. Best of luck. Link to comment Share on other sites More sharing options...
selecw Posted March 17, 2016 Author Share Posted March 17, 2016 I got hold of some 115gr RN Berrys and Xteme... At 1.165 they seem to feed fine, although I've only tested about 50 so far. I'm also loading up some 1.175s, as they also pass the chamber and case gage tests. I guess the gun just doesn't like HPs. Link to comment Share on other sites More sharing options...
selecw Posted March 19, 2016 Author Share Posted March 19, 2016 1.175 and 1.185 RN both work fine. I'm not going any longer than that. Link to comment Share on other sites More sharing options...
selecw Posted March 22, 2016 Author Share Posted March 22, 2016 Update - with range testing, it turns out that 1.185 is too long for the Gold Team mags. So I am going with 1.175. Link to comment Share on other sites More sharing options...
Garmil Posted March 22, 2016 Share Posted March 22, 2016 If you ever want to go longer 38 super mags work well. Mine will feed 9mm just fine even some 100 grain loaded to 1.105 oal. Link to comment Share on other sites More sharing options...

Interesting. My "big stick" is a converted 38 super mag and needs a shim to stop 9mm bullets nose diving. Do you ever experience that? What OAL can you go up to?

Garmil Posted March 22, 2016 Share Posted March 22, 2016 No feeding issues at all. Can go out to 1.265 or so Link to comment Share on other sites More sharing options...
BeerBaron Posted March 23, 2016 Share Posted March 23, 2016 I can't really help with the problem as I went exclusively to RN profile in my gold team. It's a 38 super though also. Anecdotal evidence suggests jhp are a more accurate design but the rn are just so damn reliable. Link to comment Share on other sites More sharing options...
