Bullets Posted June 16, 2016 Share Posted June 16, 2016 Wondering if the heavy plated concave base bullets are ok for major. I have seen lots of people have issues with the standard xtreme rn tumbling and keyholing. Wondering if the hpcb bullets stop the tumbling issue.

Maximis228 Posted June 16, 2016 Share Posted June 16, 2016 I have used 75K 124 HP, non heavy base, without issue in 9 Major. Getting 1.5 inch groups at 25 yards. Link to comment Share on other sites More sharing options...
peterthefish Posted June 16, 2016 Share Posted June 16, 2016 All the Xtreme HPs are heavy plate, not sure what heavy base is..? Link to comment Share on other sites More sharing options...

Targetpractice Posted June 16, 2016 Share Posted June 16, 2016 Would like to know the answer to this as well. I had 124gr rn xtreme tumbling with hs6. Link to comment Share on other sites More sharing options...
fmj3 Posted June 16, 2016 Share Posted June 16, 2016 Why plated when you can get jacketed for less? Well if you buy at least 2k from PD they'd be cheaper. Link to comment Share on other sites More sharing options...
Sarge Posted June 17, 2016 Share Posted June 17, 2016 If you dig around on the xtreme website you will read they don't recommend standard xtremes at open velocities. Only the heavy plate and hollow points are rated for high velocity open loads Link to comment Share on other sites More sharing options...

Only the heavy plate and hollow points are rated for high velocity open loadsyes i have seen that but is that refering to the velocity or because they tumble?

Only the heavy plate and hollow points are rated for high velocity open loadsyes i have seen that but is that refering to the velocity or because they tumble?Probably both? The thin plating will shear away at near 1500fps probably. Once the plating is compromised there is no limit to what the bullet might do. I would assume tumbling could be expected. In an open gun it wouldn't take much plating in a comp to produce radical bullet flight. FWIW I have shot A FEW 124 HP and HPCB OVER1400 and they were nice clean holes Link to comment Share on other sites More sharing options...

FWIW I have shot A FEW 124 HP and HPCB OVER1400 and they were nice clean holes i stick to 124s since i shoot a shorty. I try to stay around 1375fps which is well under what they rate them at. Think they would still be getting damaged at that velocity? Link to comment Share on other sites More sharing options...

Think they would still be getting damaged at that velocity? Personally I wouldn't think so. If you can see NO evidence of them hitting the comp, You might start pulling a few and check the crimp. If there is anything other than a very slight indentation in the plating back the crimp off and test again. Link to comment Share on other sites More sharing options...
accu9 Posted June 17, 2016 Share Posted June 17, 2016 HPCB bullets work great in 9 major. Just remember, even the HPCB are sensitive to both under and over crimping. These are not jacketed bullets and they cannot be treated as such. Link to comment Share on other sites More sharing options...
Slostang Posted June 17, 2016 Share Posted June 17, 2016 I've shot about 5k of them at 1400fps without issues. Link to comment Share on other sites More sharing options...
acoop101 Posted July 3, 2016 Share Posted July 3, 2016 If you look on xtreme website they have jacketed 9mm 124 grain for sale. Sent from my XT1565 using Tapatalk Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted July 8, 2016 Share Posted July 8, 2016 Pat, I saw your comment that the Xtreme 124's "held up well at Major velocity", but were they as accurate as MG or Zero? Link to comment Share on other sites More sharing options...
P.E. Kelley Posted July 9, 2016 Share Posted July 9, 2016 Pat, I saw your comment that the Xtreme 124's "held up well at Major velocity", but were they as accurate as MG or Zero? The answer to accuracy was in the article...that is why I write them...for my colleagues to read. Did I compare them to other bullets? No, I did not. But sub 1" groups at 28 yards might be considered...ok? Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted July 9, 2016 Share Posted July 9, 2016 Sorry, I guess I missed the accuracy assessment. YES, sub-1" at 28 yards is beyond my capability. Thanks Link to comment Share on other sites More sharing options...

You got the inference! Thanks! Oh and 28 yards (normally 25 but I got lazy) Link to comment Share on other sites More sharing options...
