Wow 10.5gr in a normal 9mm load!!! Thats extreme. I guss any powder works if you only want the bullet to fly at any cost.

It is way to slow for 9mm. Sell it and buy something else.

Maybe i misunderstand. But are we talking about the normal crimping the case after bullet seating? And just do that harder? If that helps it's great. But I don't understand why i should. You are making the bullet i a way smaller which to me would have the opposite effect.

I tried a 147gr bullet from ARES. It's lead bullets whit som plastic coating. I use 3.3gr N320. About 25% tumble.

Been have some issues with some softer bullets tumbling. But never shoot those bullets when the gun was new so I cant tell if it's the barrels fault. When I look inside the barrel I imagine the lands are not as sharp as they used to be. But since I have nothing to compare it to I'm not sure. How much life can you expect from a barrel?

wow 3,7gr thats what I use behind a 135gr bullet to make 130pf. Seems like the CZ barrels are tighter ore something.

True, for most a lighter TRS also makes trigger freeze more common.

Thanks. I actually got hold of some 124gr bullets of the same brand and model. And they shoot good. They are very even and well made. But if someone else have any more experience whith 147gr FP it would be appreciated.

Tried this question in the 9mm forum but no response. So I decided to try here instead. I like the feel of 147gr bullets and been shooting them for a while. The brand I used before I cant get anymore. Thinking about the Plated Frontier 147gr FP. I have to buy at least 10k so I have no possibility of testing them prior to buying. Anyone have experience whit that combo. Use N320. Mostly concerned about accuracy.

I think this thread is missing one very important issue. Tweaking this spring is the easiest way to improve trigger pull. When you do this you weaken the spring by putting abnormal tension on it. I think that's one big reason for i to brake.

For what i can understand it should work. Been interested for the 6.5G a wile. But have no experience. But I think 1-8 and 1-7.5 is preferred whit the heavier bullets. check the compensator/suppressor if there is one so the bullet don't hit anything. If not my first step would be to try a lighter bullet. Or maybe a different powder. But that's more of a long shot. My best guess is that the design of the rifling itself in combination whit twist rate and bullet, and bullet speed is causing it. And there is only two parameters you can change easy. The other two is tuffer

I know two things that was a problem for me. For one, Use .356 diameter bullet if it's the softer copper plated bullet. The .355 is impossiblto get shooting. I Europe the copper plated bullets are very common. I don't know if it's that common in the US. And one other thing that I already new and that's kind of embarrassing. I have been crimping by bullets a bit to hard. I did not realize this because I am not used to the copper plated bullets. The bullets give in very easy. I notised this when I took one bullet out because the primer was inserted up side down. And the bullet was damaged by the crimp. Stupid me

Interestingly, there may be a biological reason for this, too - I have some theories, but nothing I can prove. It's on my list of stuff to write up in a blog post at some point biological!!. English is my second language so maybe I misinterpreted. I hope so anyway.

My Super 1050 seems to work 99,99% now. And the very few problems i now have with primers is more likely related to inferior brass. I use random 9mm bra I pick from the ground. I prep it good, but it will never get 100% whit that type of brass. And it's not much the 1050 can do about that. When I am certain my modifications work 100% I will post it here whit pictures. I have to load som more to be sure.
