Harleyhater Posted April 29, 2017 Share Posted April 29, 2017 Recently purchased a CK arms 9mm major open gun. Question on how much powder, projectile weight, powder type. What are u all using or had experience with? Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted April 29, 2017 Share Posted April 29, 2017 For a beginner, I strongly suggest WAC or HS6 under 124 gr JHP's ... End up around 7 gr WAC or 8 gr HS6 - have to start a grain lower and work up, slowly, with a chrono. Both are great loads - I have used both for the past ten years Link to comment Share on other sites More sharing options...
Harleyhater Posted April 29, 2017 Author Share Posted April 29, 2017 That sounds good. I have heard great things about hs6 but have never used it myself Link to comment Share on other sites More sharing options...

racer-x Posted April 30, 2017 Share Posted April 30, 2017 Many CK Open 9's come with short throated barrels - mine did. First thing you need to do in working up a load is determine how long you can safely load OAL for YOUR guns barrel using your bullets. Do the 'plunk test'. I shoot Montana Gold 115 & 124 JHP's in my guns. These just barely contact the leade at 1.140 OAL. I'm currently loading at 1.130 OAL to give a little clearance. Longer loads like 1.165 OAL are definitely preferred in 9 major to increase chamber volume & reduce peak chamber pressure. But NOT if they are pressed into the leade. Shooting longer loads like 1.165 OAL in a barrel like mine is asking for trouble including: - increased chamber pressure - possible failure to go completely into battery (this adds risk for case rupture or FTGB) - possible bullet extraction when unloading chamber To be safe, check your barrel first and be sure.

racer-x Posted April 30, 2017 Share Posted April 30, 2017 172PF loads in CK Arms Thunder 9 (PVD barrel) Bullet - 115gr Montana Gold JHP Primer - CCI SPP Powder - 8.6 gr HS-6 -or- 7.4 gr WAC OAL - 1.130 The HS-6 load feels best to me, but both are nice.

Harleyhater Posted April 30, 2017 Author Share Posted April 30, 2017 Can't thank you guys enough. This has been really eye opening to the absolute variance in loads. Very helpfull Link to comment Share on other sites More sharing options...
zzt Posted April 30, 2017 Share Posted April 30, 2017 (edited) H, some barrels are a lot faster or slower than others. Some bullets are faster than others that look to be the same. You just have to work up the load and chrono. What counts is making PF in your gun. Edited April 30, 2017 by zzt Link to comment Share on other sites More sharing options...

Do you crimp that tight to avoid the 115gr bullet pulling out of the case? Do you use a specific 9mm head stamp? Link to comment Share on other sites More sharing options...
Gooldylocks Posted May 3, 2017 Share Posted May 3, 2017 It is a bit more crimp than I normally would do, yes. But back when I was shooting plated I had a couple back out from recoil in the magazine. It has never happened with jacketed, but I tightened up my crimp just to be careful, because that is a very stupid way to zero a stage.

That's really more a function of the sizing die you use, and the brass of course. Has the tighter crimp affected accuracy, at all? Link to comment Share on other sites More sharing options...
Gooldylocks Posted May 3, 2017 Share Posted May 3, 2017 No it hasn't, not with jacketed. They still shoot sub 2" at 25. I use a U die, so it's as tight as it gets. I'm sure it is just the slick nature of plated bullets, and it's probably overkill on my part, but it gives me peace of mind.

zzt Posted May 4, 2017 Share Posted May 4, 2017 I haven't found crimp depth to affect accuracy at all. I set my crimp to avoid bullet set back. I've never had any bullet fall out. For soft Rainier plated bullets, I require less crimp. It still take 6-7 good whacks with a bullet puller to pull the bullet. With Xtreme (harder) plated bullets, that amount of crimp releases the bullet in 1 or 2 whacks, so I crimp deeper. I'm about to load up a bunch of XTP and HAP bullets, plus 3000 155 MG JHPs, so I'll experiment with crimp depth with them. Link to comment Share on other sites More sharing options...
