    Any one have a good load for a Cz 75 with VV Powders...

    N320, 330, 350?

    124 grain FMJ and LRN.
    CCI Small Pistol Primers.

    Thank you.

    N320, N330, and N340 will all work great in 9MM. N320 for lighter loads, N330 for all around good performance, N340 to get a bit more, and then 3n37 to make it really go. If I remember from your posts, Vihtavuori is one of the few powders you can get there. Good stuff though. pricier here than other powders, but not bad if you buy in bulk. I like it in a couple of loads were I have not found a cheaper powder that works as well. It meters very well, doesn't stick in measures, is accurate, super clean, and just hard to beat in some applications.

    I just started playing more with 124 gr bullets in 9MM, so I don't have any specific loads to share.

    I've read that CZs have shorter throats, and don't accept rounds measuring the maximum SAAMI COL of 1.169". If that's the case with yours, we'd need the actual max COL you can load in your CZs. Giving you a powder amount for a round shorter than what I load could be a recipe for disaster, especially in the 9mm Luger.

    The good news is that I believe you have access to the best powders available for the 9mm, Vihtavuori.

    All those are great for 9MM. My "pick of the litter" would be +/- 4.8 grains of N-330 under jacketed.

    Hey AFY,

    N320 has been my go to for 9mm for quite some time. I have also used 3N37 for my hot stuff. I just recently started using N330 and found it remarkable as well. I think you should buy a can of each and try developing your own custom rounds. I only know what works in my Berretta's.

    Good Luck with it, Mate.

    Bonn Journe, au revoir.

    Afy -
    Angus Hobdel swears by 4.0gr of VV N320 under a 124gr 9mm bullet. I find that the N330 and N340 do better for 147gr bullets.

    Ridgeway is correct. CZs have short throats, so the load of powder will depend upon what bullet nose you are loading with. If it's RN then you [usually] have the option of an OAL all the way out to 1.169", which might take slightly more powder. If you are using FP or HP bullets, then the OAL will be considerably shorter (owing to the CZ's short freebore) and the powder will need to be tailored down accordingly.

    When you talk about reloading for CZ you MUST take the bullet's nose shape into consideration, becasue it directly effects the max OAL possible, and therefore the powder load.

    Hope this helps!

    FWIW, I snagged the below from an article a long time ago and saved it. It was reported to have been developed by David Sams for testing his builds:

    Hornady XTP 115 grain JHP
    4.8 grains of VihtaVuori N330
    New Brass
    WSP primer
    OAL: 1.08 / Crimp: .377

    A Sierra 115 FMJ RN or Winchester 115 FMJ HB bullet can be substituted for for a ball load using the same formula as above, except the OAL is 1.130-1.140" (depending on your barrel throat and reamer). This load will hold under 1" at 50 yards in a good gun.

    I have to say, I don't own a gun with that kind of accuracy potential but nonetheless, that load is equaled (in mine) by very few other combinations and bettered by none. Bad thing is, VV is expensive and hard enough to find and N-330 is hardest of all.

    I just shot some Master Match 125 Gr JSP's the other day ($29 per K many years ago on sale) under 5.1 Grs of N330. I got an Avg of 1176 from a 5" 1911 with soft recoil and super clean. It shot really well from my AR, but I did not chrono it.

    Good stuff. I run 4.8 under most jacketed 115's but on the Montana Gold JHP's, I bump it to 5.0...maybe, the different jacket material makes a difference, who knows? I just recently tried N-330 & N-340 under some 147 Remington FMC Match bullets at 3.8/3.9 grains respectively and both grouped really well. I keep coming back to Solo-1000 on the heavier bullets though...very accurate and so soft its almost like cheating.

    Before I switched to Titegroup, I used almost exactly the load in post #7.

    I've been experimenting with 4.0 grs Vit 320 and Precision Delta 124 fmj; I'm using Fed 100s, and Win range brass ***************************************************
    I'll be checking 1.135, 1.142, and 1.147 tomorrow- I expect 1050fps +/-

    I'll let you know if your interested in 320

    P.S. The PD FMJs are shorter & blunter than Win FMJs and the ogive is different. A test showed my CZ allows 1.2+ max COL

    I always use AA#7, but next time I am at Angus's shop I might but some VV just to see - they carry it there.

    Thankfully finding VV in France is easy. I will check what the OAL is, and post back in a couple of weeks, when everything does get to me, and I actually have loaded a few rounds.
    I will be loading RNL and RN FMJ for the time being, since I have just put in an order for a 1000 of each.
    So lets see how things go. :)

    I would love for VV Powders to be there when I want to buy them at my regular shop. I think you will be pleased AFY.

    Hope all is well in France for you, Mate. By the way... how did the can of H4350 work out for you? You were able to salvage some of the spill, I hope.

    LGB... nope couldnt salvage it. Since I was worried about contamination. However I did put it on the grapes... hopefullly will be a good year.
    But 41gr of H4350 under a 139 Scenar is consistently putting me under .5 MoA. :)

    And I thought 4.5 Grs of N320 and 115 Gr plated or jacketed bullets were light. Those must be just a little poof. :D

    Can you not get any of the Vectan powders? They have some that are good for 9mm.

    CZ75 Throats

    I had to have both of my 75's throated to be able to use Remington 124 JHP's. They simply would not go in far enough to fully chamber. That said, I love the CZ 75, it is one fine pistol.

    In my CZ75 Shadow and my Springer 1911 I use VVN320, 4.1, 124g at 1.14. It gives my 1050. Very accurate, clean and feeds excellent. I have used the above with 115g but it feels way better with 124g.
