All is good in the universe again. Did some load dev with Vectan and with a comfortable margin over factor there wasn't a hint of tumbling. Shout out 60 Vectan charged rounds in total to be sure and they ran true. Put a mag full of the 121 charged ones through at the end and 5 of the 18 key holed at 10m.

Thanks a bunch for the powder to try NoStepOnSnek88. I'll lay in a few bottles.


Glad you found a replacement powder if Somchem isn't available.
Maybe I'll purchase your S121 from you after I've done some testing with the bottle I bought, but that might be awhile.

It's not a one barrel issue. The tumbling occurs in my three 9mmP pistols and in two belonging to friends. Exactly the same bullets work perfectly in 38 fired from my 357 revolver and a 158gr bullet of the same alloy works fine at 1350fps in the 357.


Linotype will tell you for sure if your assumption is correct.

There is no universal lead hardness that works in everything, lead bullets are tailored to the barrel they are shot in, which is why there are so many alloys / lubes / coatings / sizes per caliber. Otherwise there would just be one.

I still say all 5 of those 9mm pistols will have the same depth in the lands, which doesn't work with softer lead above a certain pressure.



Using a more expensive alloy for one calibre is not a viable or convenient option for me. Changing to a slower powder is an almost no cost fix and takes me back to a configuration I know works perfectly with none of the ballache]]> Reloading Methodology oafpatroll https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6519 Re: MS / MP200 equivalents https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6518 Sat, 22 Feb 2025 04:19:49 +0000 Reloading Methodology Tripodmvr https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6518 Re: MS / MP200 equivalents https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6517 Sat, 22 Feb 2025 00:38:16 +0000

Thanks for the suggestions. I have also been referred to Vectan Ba9 1/2 so will give that a whirl too if it's available.


I've used Vectan since 2019 with the Silver Rapids 147gr, 3.3gr powder for an average FPS between 850 to 860 through the Glock 19X and CZ SP-01 SHADOW.

I'm happy to donate you some powder if you want to run some tests and see if it can work for you :)



Thanks for the offer snek. Is it the 9.5? If so I would like to buy enough off you to load 50 rounds or so at starting charge.


That's the one, I haven't personally seen any other Vectan variants on sale in South Africa, no need to buy it, I'm happy to donate enough powder for 100 rounds or so to you.  :)



Thanks, much appreciated. Will ping you to arrange. The stuff seems to be fairly freely available and isn't fiendishly expensive so if it works I'll be chuffed as hell.


Back in 2019 it was going for around R750-00 for the 500G "tin", not so much anymore  :'(  :'(  :'( 


I might be wrong, but as far as I know Hodgdon CFE Pistol is about the same price as the Vectan now, and yes it's only 454 grams instead of 500 grams as the Vectan, and I believe, Hodgdon CFE Pistol is also very close to Somchem MP200.]]> Reloading Methodology NoStepOnSnek88 https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6516 Re: MS / MP200 equivalents https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6515 Sat, 22 Feb 2025 00:17:24 +0000
That will tell you for sure if that barrel needs harder lead to shoot properly.

I can give you a small block of linotype, it'll make a handful of bullets for you to test.

That will tell you for sure if that barrel needs harder lead to shoot properly.


Thanks for the offer but I'm not keen on trying to address the issue with a different alloy for 9mmP only. Nearly 100% of my lead is recovered range scrap and I use it for everything from birdshot to rifle bullets. Will be much less PT and probably cheaper in the long run to find a propellant that works for that application. If Somchem ever starts making ms and mp again and it's cheaper than whatever I land on I'll probably lay in a rest of lifetime stock and be done with it.]]> Reloading Methodology oafpatroll https://systemz.online/reloading-methodology/ms-mp200-equivalents/paged/2/#post-6512
