I just picked up 200 rounds of Sig V-Crown 9mm .355 124gr JHP bullets. The only powder I have is Accurate #5 and Win 231 (HP-38). Does anyone have load data for these powders. I have searched and cannot find anything. The Lee reloading manual I have has:
124 gr Jacketed with Acc #5 with a start of 5.3with a OAL of 1.15
124 gr Copper Plated with Acc #5 with a start of 4.9OAL1.06
The Western guide shows:
125 gr JHP Sierra at a start of 4.6 with an OAL 1.035

Can someone give me what has been working for them with the Accurate #5 or HP-38 / Win 231? Or do I need to pick another powder for these loads........

The deeper seated bullets have less capacity for powder and will spike faster than the lesser seated bullet. You will need to plunk test in your barrel(s) to see what length fits. Round nose, truncated cone, hollow point bullets will vary in lengths, and the ogive (roundness or the radius) of the bullet nose will determine the seating depth.

Here is a link for bullet lengths by manufacturers that I refer to when I can't find exact data for a bullet. Maybe you can find a close bullet size.
http://www.jbmballistics.com/ballistics/lengths/lengths.shtml
 
Both powders are doable. Start with the longest COL and plunk test until you get an OAL that works in all of your 9’s. Measure and document. Choose the powder you want to start with first and use min powder charge and work up to max listed.

There may be a bunch of loads that work for us, but may not be favorable in your pistol(s).
 
Thanks for the feedback and link. I will save that link for future reference. I'm new to reloading but I learned real quick to do the plunk test and have even added another test. I check to see if the rounds will load correctly in my magazine . I reloaded some .380 for my Walther PK-380 and had a couple of rounds that were just a smidge long for the mag. Not noticeable when I did the plunk test, or initially loading the magazines, but I did have a couple of failure to chamber at the range. I checked and found that the tip of the bullet was just touching the edge of the magazine and causing the problem.

One more question on plunk test.......I have a Ruger PCC 9. Do I do a plunk test on the rifle as well?

I really appreciate this site with the wealth of info and guidance.
 
Yup, there's some good folks at THR, and most have really good advice.


The short answer is to load the ammo to meet the headspace requirements of the tightest chamber from which you will shoot the rounds. In that way, the rounds function properly out of all your firearms. The longer answer is just how you will measure the headspace of the rifle. I've never done a plunk test on a rifle. :eek:

I'm like sparyv, never done a plunk test on a rifle barrel either.

One thing you can do. Load dummy round long in OAL. A little longer than what passes the plunk test in you pistol barrels. Say .020" longer. Verify the length. Color the bullet with a dark sharpie marker. Place the dummy round into a magazine. Let the slide slam the round into the chamber. Once you extract the dummy round, check if the OAL shortened any. That should give you an idea of pass or fail. If it moved the bullet, is there any harsh markings on the bullet. If no, then I would I would seat the bullet at least. 020" deeper than the OAL. If it didn't move, then I would go by what your plunk test passed at, -.020".
 
I picked up 100 Sig Sauer V-crown 124gr bullets and loaded them in new nickel starline brass with Cci-500 primers and longshot powder. COAL was set at 1.090 this made for a stout very accurate load.
I dont have a crono yet to measure fps and pf but im planning on getting one very soon.
I will post the results when i test with a cronograph.
Mike.

Simple easy answer is ....

The SIG V-Crown line of bullets are made by Sierra and they have loading data for those listed as "Sierra JHP V" in various grains. (You must have just bought a couple of bags on sale from SIG ... I always grab the 147s when they are on sale.)

Anyways, they are a very solid PD bullet design but you gotta roll'em right and get your velocities right based upon your platform. I'm not sure at what velocities you wanna run yours but I'd run the 124s around 1050 fps soooooooo, with that said, lemme go get that for you straight from my Sierra app.

::::::::: long pause :::::::::

Here you go, this should give you a solid baseline with a lot of options. Good luck.

* Orange indicates low pressure loads.
** Red indicates +P loads.

I just loaded 600 of these with Silouette. The 4.6g suggested load will not even cycle my G26. It takes about 5.5g to do that.
I ended up with 6g of silouette with an OAL of 1.100" and get 1050 FPS out of the stubby G26.
The silhouette data seems to be more on for my purposes.

Get the Sierra app for your Android or Apple smart phone.

As soon as you buy your first Sierra bullet, get their manual.

Figure out which gun is tighter.
I have a Beretta and a sten gun. Obviously the Beretta is way tighter, so I plunk test all ammo in the Italian job.

Oh and 1.09'' sounds short for 124gr v crown, I think mine are closer to 1.125''.

I load my 124gr v crown with a plus pee load of nitro100nf. It makes my 1,000fps silencer load. It even cycles the sten gun.

I can't seem to find the Sierra Apple app....."App Not Available. This app is currently not available in your country or region."

I'm in the US and so are you.....what do you think is happening?

Don’t know. Maybe Tim Cook had it pulled off the store because he doesn’t like guns? The Sierra printed manual is $40 and once you have it, no one can take it away.
 
I plunk tested all of my 9MM’s that would get the 124’s, documented, and went with the longest COL that would plunk in all of them.
 
I don’t see why doing a plunk test on the Ruger PCC is any different than a pistol. Just remove the barrel and drop the dummy in.

It’s actually easier to remove the barrel on the Ruger than a handgun.

That is exactly what I did. Did not have any problems doing a plunk test on the Ruger PCC and the reloads run fine.

Well that's a scenario that truly sucks. I've had the Sierra App on my iPad for several years. I looked now after reading your post and my app had the cloud symbol underneath. I never realized that Apple could deinstall an app that was already downloaded on your device...but now I know otherwise. I get the same message that you received.
I suppose that my Hornady and Vihtavuori apps will be next to go.

Mine hasn't automagically uninstalled... yet. But I also don't run every update that pops up so, who knows?

Bottom line, if you buy or request a paper book, no one can take it away or edit it without your knowledge. Books are good like that. :)

I have the book...sadly. My LGS had a copy of Vth Edition on the powder shelf. Reviewed it before buying 8lbs of Hi Skor 700-X...recipes for all my handgun cartridges. Bought the powder, ordered the new Sierra VI off Amazon...and behold...all 700-X data removed from VIth edition. So, yeah, I have the book. No one can take it away. Had to return to the LGS to grab pics of the Vth ed book while they still had it. Still...the app was really handy for my rifle loads.
At least I recently bought the Android app, and it's still installed.
 
I just checked and the app seems to be working normal on my iphone, For how long I don’t know, as it doesn’t come up on the App Store search.

I just got an original first-edition printing of the Lyman No.39 (1953) in my mailbox yesterday. It has information and illustrations you won't find in any modern loading manual, including discussions of how to determine barrel harmonics, load density, seating depth (vs. cartridge length) and powders we know by other names using their old designations - which can be handy when looking for just the right powder for a purpose-built load. I like old manuals and reading. A lot. I suggest you go ahead and get the Sierra 5th and as many older manuals as you have room for in your reloading bookshelf. And buy a new bookshelf just for reloading manuals. :)
 
Load 4.6gr of #231, seat to 1.125” oal. Proven target/match load. If too long to plunk in your barrel, seat to fit. It’s not that sensitive.

Use 6.0gr of #5. It’s just under top load for non+P. Also, very accurate in my experience. Either will do what you want a 9mm 124gr to do.
