[Resizing loaded 9mm]

I had this same question as the OP  earlier today but with .357 mag.

I bought a set of used RCBS dies and I found out there was a nick in the threads on the outside of the sizing die body, so the die wouldn't thread down far enough. 6 out of 50 wouldn't chamber.

So, good question.

If you're loading for suppressor use, you're probably interested in finding a quiet load, which is another variable on top of the usual stuff about accuracy and soft recoil. Also, the "soft recoil" bit pretty much goes out the window when we're using a suppressor with a booster on it; the small differences in recoil between one powder and another are mostly overpowered by the booster.

 

With that in mind, I don't like any of the above mentioned powders for suppressor use; they all produce a sharper sound. The quietest suppressor powders I've found are not the usual suspects for competition shooting. My personal favorite is Green Dot, closely followed by American Select and Universal. Any of those three will do what you need for a 124gr suppressed load, and will be quieter than something like Titegroup. 

 

Keep in mind too that your pistol and suppressor may or may not cycle with a subsonic 124gr load. A tighter barrel lockup has more trouble cycling. I've got one G19 barrel that will cycle 125gr coated subsonics, but another barrel in the same gun that is more accurate but will not cycle them, it needs at least a 135gr bullet to cycle and stay subsonic. 

I didn't even think about the  cycling issue. I'll just get somebody to supersize the barrel so it'll take the biggies. Seriously what's the right way to say it?

You've gotten my attention with better sounding powders, Bi mart has Green Dot, would it be a good choice for 147gr also. Are you talking about a lower tone?

Consider getting the barrel cut to let you load longer, too. I did all of my Walthers and can feed them even the grumpiest 147 out to 1.145” now.

 

I will definitely get the barrel/throat/leade cut to allow it to chamber longer bullets. What's the right way to say what your proposing? "Reaming the throat"?

And who is doing that work that you folks would recommend?

There is a new profile in 115, 125, and 147  just out from Precision Bullets.  I have some 125s and 147s on the way to try.   The claim is much easier loading  longer for guns like CZs.   I have loaded a lot of RMR Match Winners and yes they need to be short.  The RNs are more forgiving.

I'll have look at those.

Without a chrono you are pretty much SOL,  BE 86 is kinda slow, I dont imagine it would do that well reduced that much. TG is more tolerant to low volume ,  As a fairly fast but bulkier powder I suspect 231 would hold accuracy best at lower velocity. But really without a chrono you are just guessing. 

A chronograph is definitely on the short list of items to get.

And BE-86 is out as a candidate for 124gr. subs.

I have used BE86 for some accurate but faster target loads in my P09 with RMR 115 and 124g bullets, but its not the powder for lower power stuff.  W231 is much more in line with that, although I use Sport Pistol which is roughly between W231 and Titegroup.   You would probably be better off working with 147g bullets and light charges of Titegroup for starters. 

I've got a few subsonic loads with Titegroup and 147gr bullets from 3.1gr to 3.4gr. they work great in my Glocks. I'll have to find a 147gr with an Ogive that my CZ like, or that can be loaded short.

I used W231 with the RMR until I switched to sport pistol at the beginning of this year. 

 

Heres the chrono on my load of 4.1 W231, RMR 124 FMJ RN @ 1.125-1.128” OAL, WSPP

I'll play with your w231 load above. I gotta get some sport pistol, but can't find it locally

Thanks for the responses folks, I've got what I feel is a good soft shooting suppressor load for RMR 147 grain match winners with titegroup. unfortunately I'd have to load those bullets at 1.09" OAL in my CZpo9. The bullet manufacturer recommends 1.13" OAL and I'm new enough at this to not go against manuf. recommendations. Gotta take the kids to school.

Hey folks, I'm looking for a recommendation of a starting load, for suppressor use (Obsidian 45) with a CZ P09 that has a short throat.

124gr RMR round nose

BE 86 or W231 powder, (I also have Titegroup)

1.125" OAL

CCI #500 SPP

Brass can be anything, I have at least some of most brands.

 

I've got recommendations on good mid range to near max loads with BE 86, I'm just not sure where to start on the lower end. I don't have a chronograph.

Thanks in advance,

Nate

I'm busy tonight but I'll try and get some pics and part#s of what I'm using.  basically you need to expand for the depth your seating so you have to calc that from your OAL and bullet length.  The rifle length NOE inserts can be modified on a good bench grinder with a little skill in a few minutes and then the radius polished.  With 135s you will most certainly need to do this unless your gun plunks long.  In this case, or with shorter 115g and some 124s,  a pistol length insert will be fine as is.

Love to see some images of what you have going on, part #'s too. When time permits.

That makes sense, I'll load up some dummies and then pull them to check. I just ordered up 3 sampler's.

People have different interpretations of "need" I guess, but I hate to see a new reloader be misled. Your RCBS die set expands and flares the case neck just fine, you don't need any other die. Some people prefer to use something else, but that's preference, not need. 

You do need to flare the case mouth, and lead bullets (cast/coated, lubed, swaged, whatever) need a bit more flare than jacketed bullets. You'll do this with the second die in your RCBS set, and applying more flare is done by screwing in the stem of the die a little farther. 

 

If you prefer to use something like the NOE expander, Lyman M die, etc, you can certainly do that and might or might not find some advantages with those. However, you can load excellent quality accurate cast bullet ammo with the dies you already have. 

Is there any way to explain how much more to flare versus FMJ? or is it trial and error?

With FMJ I flare just enough so the bullet will sit on top and not fall off, I have done about 100 rnds of cast and I used the same method, didn't get any lead shaving off from the case but these were .355's.

I appreciate the responses folks.

I've just read this 11 page thread over two nights and am just about to make a Brazo's purchase of a couple sample packs in a couple different sizes 135 gr .357 an 135 gr .358 diameter's. My shopping cart is loaded but before I do it, I wanted to get more information on the case mouth expansion prior to seating a .358 bullet.

So. I'm working with an RCBS Rockchucker with RCBS carbide dies and have loaded approx. 500 to 600 rounds, all FMJ or cast .355 conical nose (Georgia Arms).

So I'm new.

I read somewhere about an expanding die to expand the neck from "NOE", but I also read that, that tool has to be modified to work correctly. Is that what all you folks are doing to seat these larger diam. bullets?

I haven't slugged any of my bore's and don't have a micrometer yet. I just thought I'd pick up a few different sizes and see what shoots best.
