S&W 929 Load Data

[deerassassin22]

Whats and alternate for N340?

[mjmagee67]

I am using Bayou Bullets 135gr with 3.9gr of N320 at 1.135 inches AOL for a PF of 129-ish.

My CZ's using the same bullet at 1.120 use 3.7gr N320 for a PF of 127 and 3.8gr gave me a PF of 129.8 at Area 2 last week.

In my S&W M&P 9Pro and Kimber 1911 3.6gr got me a PF of 126-127 and 3.7 got me a PF of 130-132!!!!

Blue Bullets 125g

OAL 1.125

Wst: 4.5

avg:1071

133pf

Mixed 9mm Range Brass

.355 diameter bullet. Accuracy was pretty bad out of the 929 something like 10" group.

Same load out of Open STI was Grouping very well.

I loaded some test bags I had of 142Gr Jacketed .357 at

115PF and

158Gr Jacketed at 110 PF .357 and Groups were down to 2-3 inches

I ordered some .358 Blue bullets to try next. I also am going to sort the Brass and shoot only FC brass

Some of the brass would stick some ejected fine. I cant quite rule it out yet but it doesnt seem to like .355 Diameter

The groups were at 25 Yards

I have been working up loads for my new 929. Here are a couple 8 shot strings I chrono'd recently using 135 gr 9mm Bayou at 1.140 OAL, mixed brass. 85 degrees in the Florida sunshine in December!

3.3 Gr Titegroup avg. 937.1 PF 126.5 and,

3.5 Gr Titegroup avg. 970.7 PF 131.

Will probably settle on 3.6 Gr - better to be safe than have a bad day at the chrono. Shoots nice and soft.

Update 4/10/16: New Armscor brass; 135 gr Bayou; 1.140 OAL; 3.5 gr Titegroup. 131.6 PF. No extraction problems. Sticking with it!

[oteroman]

What diameter are your 135's?

[sargenv]

One more addition.. I was able to drop my powder charge using Black & Blue coated 147 RN's..

My load:

Starline 9mm brass

3.7 gr Alliant Herco

147 BnB RN sized .357 (mine were the red coating)

Federal Standard #100 SPP

I chrono'd 128 at home.. and when I went to Vegas in February for the Bad beat Challenge, I also chrono'd there at 128 PF.

[alfsauve]

Just got my 929 back from the smithy. My standard 9mm load and results from this weekend.

124gr Xtreme plated

CCI primers

4.0 grs of Titegroup

Avg Vel 1023

Avg PF 126

SD 15.42

2 caveats:

Obviously the CCI primers are not ideal and need to be replaced with Federal, but it's what I had loaded.

The 124gr at these velocities had pretty poor accuracy. Using Am Eagle 147gr and 115gr factory it was much better. So I'll be testing some 147gr loads soon.

[firewood]

I've been using a load almost identical to Dpr17 in post #46 & 54. Except I'm using 3.4g Titegroup and coal 1.136 (135g Bayou RN coated), federal brass and primers, Revolver Store moons, the inexpensive spring steel ones. I haven't chronographed this but I know it makes pf. Ejects easy. My only complaint is that it makes the cylinder very hot when you get down to business.

I've been using WST and the cylinder has never been too hot to handle from what I've noticed. My current load is 3.5 with a black bullets international 147g .356 seated at 1.135. Federal brass easy ejection. I've shot this load at psa shootout and walls of steel where you stand and shoot 25 to 30 steel targets no issues handling the cylinder. I don't remember what of it is but its above 125 from what I remember.

[firewood]

Actually, I put my thumb in the window during reloads and it's forcing cone that's really hot. I think I'm going to try fooling around with a different powder, I hadn't considered WST but that's a possibility and maybe HP-38

[VanMan1961]

what crimp die are people using? I was using a Dillon crimp die set for a very firm crimp @ .374", and still getting some bullet creep. After firing off 7 rounds, the projectile of the 8th round has crept out so the COL is now 1.145" instead of the 1.100" I load to.

I'm still using my semi-auto load of 3.5gr N320 @ 1.100 with a CCI #500 primer, and will be developing a load for my 929. Will need to up my powder charge to at least 3.6 and use Federal primers.

I'm thinking of switching to a Lee factory resizing and crimp dies to see if I can get a more secure crimp.

I've heard of using roll crimp dies when reloading 45acp for 625's, but I couldn't find a roll crimp die in 9mm and could not find any 9mm projectiles with a cannelure or crimp groove.

So what are other folks using to get a good crimp when reloading for your 929's?

The crimp doesnt hold the bullet in place. The neck tension from sizing holds the bullet. Switch to a lee sizing die and see if that solves your problem. I had setback problems with a hornady die specifically with Montana gold bullets, switched to a u die and never had that problem again. A regular Lee die should size better though. might not need a u die.

agreed. The day I switched to an EGW U-die was they day every weirdness I had ever seen with loading 9mm brass went away.

Highly recommended. The EGW u-die in particular can be adjusted all the way to the shell plate and it does close to a full length resize which as far as I can tell is as good as you can get without going to a roll-sizer.

[Ty Hamby]

Here is my load I developed early last year. about 8k rounds fired between the two guns.

My 9mm 929 load is

Bullet: BBI 160gn .358

Powder: 2.8gn N310

OAL: 1.20"
Primmer: Federal 100

Brass: Starline Short Colts

Moon Clips: Hearthco .025 EDM cut

Press: Dillon 650xl

Station 1. Lee 9mm (standard)
Station 2. F powder funnel
Station 3. Powder Check
Station 4. Lee 9mm seat die
Station 5 Lee 9mm FCD

Below are 5 shot 25 yard groupings from both mine and my wifes ICORE 929's

[IHAVEGAS]

 

Just got mine back from Ace revolver guru. 

Used loads I had been shooting in my cz at just a smidge over 130 pf. 

1.15 oal, 147 grain .356 sns truncated cone, 3.2 titegrooup, federal primers, range brass but sorted for winchester head stamp.

Chrono was 857,847,854,859,845,862,860 - need 850.34 to make 125 pf. 

Only had 150, but no issues and no sign that the cases were going to want to stick. 

Shot 5 from last clip aimed at center of head at 32 yards with butt of gun resting on a cloth on table. 

I'm not sure where to go at this point, beyond upping the load a smidge to stay safely above 125 pf. . What I already had loaded seems to shoot as accurately as I am capable of and I do not have access to a ransom rest. Am tempted to just switch from sns 147 .356 tc to round nose and call that good, but I hate to run the gun with less accuracy than it is capable of.

I'm new to reloading for revolvers, can you use long OAL for 9mm? like out to 1.20 or so?

Largest OAL  I've been able to get away with in my 929 is 1.7.  I'm using Blue Bullet 147 grains with 3.2 grains of VV N320.

[pskys2]

Ty seems to have done a LOT of work and research, listen to him. 

My 627 with 38 short colts love the 160 RN, and are ok with lighter jacketed but doesn't like lighter lead/plated bullets.  But a 929 might like lighter weights due to twist and bore size.  But save yourself time, listen to TY.

The 929s definitely seem to do better with long bullets.

I just slugged my 929, and with cylinder throats of .357 and barrel of .356, I think these are pretty much the same dimensions as your 627.  I'm looking for 160gr RN, but they are not quite as plentiful up in her Canada.

[VanMan1961]

got a chance to run some test batches through the chrono.  Will do some accuracy testing at the next range trip. 

I tested some benchmark 9mm ammo and the 147gr/3.6gr Titegroup reloads I developed to make minor PF in my 929.  In my Grandpower X-Caliburs, they are significantly faster.

I then tested some loads I developed with some 38/357 bullets that are .357 dia (158gr plated round nose and 148gr plated hollow based wad cutters)

Note: the cells in pink didn't make the min 125 power factor. The wad cutters are just something to play with for accuracy.  I won't be using those in IPSC lol

[VanMan1961]

I got a chance to do some accuracy testing using a fresh (new and untinkered with) 929.  I posted the results in this thread http://forums.brianenos.com/index.php?/topic/239265-slugging-a-929/&page=2

The net was no definitive difference in accuracy between 9mm and 38sp bullets reloaded into 9mm cases.  I did find a load (124gr .355" bullet HP, N320@3.6gr) that gave very tight groups so I'll be following that one up for bullseye and steel shoots

Great stuff.

Finally got a chance to put some serious time in shooting my loads (1.15 oal, 147 grain .356 sns truncated cone, 3.2 titegrooup, federal primers, range brass but sorted for winchester head stamp.Chrono was 857,847,854,859,845,862,860 - need 850.34 to make 125 pf.) yesterday.

Very unscientific but, 300 rounds, 0 issues with brass sticking, hitting the head box alpha at 10 yards freehand is not hard (I was typically 7-8 with the miss very close).

Conclusion - bump charge up a tad to insure 125 pf and switch to round nose for better reloading - then call the load good and work on my shooting and gun handling skills.

Bayou Bullets shot great our of our 627's both have 358 Cyl and 357 barrels, Load 358 bullets and let the barrel size them as they go down it LOL

All groups I've shot have been hand held and will shoot the x on an icore target at 25 yds.

SL 38 short colt brass, Fed spp, 3.0 grs. titegroup, 1.150 oal

Check with Dennis at Bayou and see if he can ship to Canada

Hmmm.

After 400 rounds or so of sns 147's (.356) my accuracy was going off. Put a bore light to it and the barrel is leaded up really heavy all the way to the muzzle. 

I'm new to this gun so may be missing something obvious, perhaps .356 diameter is part of the issue and the bullet is skidding in the grooves or something. 

Thoughts?

Have shot going on 10,000 rounds or so of this load in my cz's with zero leading issues.
