[old wanderer]

I have to say reading through all this just tears my heart out. About a year and a half ago I was moving from So Cal to Washington...I could only haul so much in my PU and the moving company did not even want to move ammo or brass..

There in the trash was 7# of 571, 5# of 540, 6# of 231. I only move the large keg of 473AA as I used to shoot it in my 45 acp as well as shotgun....Who would have though all the shelves would be empty????

Man, You should have called, I might have drove over to get it!

For my birthday i took my wife shooting. I made some light weight low recoil rounds to teach her on. g20 with 22# spring
6 grs, 6.5 grs w231 135 nosler jhp started out using the stock spring to make sure it would function. IT functioned perfectly for me my not so for my wife. Also functioned without failure with 22lb spring for myself. I found the 6.5gr loads more accurate for myself.

She started out not hitting the paper @ 20 feet( literally only 7 out of first 40 she fired hit paper), by the time we were done she put them all in 9-8 ring. So I consider it a success.

Great thread, thanks guys. I'm new to reloading, started in April. I haven't loaded for 10mm yet but will starting next week. I have a Mech Tech CCU in 10mm on order. So I'm looking for some good 10mm loads to try in it.

That guess (a rther big one) is a full grain over Hogdon's current max....

[_The_Shadow]

Especially for that fast of POWDER!

[Alycon]

I know your post is kinda old, but I'm desperate. I have a few pounds of Winchester 571 and no load data. Can you help me with some load data?

[MakeMineA10mm]

Hodgdon and Winchester recently admitted that several Hodgdon and Winchester powders are identical powders, packaged and marketed separately. Win 571 is one of those. It is the same as HS-7, a very well thought-of 10mm powder. You can use any data you find for HS-7 for your Win571, and there's a ton of that data over in the Hodgdon powders thread.

Well, I kind of "guestimated" and picked a charge weight.

The components are as follows:

180 Winchester FMJ bullet
Winchester 10mm nickle cases
CCI Standard large pistol primers
6.8 gr W231
Stock G20 except for 22# Wolff recoil spring


The results are as follows in (fps):

1098
1100
1082
1077
1093
1099
1086
1089
1073
1079

Average was 1088 fps
Std Dev 10fps

This is very close to 1100 fps, pretty impressive for a plinking powder. Std Dev is pretty low too. I think the reason why the Std Dev is so low is because W231 "throws" and meters so well.

Primers appeared not to be pushed out or flattened, and case bulge was not extraordinary. I haven't any idea if this is a mid or max charge. It doesn't appear to be a max charge. I feel reasonably comfortable with this load and don't feel compelled to push it farther. W231 burns about as well as any other.

Finally, if the esteemed moderators feel that this thread can be used as a "sticky", then I kindly ask for you guys to consider making it one.


Thanks,


BuffaloBo

I know this thread is old, but do you have any data on loading 9mm. I have a few pounds of this powder left, but lost the data book.

[Alycon]

Thanks for the info. I found the web site, but HS-7 and Winchester 571 data were not included. I'm reloading 9mm FMJ and possibly 45 ACP, but can't find any data for any of these powders. Any help on these calibers is appreciated.

[BuffaloBo]

Wow, it's been a while since I posted here.

Noticed, as perhaps some of you have that Winchester came out with a new offering, namely AutoComp.

Anyone try it yet? Seems like it would be similar to WSF. It supposedly produces more gas for comped guns.

Looked at some load data, and it doesn't appear to be too efficient/economical.

Any thoughts?

Worked out very well, as evidenced by my reporting back with results. Gotta remember that as time goes on, loading data gets wimpier and lawyers more bolder.


I also load 40 S&W. My empirical experience has shown that there is a good relationship between loading 10's and 40's. I had developed a load for 40 using anywhere from 4.6 to 4.8 gr W231. No pressure signs, and it burns clean.

I've done load development for almost ten years and have noticed that there typically is about a 2gr difference between 40's and 10mm. Be advised, it is not a hard and fast rule by any means.

So, when I successfully developed the above mentioned 40 load, it seemed very reasonable for me to make that 2gr upward adjustment.

Very similar comparisons in loading were seen using Blue Dot, Longshot, WSF, and Unique. --- All very close to a 2gr difference.

I know this is old but I thought I'd post my load for you in case you need it

Using 124g FMJ
4.2gr W231
OAL 1.155 (+/-) .005

Shoots in everything from my PF9 to my G19 and even my Kimber 9mm

[WRXcelration]

Glad I found this. I just picked up a 29sf this weekend and was looking for w231 loads. Great info. Thanks guys

[Meathead9]

So there I was, loading 45, minding my own business when it hit me. I had just crimped the 200th round of 45 @ 5.3gr W231. With (10) 180gr JHP's that had been homeless for months, and the uniflow set at 5.3gr, I loaded them up. It ended up being a nice, soft shooting, accurate little bunny fart load. This load also cycled my 24# spring just fine, the brass dropped right at my feet. Normally I'm not a big fan of these kinds of loads, but this one may grow on me...


Sea Level, 65* F
6" LWD Barrel
Wolff 24# Spring
1.26 OAL
Winchester 231
CCI300 Primers
Starline Brass

5.3gr

Anyone have any new updated info on wsf powder?

[gofly]

Tried the WSF. It didn’t get the performance of the others, but it was remarkably consistent, night and day to BD on both.


180 fmj, cci 300, 1.260, full turn Lee fcd. She smiled in a stock 20 at 8.6gn, 1160 fps, 25es, 5 shots, 1 smile. At 8.2gn I got 1110 fps 18es, 5 shots

[Taterhead]

Not a lot of you guys get too excited about exploring the other end of the G20 performance envelope, but I have been recently playing around with soft shooting stuff.

I think I might have found loads that would be great gamer loads for those inclined to shoot 10mm. This is still a ways above minimum PF for IDPA SSP, but much softer shooting than what I normally run. The top load below makes major PF. All of the below rounds cycled my G20 flawlessly and grouped very well @ 15 yard. The first load was a tad more dirty than the others.

Powerbond 180 FP
Winchester Super Field (WSF)
CCI 300
Mixed brass (mostly Starline)
1.25" COL
Temp: 60F

8 shot strings

5.7 grains:
Average velocity: 860
H/L Spread: 72
PF: 155

5.9 grains:
Average velocity: 890
H/L Spread: 52
PF: 160

6.1 grains:
Average velocity: 918
H/L Spread: 64
PF: 165

6.2 grains:
Average velocity: 928
H/L Spread: 51
PF: 167

WSF meters quite well. Thanks to Freakshow10mm for helpful insight about WSF. I'm going to set the Uniflow at 6.1 grains. That seemed to be about the sweet spot.

[nickE10mm]

Thanks for the post, Taterhead...

I've always been interested in great loads for target/plinking/hunting/gaming for the 10mm... And actually, they were out of my normal HP38/W231 last time I went for powder so I got a pound of WSF, too.

I use 6.5gr WSF under a 180gr pill and its quite accurate. Unsure if it or HP38 is more accurate but I very much like both powders.

Hi Nick.

Curious, what are your velocities with 6.5 grains?

I have been curious to see how slow I can get and still cycle the stock G20 with 17 pound spring.

Jack, I've got no idea on the velocity. Haven't had a check to chrony any of my 231/WSF loads yet. I'll post here when I do. I'm guessing velocity at 1000fps+ from my 6" Fusion

[gofastman]

if you want LIGHT loads, try WST under a 200gr bullet
