Most accurate .357 load

Whats your most accurate .357 load, any powder any bullet any weight.
Im sure this has been disscused befor but someone might of had a break through since then.
When I started reloading I was getting good accuracy now it seems the more things I try the further I get from that good accuracy.

Lately I've really liked my RCBS 38-150-SWC over 8 grains of Alliant Power Pistol in my S&W model 28. You could probably use any 150 - 158 grain SWC over that charge.

I've had pretty good luck with 17 grains of 296 under the same bullet, but it's a bit more recoil.

I have heard alot of people talk about power pistol, im gunna have to try it.
Also after I finish this box Im never buying Berry's plated bullets again.
I measured a few of em and they were undersized then I found a few 125 grain bullets mixed in with my 158 grain bullets, thats not cool.
so far my most accurate load has been 180 grain Nosler silhoutte over 13.1 grains of W-296 for some reason it just groups real good.

My most accurate load is as follows:
WW Super-X .357 nickel brass
CCI 500
Speer 140 gr. JHP original bullet, not Gold Dot
9.0 IMR SR 4756
Firm but not heavy crimp
My older M19 would shoot these into one ragged hole over sandbags at 25 yards.
If you want your children to follow in your footsteps, be careful where you walk.
Beware the man that only owns one gun; he probably knows how to use it.
I just hope my ship comes in before my dock rots.

Win brass
Hornady 140 gr. XTP
14.4 gr. VV N-110
CCI 500 primer.

This is a close to max load that shoots superb groups in my handgun. A definite favorite. The only downside is that N-110 does not meter all that accurately in my measure.

My guns never seen a 140gr bullet, I skipped right by them for some reason.
I was given a can of SR 4756 I put it in a box and never tried it cuz I never found .357 loads for it.
Mine actually says Dupont not IMR but it looks real old.
Ill give it a try with the xtp's and non gold dot speer HP's in 140gr if I can findem.
I was thinking about trying some hard cast swc or even dewc if i can find smaller amounts (less than 500) to play with.
Maybe Ill call Mike and see what he's got.

.357 loads


E-mail me at will send you photos of a .357 diameter 148 grain DEWC, double lube groove, that has been made into a "quite nasty" hollow point bullet with a swaging machine. I have been shooting it at full velocity in a Smith and Wesson .357 Magnum snub with excellent accuracy and no noticeable leading. I have yet to shoot that load in a 6" .357 may lead some with the increase in velocity. The only "varmint" that I have shot with that load, hit the ground dead at the shot, and the exit wound was about the size of a half dollar coin.

If those bullets interest you, I will send you a sample to play with. I can't make enough of them, fast enough, to offer them for sale....the swaging process to hollow point the cast DEWC is really sloooooow!

If there is something else you would like to try, we will make that happen at the same time.

Safety Alert

There is a posted load that uses a 180g jacketed bullet over 15,4g W296.

This load exceeds any found in my manuals.
By a lot.

(Which is not to say I consider unsafe in the poster's gun, but I do...)

Yeah most of my books stop arpound 13.5 grains of W296 behind a 180 grain bullet.
15.4 is real close to what I put behind a 158 grain bullet

Once again I am amazed at how far out of his way Mike at will go to make customers happy.
If you shoot cast bullets you have to try this guy, I can not reccomend him enough!!

I'm partial to 5.4 gr. of Titegroup under a 158gr. SWC. In my GP100 this round is consistently accurate, if I help.
Blessed is the man who has nothing to say, and cannot be compelled to say it.

I came up with a load similar to the one that mag41vance had.
It was 15.1gr of ww 296 with a Hornady 180 xtp and Remington
cases with cci 550 mag. primer but I stopped there with slight
pressure signs. It was very accurate but I Wouldn't advise using
it without working up. Once I work up a powerful load I usually never
use it again unless for special hunting uses.
