I'm feeling adventurous lately and would like to try something different. What is your favorite 357 magnum loads that offers great accuracy out of your guns?

Will with interest follow this thread. Will however not be describing my once upon a time favorite .357 Magnum load. That was whomped up in my younger more innocent (read that ignorant) years. Messed up a nice revolver. Now like Poe's raven, I say, "Never more!" Sincerely. bruce.
 
For me in my K frames it's 13.5 gr. of A 2400 with a Speer 158 gr. LSWC Hpt or cast 158 gr. LSWC. Or in some cases a Hornady 158 gr. Hpt XTP. Just don't need full power loads in my 357's and these are very pleasant to shoot and accurate in my guns.

When I want a real magnum load I load 15.5 grs of H110 / W296 using Accurate molds version of the Lyman 358156 cast bullet . I crimp in the upper crimp groove . It's sits a bit deeper than std 158 gr cast bullets . It sits on top of the powder charge , maybe slightly compressed . I use a SP Magnum primer . It is very very accurate and plenty of power . My everyday " field " load is 7.5 grs of WSF (duplicates using 7.0 grs of Unique ) , same bullet std primer . My K-frame 357's still just as tight as the day I bought them . Regards Paul
 
We were talking about this the other day in "jimmyJ's" thread. Mine was is a 180 grain Hornady JHP over H or IMR 4227, I just could not remember how much! But the thread jogged my memory, 14.5 grains (14.7 is Hornady's current max for similar bullets) The JHP's were discontinued when the XTP's came out but for some reason I seem to have a good supply!

I developed the load for a Marlin 1894 C 18" carbine, but they soon became my favorite in my 28-2 4". They are super accurate in both guns and in my 28, which is mag-na-ported, the recoil feels like 146 gr Wadcutters in a model 10! this is a 1982 load, and back then I could routinely hit 4" clay pidgins at 100 yards (On a berm, not flying!) with much younger eyes!

12.2gr AA#9 with a 158JHP, just over 200PF at ~70F.
Accurate - snappy, but not harsh.
 
Many good loads . First lets figure out just what you want ie hunting , casual plinking , self defense etc . Once thats done pick a bullet thats suitable for your intended purpose . Same with powders again depends on what you want to do . Tell us all that & we can help better . I'll tell you a little what I do with 357 .
I cast & shoot a good bit of my own . I mainly save jacketed for my CF rifles . For casual plinking a med fast like W231 , Unique / Herco , True Blue , Acc #5 , N340 will work & be more cost effective for lower power loads . For general field use / pests a med burner like Blue Dot , Silhouette / WSF , Acc #7 , N350 . For top velocity hunting H110 / W296 , MP 300 , 2400 , Enforcer / 4100 , Acc #9 .
Bullets in revolvers for pests I use LY 358439 when pushed hard is explosive varmit load . More penetration either the Keith 358429 , 358156 , hunting the LBT 160 WFNGC .
In a rifle / carbine the extra speed makes most 158 JHP's too explosive . I like the 180's either a good JHP or a WFNGC as they kill better @ 1700fps than 1100 from a revolver . Personally I limit my shots to 50yds pistol , 75yds with a long gun .
 
The 357 long case can be very accurate with the right bullet and powder load.

Two lead target loads that I like are with the 158 gr Lswc design with;
Trail Boss at ........ 788fps and HS6 for longer targets set at 1108 fps.

I have one 125 gr JHP load with w231 or CFEp at around 1221fps for small targets.

With the 158 XTP I load a practice and hunting load.......
SR4756 at 1235 fps for practice and the real deal with 2400 at 1340 fps.

Lots of other loads that we enjoy shooting, just depends on the distance, targets and amount of noise that your gun puts out.

I second the 15.5 296 and 358156; this load will shoot one hole groups threw my 6" GP100. 16.5 296 and 158gr JHP MAX Load also shoots real good, no pressure signs in my gun. I only shoot 158gr and heavier threw my .357's found them to generally shoot better than light bullets.

Sorry. All My magnums except the 22 Jet start with a 4. I really like 28 gr H110 and a 385 gr WFN by LBT in My .475 Linebaugh. Gets Your attention. First time at the new range uo here a couple of guys came over and asked " what the hXXX are You shooting?"So I showed them and then asked if They wanted to try it. No thanks.
 
For mid range loads I use 13gr of N110 and 158 gr jsp/jhp. For plinking and ringing steel, I use either Trail Boss or Tin Star with a 158 gr plated bullet. Both loads are easy on my revolvers and my wrists.
 
Lately I have been making a lot of one particular load that my Coonan loves and makes fantastic fireballs with. It's a 158gr Zero JSP or a 158gr Montana Gold JHP over 18.0 grains of Alliant Power Pro 300-MP. I also run this in my 28-2.

I ran this load a bit over 18.0 grains on two different occasions and never got any excessive pressure signs except that the velocity topped off at 18.0 and did not increase, which is a fantastic bit of evidence that 18.0 was the sweet spot.

Small rifle primers and a firm roll crimp. These average 1,310fps from my 6-inch 1973-made S&W Model 28-2. The Montana Gold slugs run just ever so slightly faster, maybe 10fps.
 
With a 158gr JHP bullet I charge 16.4gr W296.
With a 158gr LSWC bullet I charge 9.2gr HS-6.

I use a CCI-550 Magnum SPP is used in both.

Always check data you find on the Internet for yourself. Mistakes can and will happen when writing numbers.
 
I 2nd the HS6 load . I drop 9.3 grs using a 158 gr cast bullet . I don't have a chrono but it's pushing that 158 gr bullet plenty fast . I ALWAYS use a SP Magnum primer with HS6 . I like that load so much that I have used the better part of 4# of HS6 powder in that load . Regards Paul
 
10.6gr A5.
!200fps laser accuracy.
Jim
125gr XTP or Berrys` 125gr plated. they hold up beautifully.

11gr AA #7.
Hornady 158g XTP 1280fps.
Bayou 158gn SWC 1375fps.
Both from a Ruger GP100 6".
Slightly better than laser accuracy.
