Flattest shooting 357 load recipe?


March 18, 2008, 07:48 PM
For a 6" 686-3. I'll probably use a 110 jacketed or HP, and crank up the velocity. Do you have a recipe you'd like to share? If so, what can you tell me about it?

I have been thinking of loading up some 110's in front of some 2400 for varmint loads in my lever action. I havent worked up a load yet.

In the .357 Magnum, I like the 110 grain Hornady XTP with Blue Dot (consult loading manuals for charge weights, and follow safe loading practices). Out of an 8 3/8 inch S&W 586, the velocity averaged 1790 fps. I shot an armadillo rooting up my Dad's yard at about 20 paces, and the 110 grain XTP split it in half. Literally. Two pieces.

Just my .02,

Keep me posted Seafarer.

That's about what I was thinking, Leon. Were you using a max load?

a fair dose of titegroup otta get that 110er jumpin purty good!!
nope !! h110 does it again accordin to there site !!
talkin about blast!!!!!!!

Wow GP100man, that's the powder. Off of Hodgdon's site, they list a 110g XTP making 2078fps! That's gonna be a fireball!

Just because you CAN load 'em to over 2k fps,doesn't mean ya SHOULD.

Floppy D,

If memory serves me right, it was a grain UNDER max. It was really accurate, right around an inch at 25 yards from that long barreled 586. I tried working the load up closer to max, but accuracy fell off.

The armadillo never knew the difference :).

Just my .02,

As I recall, there has been discussion regarding top strap flame cutting with S&W 686 handguns using 110 grain bullets at the high end. You might want to check over a smith-wessonforum.com.

About 11 grains of HS-6 or Power Pistol (max loads for a 110, so be careful and start lower.)

I don't shoot light bullets in .357 Mag. I like 158's.

my nuclear option for my 686 runs 158 hard cast over 2400.

it was this handload that brought on a whole new level of respect from me for the 357. i can hold tight enough groups out to 65 yards that, if it were legal here (its not), i'd use it for deer.

I don't think any powder will give you higher velocities than H110/W296 with a 110gr XTP bullet. Be careful not to push that 110gr Hornady XTP bullet too fast because it will probably fail. I checked the Hornady data and they recommend their 110gr XTP bullet for between 900-1400 fps. I would guess any powder suitable for Magnum use will be able to push a 110gr bullet up to 1400 fps. I wouldn't recommend you exceed Hornady's recommendation.

I'm not attempting to destroy my revolver, that's why I'm dipping into the pool of knowledge here before moving on.

Thanks for the warnings and the recipes, I'll do some more research before I start filling them up.

Give H110 a try, you will be happy you did. Also H110 requires a magnum primer when using it. Good luck.

Any idea what kind of speed your getting out of that one.

The bullet hits the target before I squeeze the trigger!:D:D I canít find the book I took it out of it is still boxed up somewhere and I canít hobble around to where they are, sorry.:(

I bet its fast. Alliant doesn't even list 2400 for the 110 grain bullet. With blue dot they have 2000 fps listed. 19 grains of 2400 shooting a 110 out of a 20 inch barrel would be smoking.

Why "flat shooting?" In general, the .357 Magnum shoots flat out to any range the average handgunner can hit.

At the same time, a 110 grain bullet militates against a flat trajectory over longer ranges -- because of the low ballistic coefficient.

I have several bags of 110g JHPs that are marked 125g. I weighed them, so that's how I know - good policy.

I did some research and found that 8 ~ 8.5g of W231 made for a magnum load and while I don't like fast powders for magnums, with such a light bullet, I made an exception.

They were impressive, but an experiment only. They shot well, hit hard and grouped nicely, but for me, it's all about heavy bullets and H110/W296.

Just for fun. I just want to see how far my revolver shoots point of aim, or very close to point of aim. Eventually it may be for hunting, and if so, I'd like to know it's limitations as well as mine. Since I know neither right now, I'm experimenting with a handful of loads. I found lots of data for light loads, and for heavy bullet loads, just no data for fast loads. I'm sticking within published limits, I just wanted to hear some input from folks who may have tried.

Thanks for your input everyone!

i usually run it around 15grs. h110 under a selfcast 158grainer that fits tite & lubed good!!

I wish the Hornady FTX bullets were available as components. Would love to see what my .357 could do with those.

March 25, 2008, 12:00 AM
I have always wanted to try and pull some Glaser Safety Slug bullets (85g IIRC) and see how fast I can get them to go.

Now that is how you would make a varmint gun out of a .357mag rifle.

I took a handful of Golden Saber's to the range (125g GS loaded over Bluedot, about 10% less than max load, CCI small pistol mag primer) as well as an assortment of 38 and 38+p loads, some factory 357, and a few 200g Castcore's just for variety's sake.

The GS's were fiery, to say the least. In an indoor range, I could literally feel the heat on my face. Accurate as hell, but I wouldn't shoot those for fun. Next up were some powderpuff 38 loads (cast 125g, over some unique). Recoil was just over 22lr levels, and my 686 felt like a laser. I managed a few 12-shot baseball-sized groups at 20yds, which is really good for me. Last, I tried the 200g Castcores, which were firm, but not sharp like the Golden Sabers.

25 yards is not going to tell me anything, I really need to try these at 100yds off of a rest. For indoor ranges and general plinking, I'm sticking to the cast 38spl loads, for both economy and ease of use.

What I DID learn, overall, is that the pace and simplicity of a revolver are the zen of shooting. :)

I used to load 17.6 gr of 2400 and a 125rg JHP (Hornady). My 686 6"bbl (no dashes) was able to produce cloverleafs at 100 yards with this load. Didn't hurt the hand too bad either. Only got two loadings from the cases though as they started to develop the "shiny ring" just above the head.
