Brought home a new revolver tonight. This one is a 7 round model, I think the Plus model??? Didn't get home until 10:15 tonight so all I got to do was clean it and read the manual. I have a box of 357 rounds I made up years ago for my wife's uncle who never got them. They are loaded with 4.8 grains of IMR SR7625 if memory serves. Lee cast 158 grain SWC. Looking forward to getting a chance to shoot it. It will be awhile until I get any free time but I hope it shoots as well as I've read. Who out there has or has had one and what are your thoughts?

By all means do some testing. Then share the results. I got higher velocities with the standard primers than with magnum primers.
Csparks1106 Posted - Sep 17 2017 : 19:09:19
I'll have to do some testing then. I'd like to know how much of a difference it makes with magnum primers, and yes the 550's are magnum primers
Shastaboat Posted - Sep 17 2017 : 11:53:22
CCI550 primers are fine but I have found magnum primers to be in-necessary in .357 Mag. In chronograph tests I did years ago the standard primers often shot higher velocities than the magnum primers with 2400 and other powders. I don't think the case volume is large enough to warrant mag primers.
Kosh75287 Posted - Sep 17 2017 : 09:36:53
If the CCI 550 is the small pistol magnum primer, you may not need it with 2400. I know magnum primers help with slower-burning powders like H110/W296 or IMR-4227, but they may not be necessary or 2400.
Csparks1106 Posted - Sep 16 2017 : 19:26:41
Shasta, yes I did. 158 grain though,I'm assuming that's what you meant. I used CCI 550 primers. That's what I should be using, right?
Shastaboat Posted - Sep 16 2017 : 18:52:18
So did you load 15 gr of 2400 with a 185 gr bullet? Welcome to Magnum Pistol rounds.

I loaded up some of these last night. What a difference compared to the 38 special with 3.7 grains of SR 7625. You can tell when I switched to the 357 load. Accuracy was great. My kids were busting clays at 25 yards pretty easily. They were shooting the 38 loads. My 19 year old daughter did shoot the 357 load a few times but I decided my 12 year old son didn't need to. I was afraid he would have dropped the gun.

If I need a more serious load I can up the 231 powder charge in a 357 case with Hornady 125 XTP bullets but I do most of my shooting with mild charges of 231 in 38 special cases and lead cast bullets.

Point made. I agree that the mild loads in .38 Spl cases makes for a more enjoyable day of shooting. I like to run SOME heavy loads through mine anytime I shoot it, to keep my hand in, should I ever need to use it for keeps.

I'll bet you can do some REALLY nice longer-range shooting with an 8 3/8" barreled M27! I helped a friend try to wear out a 5" M27 through high school & college, but never made a dent. It was a superb performer, even with the shorter barrel.

Yup, every time a "Dirty Harry" movie came out, UP went the price on ANY N-Frame S&W, but especially the M29s. I used to laugh/cry at the "hotdog" mentalities who'd come in and purchase a model 29, run a box & a half of ammo through it, and then want to trade it for something they could actually shoot well.

All that noise was one reason I gravitated toward .45 Colt revolvers. Their prices tended not to fluctuate much. Proper loading in a revolver built to take the extra pressure of hotter loads yielded a combination that could do anything a 6 1/2" M29 could do, except display the M29's "cool" factor.




At the time I wanted a Model 29 but couldn't find one so I settled for Model 27 (N frame 357). It had an 8 3/8" barrel. It was a great hunting pistol. I found the 357 magnum perfectly adequate for my needs. When the "L" frames hit the market I bought one and it shoots terrific. I later got a stainless version. The heavy rib underneath is a great aid in taming the recoil of a full power load although it makes carry it a little cumbersome.

I also have a Model 19 in 4" barrel for personal carry. Another great S&W.

But my all time favorite pistol is the S&W Model 17, K frame, 22 in 6" barrel. I've done just about everything with this pistol from small game hunting, bullseye competition where I qualified as a distinguish expert and hunter's pistol silouette competition. Mine was acquired in 1970 while I was in the Army and it still shoots terrific 47 years later after thousands of round put through it.

I have a can of 2400 that I got because Shasta recommended I use in my 300 Savage with cast bullets. I was planning on using it for these as well. Just picked up a brick of CCI 550 magnum primers. I need to get some brass though. I have maybe 150 pieces including a 1/2 box already loaded. I've got gobs of 38 special brass to play with. And lots of 158 grain swc's, round nose and 148 grain wad cutters.

Not to tell you how to reload, K22, but have you considered using a slower-burning propellant in the 6" barreled revolver? I like WW231 for a number of things, but it seems short-legged for .357-level loads in longer barrels. You might find that Alliant Herco or Power Pistol might give you more velocity, especially, with projectiles heavier than 125gr. Admittedly, neither of the powders I suggest will burn quite as cleanly as WW231, but the "dirty-burning" reputations of each are undeserved, especially at higher-end loads.

There's also 2400, which was used to develop the cartridge, and which I cannot get to burn completely in a 6"-barreled ANYTHING.



Yes, I used 2400 for many years and it's the go to powder for full power 357 magnum loads. In my younger days when I was a much better shot with a pistol than I am now I hunted exclusively with a revolver. I took a five point buck, several does, a few foxes, and a bunch of ground hogs with a S&W Model 27, 357 magnum, 8 3/8" barrel.

In those days I used the 140 grain Speer behind a max charge of 2400; an extremely accurate and effective combo. I enjoyed stalk hunting with a pistol; it was a lot of fun and I got fairly good at it. I kept all my game shooting at 50 yards and under which was possible in the deep woods and rolling hills of western PA. I was a discipline of Jeff Cooper's handgun hunting faternity but I couldn't get S&W 44 magnum in those days after the movie Dirty Harry; they just weren't available in my area at any price.

These days I hunt exclusivly with a rifle. My pistol shooting is confined to target practice. In my revolvers, 231 with 125 grain bullets is very accurate, mild to shoot, i.e. fun. I don't have a need for full powder loads in a pistol. In addition I get about 1,200 reloads from a can of 231 powder. If I need a more serious load I can up the 231 powder charge in a 357 case with Hornady 125 XTP bullets but I do most of my shooting with mild charges of 231 in 38 special cases and lead cast bullets.

Any quality 357 is a great pistol I have the ruger black Hawk single action 4 5/8ths barrel I think. I buy the Raineer copper plated bullets by the thousands in 125 and 158 grain.

They don't have the velocity restriction like cast or cheap Berry bullets.

I use the slower powders and burn between 9 and 18 grains of powder using the small magnum primers depending if I'm shooting the 38 special brass at +P loads or the 357 brass

38 SP brass is cheap when you buy the 500 once fired online. Shastaboat gave me probably 500 range brass once.
