Your Favorite Magnum Load?

[gwpercle]

This is my "pet" 357 magnum load , developed in 1971 for a new Ruger Blackhawk , 6 1/2" bbl. length
155 grain cast SWC w/ gas check , Lyman # 358156
sized to .358"
7.0 grains Unique @ 1098 fps w/ 6 1/2" bbl.

This is a good accurate load . Because of the gas check , the bullet doesn't have to be that hard ...
I still have the Blackhawk , we still go dancing and she's still in good tight shape ... this load will not beat a gun to death .

For years I shot that 7.0 grs of Unique using the Keith 173gr swc , Lyman 358429. I shot it out of my first model 19 . A very accurate load with plenty of " hitting " power . I got that load after reading about a bowling pin match in the 70's in east texas . Some Louisiana state troopers came to the match using that load , shooting model 19's w/ 6" barrels . It was reported they had bowling pins flying all over the place . Regards Paul

I got that load out of the new 1970 Speer #8 Loading Manual ...
It was the Starting Load !
You don't want to know what the maximum load was ...

Actually Gary , I have Speer #8 . I have never had a problem with the starting loads in that manual . Surprisingly , some of the loads in that manual are only equal to what we have today and some are less than quoted today , and yes some are unacceptable . Regards Paul

A few years ago I was out of H-110, so I tried IMR 4227 with a Hornady 158 gr. XTP. It worked out so well, it's been my "go to" .357 Magnum load since.

You would be BRAVE to ask and use internet data. Always use a current manual for your loads. Manuals list them from mild to wild.

My std 357 load is my cast 168 gr SWC pushed by #2400. not telling ya the charge.......What's good in mine may be bad in yours.

12.0-13.0grs 2400, under 158gr bullets. 12.0-12.5 for powder coated cast, 13.0-13.5 for jacketed bullets.

158 gr. SWC, 15 grs. 2400. 2 1/2-6 1/2 in. barrels. I don't shoot many in "K" frame guns but they work great in heavier guns. I had the two first Marlin .357 rifles sold in my area and that load didn't shoot worth 2 cents in them. Larry

Larry , I have had marlin rifles in the past and always had to use " over size " cast bullets for optimum accuracy . I wouldn't be surprised if those marlin rifles in 357 needed a cast bullet of .359-.360 in diameter to fill the groove diameter of the barrel . Regards Paul

14 gr. 2400 for 158-173 gr cast boolits.(Mostly the Lee 158 RNF which drops at 160 with my alloy.)

I have Model 19s, and I don't want to keep two .357 loads sitting around - one for the 19s and another for my heavier-duty revolvers. My preference is 13 grains of 2400 with the 358156 bullet (165 grains), and has been for so long I forget who told me about it and when. Standard primers and a good, firm crimp. It's more accurate in every 357 I've ever shot than I can hold, it's plenty powerful for my uses, and it's not vicious in a Model 19, like a full-charge of H110 or W296. IMO.

From time to time I've used the same charge with a couple of other .357 cast bullets when they were what I had on hand, but the 358156 is the one I can count on for accuracy.

The .357 makes a lot of sense to me. Works well in carbines and revolver. Capable of fine accuracy, economical of powder and shot, easy to reload and no detachable magazines either. Neither revolvers or lever guns throw their brass far. I have guns in other loadings but the .357s will be the last to go.

I have three loads that I like.

158 grain XTP hollow point over 16.7 grains of H110. Remington cases and a magnum primer. I have chronographed this load at 1750 FPS out of my Marlin rifle. This load out of a carbine has worked well on a number of deer. I have never recovered a bullet as they all passed through. This load is very accurate in the Marlin. It wears a red dot and I have old eyes but have still seen 1.5" groups at 100. I am a decent shot but no Joe Benner. Go figure.

158 grain RCBS semi wadcutter gas check over 15.9 grains of H110. This shoots to the same point of aim as the above load in the Marlin. Accuracy is about the same also. I am most definitely NOT a master bullet caster and I have 68 year old eyes.

Finally I shoot a 148 grain HBWC over 3.0 grains of 700X. I use this mainly for revolver practice but the Marlin feeds it with total reliability. The problem with this load in the Marlin is it shoots low and to the left.

As you can probably guess, the Marlin is a keeper.

What I am going to do now that deer season is over is develop a load that duplicates the 125 grain 357 Golden Saber. Not sure why I have not gotten to this before as the Golden Sabre shoot great in all my revolvers.

I no longer load any magnum handgun cartridges, but did load them with cast bullets for forty years or so. My favorite .357 magnum load was a mild magnum load, but accurate and not hard on the shooter. I used the Hensley & Gibbs #51 design, about 160 grs. in wheelweight alloy sized in a .358" die. I loaded 12 grs. #2400 and either a CCI 500 or CCI 550 magnum primer. The magnum primer made the load slightly more accurate but the standard primer is fine. Muzzle velocity from a 6" Python was about 1100 fps. 14 grs. 296/ H110 will give about the same muzzle velocity and good accuracy, but has that offensive fireball and blast that's much reduced when using #2400.

NOE 160 WFN cast from ww + 2% tin and 12.5 gr WC 820.

I broke a 586 no dash hammer bushing and recoil shield firing published reload data. S&W replaced the frame and reassembled using all my old parts. I don't go hot with anything anymore. I recently came across a nice 66 BB 3" with a set back nose bushing but I passed it up for above reasons.

I use IMR4227 powder with a 125 gr JHP. Very accurate in a number of revolvers. Work up to the best groups.

Had a 6 inch M19 with a scope that would group at nicely 100 yards. That was for deer. Used H110 with a 180 Hornady JHP.
