.357 magnum, first loads!

[Drifter]

After a lot of trial and error I finally found a formula I'm really happy with!
Accurate, clean, and powerful.

I do have 1200 berrys 158 grain to use though. Anyone got a good formula for those?

(I know my bench is small but I'm starting that way )

Does that say 21 grains of h110? A bit heavy, no???

That is the starting load recommended by the powder manufacturer.

Yes, concur. I looked it up and see that the starting load is indeed 21. It's been a while since I loaded 125 GR 357 mags. That being said, I also recommend you work it up to mid to upper range. As I recall, H110 is one of those powders that like to be loaded in the upper range.

Made some plinking loads today in 38spl.
Gotta order more bullets for the 357 haha.

Any reliable published load data for a 200 LSWC should work. Use with the recommended starting load. I like clays powder.

What a great feeling! It's been over a month of reloading for me and I'm finally calming down a bit. I haven't shot this much in my life, ever!!! I've been to the range at least 8 times in the last two weeks and started selling some of my factory ammo.

I don't bother reloading .357 Magnum cases for "target" reduced loads.

I just grab the .38 SPL and shoot those.


H110 is a really good powder for pushing bullets to really fast levels. I'd opt for a jacketed bullet for those speeds as plated bullets may distort and yield poor accuracy. I have not tested this personally, just the internet hubbub and experience with really soft cast lead bullets years ago.

A chronograph really helps when developing specific loads such as subsonic or barn burners. Never knew how much I needed one until I got one.

Hey Drifter,
HP 38 is a great powder for 357's. You mentioned ordering some plinking bullets. I've got plenty of 158gr LRN that are poly coated if you are interested. They run clean and you can push them as hot as Berry's without leading. I've got .10 in them are you're welcome to a few hundred at that. PM me if you're interested.

Hey bud!
I still have about 1k berrys to go through - I was actually going to see if you had a good relatively powerful 38 load for those bullets?
