Default Reloading 357 Mag?

I'm wanting to start reloading 357 Mag to lower the cost of it, and make it easier for me to get.

I had a question about the bullets though. Will cast lead cause serious leading problems, or are they fine for 357?

How are these bullets. They are kind of funky looking, but the price is really good.

I also found these.

http://www.midwayusa.com/product/640016/hornady-bullets-38-caliber-358-diameter-140-grain-lead-flat-nose-box-of-350

All I'm wanting is a decent cheap round for practice. I may want to load it hot every once in a while, but for the most part they will be loaded to normal levels. The max distance I would be shooting at is about 25 yards.

Thanks.

Don't order the "Cowboy" bullets if you are using a modern handgun. These are very soft intended to up set over low pressure and black powder loads. The hard swage bullets should be OK.
These bullets are correctly sized at .0001" above the nominal bore demension of your .357.

I cast my one bullets for the wife .357 I use a 92/6/2 alloy that is hard
enough for the high velocity .357 loads. Now if you are loading on the
high side you still may want to use jackets bullets. The cast lead loads
I load are lighter target load.

I agree with Nite, the Cowboy bullets are for very light load similar to
old school black powder loads.

Those two bullets are to soft for 357 Mag. velocity,they will work fine for 38 spec. velocity in the 800 to 900 fps. range. On revolvers you need to slug or measure the cylinder throats as they are or should be larger than the groove to groove dia. of the bore.

I've shot the 158 gr. HP bullet in the past but about 50% of them tumbled and hit the target sideways because they were to small in dia.,that was before I started casting my own several years ago.

What you need is a hard cast bullet in the 12 to 18 BHN range that fit's if you want to shoot cast lead at 357 mag. velocity.

I shot these for many years at or near max velocity in my Ruguer BH and had no leading issues. Mine actually measured .359" which is the cast bullet dia. my Ruger likes.

I looked up my notes on the bullet alloy I use mine come out in the 15-17 brinnell range.

I agree with stalker those are too soft. Here's what I've used for 357 and 38 http://www.powerbondbullets.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=PBOS&Category_ Code=38

Very reliable and fast shipping prices have gone up a bit since January but I've been very pleased with the product.

For magnum level loads with the bullets you listed? NO!
They are not cast, they are swaged. Simplistic definition: Soft lead squished into shape. Swaged bullets will definitely lead badly at anything resembling magnum velocities. My dad used the term "sewer pipe specials" to describe what what you can expect your barrel to look like if you push them fast. Mouse fart loads only, with those things.

A decent, cheap, all around cast bullet for .38 & .357 Mag:

http://www.missouribullet.com/details.php?prodId=41&category=5&secondary=10&keyw ords=
Push them fast, slow whatever, I've had good luck with them. Missouri Bullets had a great rep for CS as well. They got swamped with the big panic. Last I heard they are finally getting caught up with the demand and shipping times are back down to something reasonable.

Self serving? Sure a little, but good info nonetheless.

I think the consensus is the cold swaged lead bullets are a very bad idea for the .357. Hard cast is the way to go. I cast both 125 gr RNFP and 150 gr SWC bullets for the .38/.357 I adjust the alloy for the intended velocity. I cast them HARD for high velocity loads and NEVER have a leading problem.

Thanks guys for all the tips. I think I'll order some cast bullets from Missouri Bullet Company. I saw some bullets there I'd like to try in my 1911 too.
