Anyone loading .357 mag loads with Lyman's 358429?

[Bula]

I'm currently casting the 358156 Gas checked .358 SWC (dropping at 162 gr) But I like the idea of a heavier, non gas checked Keith design. I'm shooting these from a 4" GP100 and a 6" 686-no dash (my newest toy )

I'd like to know how the bullet performs, how fast can you push'em and the best powders for the job. I like 2400 for heavy and Unique for mid level 357 mag loads.

Thanks in advance.

Bula,

Using 13.5gr of 2400 with the 358429 bullet in my 6" 686.

For the last 10 years or so I havn't been casting my own bullets. But I've been using some dandy 358429 cast SWCs from Leadheads Bullets in St. John, Kansas. Leadheads calls them "358-168" but they appear identical to the bullets from my Lyman 358429 mold.
At any rate, they're not all that much heavier than the ones you're dropping from your 358156 mold - they weigh 167.5 grains, including the lube. I put them over either 13.0 grains of 2400 or 7.0 grains of Unique in 357 Magnum cases. I use them in my .38 Specials over 4.6 grains of Unique. They work well for me in +P .38 Special loads too. For the +P .38 Special loads I use magnum primers and HS-6 powder. I'm hesitant to state how much HS-6 powder I'm using because it's a little bit more than is listed in the manuals nowadays, and though it's fine in my .38 Specials, it might not be prudent in someone else's.

Bula--I've been shooting that bullet over 35 years out of various .357's. Currently out of a Ruger gp 100 6" bbl. I've gotten excellent accuracy with max loads using all the slow burners ie. 2400,296, h110, AA9 and Blue Dot. Leading is not a problem, all these loads run 1300 fps roughly out of a 6 " barrel. I personaly have never seen the need for gas checked bullets in any of the magnum pistol cartridges. I have loaded plain based bullets in both the .357 and .44 mag with no problems.
