I have a massive supply of .357 and .38 SPEC +P brass and just bought 5,000 cast lead .358 200 gr KEITHS and would like to know if any of you guys have any favorite 200 gr loading data for .38 SPEC and .357.

I'm looking for about 900 fps in Special and 1200 in a 4 in .357.

This is for stash.

Thanks in advance for any suggestions.

I've never tried heavier than 180 grain - quick google shows some pages with info - don't know how good but

http://www.reloadammo.com/357loads.htm

Lyman lists a starting load of 7.0 grains of blue Dot for their 215 gr cast rifle bullet, with a max. of 8.7 gr, loaded at an overall length of 1.68 in.

I did once use a cast Lovern style 220 grain bullet in .357 but that was in a single shot rifle not a revolver so it won't work due to cartridge OAL.

Thanks ggiilliiee

! Oh ALL loading data is good poop! I'm 52 and started handloading when I was 11, casting bullets when I was 12.

In handloading, when loading for a cartridge bullet weight combination that you have never done before, there is only one way to do it RIGHT and that means gathering the data and experiences of others and using your common sense and experience to begin to develop your load from an interpolation of the gathered information. In some of the older Lyman and Ideal Manuals, you can take much of that data as godpel, but since the late '70s I have found that NOTHING PUBLSHED ANYWHERE should be taken for gospel. There really are no shortcuts, you got to develop your own loads for your own needs and firearms.

The data is a good starting point and that is all it is meant to be if you are a prudent hanloader.

For example I'd love to see the200 gr data because the bullets I'm loading are about 22 brinell. When you are dealing with an alloy that hard the elasticity of the bullet is not such an issue so for a given jacketed bullet weight you only have to start out about 2.0 grains down and you adjust until you get the best shooting load.

With softer lead bullets the elasticity of the bullets can drive the pressures up quickly so you have to reduce your starting loads by more and work up carefully

Thisis going to be part of my ammo stash to be used in a variety of different handguns so when I find the loads that shoot best in my two favorite Pre Mdl 27s, then I'll try them in 3 or 4 of the stainless S & Ws that I have for stash guns.

Thanks again! Please do post the 200 gr. data, the more the better!

I agree with the gas checks and would add, with the hard alloys you want to place a firm crimp so as to allow for pressure build up. They are 'slippery' compared to their jacketed counterparts, bringing two negative aspects into play. Bullet pull, and incomplete ignition. It is not as vital with the Vhit. powders as say with the very finaky H110. But if you experience the first your wheel could jam when you need it most. If you experience the later your life could end when you need it most; due to spontanious disassembly.

(I am sure you thought about it and have all under control. Just thought it should be posted for less experienced homerollers)
