I picked up a Lyman Mould 358429 SC. Came home and found out it was 170 gr. Are they to long for standard 38 special cylinders? Specifically a Model 14 S&W?

The bullet was designed for .38 Spl.

You'll need Small handles, as Jack said below. Unfortunately the Lyman handles sold currently and marked Small are really Large, at least the ones I have seen since they stopped making the single cavity handles.

You can find these on the auction sites, but you'll pay at least as much as new current handles.

Thats good news. Now I have to find handles. The original box says 'use with handles marked SMALL'. Are there any difference btween the current 2 cavity handles the handles that I need for this mould?

The current large handles won't fit. We tried. On the other hand, they made them for a century so the old small handles aren't had to find. There's several on eBay now.

Are they to long for standard 38 special cylinders? Specifically a Model 14 S&W? If they are, just crimp over the front driving band. This is what I have to do when loading these in my Mod 27 Smith in 357 mag brass. In my Mod 19, the cyl. is longer, so I crimp in the normal place with the same load. I believe this bullet was designed by Keith to load near-357 pressure loads in 38 Spec brass for use in 357 Magnum guns. One must be careful doing this if he has 38's laying around, though!

Sounds like a reason to own some +P+ headstamped .38 special brass, and to keep them segregated and only for those hot loads. Personally, I keep to .357 brass in .357 chambers to be sure I don't get the lead build-up beyond the mouth of .38 Special cases that can interfere with chambering a .357 round and cause high pressure.

Me, too. I have experimented with them (358429 bullet) in my M27, though. The difference in OAL between the load in 38 brass crimped in the groove and the 357 brass crimped over the top driving band is only about .015 in. or less. Not too much more "jump" to the forcing cone. Of course, never loaded full 357 loads in 38 brass, but backed off 10 or 15% & worked up.

Lyman suggests the 358429 SWC be used for silhouette shooting. In their "Pistols and Revolvers Handbook" the test cartridges using this bullet was loaded to an OAL of 1.537" which should just fit in your K38 cylinder with a little "wiggle" room to spare. Lyman recommends that .38 Special max load velocities with this bullet be kept under 850 fps. Best wishes.
