358429 ????

[GP100man]

For quite a while I read `bout the length of the 358429 being toolong for the colts & smiths ,just could`nt comprehend it being too long for the GP100 ???

UNTIL I traded for a sc Lyman & noticed rite off the front band was wider , somewhat wider !!!

I trim my brass with the Lee system to 1,285" & with this boolit it only leaves .020" to the face of the cyl . Now I have no problem trimming the brass a bit to give it some breathing room , but was just amazed at the differences .

I`ve posted on this before but I now have my PC straightened out & can post a pic ,here it is .

Lyman has let the design drift around a lot.

The ones that I have will work fine in K and L frame S&W revolvers, but NOT in the "big"
N frame guns due to a short cyl. Some variants have just enough difference to chamber
in short cyl guns, most do not.

My 358429 won't work in my Ruger GP100 crimped in the crimp groove in .357 cases. Works great in .357 in my Blackhawk and in .38 cases in every .38 I have.

Bill's right, a lot of design shift by Lyman over the years.

They fit in a Security Six.

I just bought a brand new Lyman 4-cavity from Buffalo Arms. Haven't fired it up yet, but I'm going to do a Public Service Announcement for the forum when I do and have results.

It was unscientific to be sure, but a couple of MKI eyeball checks of the mold compared with my loaded 358430 200 grainers suggest that it might work when seated to the crimp groove in my 640-1, which has a little shorter cylinder than my GP100.

So I'm cautiously optimistic about the current spec. Deer season will be the competing activity for the next few weeks, but I wanna get rolling on it for the benefit of all brains involved.

Everyone that's complaining that the boolit won't fit in their gun is forgetting one big thing, that is that the crimp groove isn't the only place you can crimp it! I'm talking about doing it the old fashioned way, crimping over the forward edge of the driving band. This will give you more room in the cylinder, but less space inside the cartridge, so you have to be careful of the load, as it could create a load over the max pressure. it can also always be loaded into 38 brass crimped in the crimp groove, should fit in any 357 that way.

The Lyman Cast Bullet Handbook data for 358429 is shown using the crimp over the front drive band.

Through the years the design of the 358429 was all over the map !
45 2.1 resolved some of the cylinder fit problems by designing his own 359429 Group Buy mold first run by CAT as a LEE 6-cavity some years ago.

And just to add a little variety to the 358429 story here are the round grease groove versions of the two bullets. The solid 358429 is from a 4 cav I purchased new in the 70's and the 358439 was purchased 2nd hand about 20 yrs ago. The dots on the meplat of the solid are my doing so that I can sort individual cavities if I choose to.

I can't remember if the picture was depicting the 359429 or the 429421, but there's a great comparison of 10 different bullets thrown by ten different moulds, mostly varying generations of Lyman. The variation was pretty eye opening.

bootsnthejeep:

My photo of the 454424s in this old thread at least shows the kind of variation that IDEAL/LYMAN has produced through the years. The 358429 and 429421 also underwent the same changes.

For my model 28 I load them in Starline 38 special +P brass over a healthy dose of 2400. I have about a bajillion warning stickers all over the boxes I store these in so I don't accidentally give them to someone else while at the range.

I love this bullet.

REMEMBER that 358429 was developed for 38 Specials in the S&W 38/44 OUTDOORSMAN...the hot number BEFORE introduction of the 357 Magnum gun or cartridge. 429421 for 44 Special antedated the 44 Magnum too.

I used the round groove version in 1979 IHMSA silhouette competition..first witha 6" S&W Mod 19..crimped in crimping groove..and a year later in a Mod. 27..crimping over front band edge.

WOW!! is what comes to mind, it looks as if there`s at least a couple of different peoples designs ,then variations on that !!!

Thanks for the pic !& what would really be nice is to know exactly when & from what cherry those molds were cut ,also when !!!

that's just lyman typicallity.
i have a couple of versions of others besides the ones mentioned abouve the 358477 has a few iterations also round/square lube groove.
noses being more rounded off and/or slightly longer,meplat different diameter.
it's amazing that they are lauded for accuracy and hunting potential, when 10 guy's could have 10 completly different versions.

[theperfessor]

Makes you wonder which version they used when they did pressure testing for their manuals.

that bullet has been around for a long time. longer then the .357 mag. it was designed for heavy loads in the .38 spl. case as in .38-44. when the .357 came along other molds were made or you have to crimp on the front band. i have crimped on the front band for over 30 years with no ill affect. in fact when i do use it .357 cases i push it deeper in the sizer and lube the crimp grove.

After the last couple days of studying my new boolits and figuring out how to load them, I'm concluding that this may be the better approach anyway. I don't own a gun with a .38 Special chamber, and this saves me from needing to acquire .38 brass, or modify .357 brass specifically for shooting this slug. I am also liking the idea of more lube farther forward, and protection of the front driving band from damage.
