Lyman .358 sizer

[rexherring]

Well I finally bought a good digital caliper and measured some boolits. All were as they should have been except the 38's. the were run through a Lyman .358 sizer and all measure at .357. Now I need a new sizer die and the good thing is I can re-melt the boolits. I thought of reaming out this one but decided to keep it for 9mm and .380's.

Anyone have that problem? The boolits drop out at .361 so I'll need to find a .359 or .360 for them. I hadn't noticed much accuracy problem but out of a snubby at 25 yds they were shooting o.k. and I didn't need a lot of accuracy. Now I want to use them in a lever carbine and a target model Rossi.

There can be some "spring back" of the alloy depending on the composition of the alloy. Soft alloys with higher content of lead have less spring back. Lyman sizers (and moulds for that matter) are mostly made for #2 alloy. What alloy did you use with the .38s?

I was using a 50/50 WW Pb with a little tin for my normal pistol boolits under 1000fps. All the other .45's were perfect as well as the Lee .30 170fp's.

You may want to get one that has been sized measured on a micrometer. I have an older Lyman .357 sizer die that sizes at .3575 using 85% ww and 15% pb with 2% tin added in. My micrometer is just a bit more accurate than my caliper in the tenths-of-thousandths increments. Where my caliper says .3572, the micrometer says .3575 and I trust it a little more on those smaller increments.

rexherring, You may be able to open that die by .001" or .002". Go to CASTPICS (bottom of screen) > Articles. Look for Buckshot's excellent tutorial, "How to Hone A Sizer Die." Trust me, it works.

I thought of that too but I'll just keep it for doing .380's and 9mm. I'll keep looking for a .359 or .360 die. For now I'll just tumble lube the raw boolits.

your 9 might likely be 358 too, then what?
i use 358 in both my 9's and in my 38 stuff.
each gun is a little different.
360 or 361 might not even chamber in a 38.
i know it won't in my two 357 revolvers, 359 yes, 361 no way.
even in my 41 black hawk.
412 is a no chamber, 411 glides in and 410 is too small for good accuracy.

Don't try to solve a problem that hasn't occurred.

Shoot what you got.

If they lead in the carbine - then look for another die.

I shoot .357's all the time. They work fine in everything from 2" J frame to 20" M-92.
