I bought another one a few days ago.
Makes me about 3 now. ( one of which is a plain base that shoots VERY WELL )
The " numbers " on this one are about right.
Bullets fall easily from the mould, bullets are nice and round.
Nose measures .302"
G/C's are tight.
Many have very negative things to say about this bullet.
Those individuals also usually admit to trying
to shoot the bullet 2,400 fps +. I don't " hot rod " it.
I shoot it around 1,400 - 1650 fps.
It is very accurate and clean at those velocities for me.

Ben, COWW? Air cooled or water dropped?

 

[Ben]

COWW's with about 3% Linotype added, air cooled.

you snagged that one about 1 minute before I seen it.
I was like dang it,,[shrug,,, there will be others],,,, now it's more like dammit!!!
I have a 303 Brit I think I could have got that to work in just by squishing a check into place...

 

[Ben]

Sorry Fiver..........................

I have also had very good luck with this oft-maligned design. I, too, have only driven it in the 1700 fps
range with 2400 or Unique. I like the looks of it, it feeds nicely in my father's M98 with a 2 groove Springfield
and a 03A3 sporter.

Clint Eastwood said ......." A man has got to know his limitations ". True with the 413'. Once you understand the parameters of the 413' and confine yourself to velocities in those parameters , you're good to go.

One thing I'm a bit curious about ?

What was the objective of the long tapered g/c shank on this bullet by Lyman ?

 

[Brad]

Was it designed to leave room for lube and as a scraper for fouling?

 

[Ben]

You may have that one Brad ?
I don't know ? ?
This bullet certainly carries a lot of lube.

Ben

 

[Pistolero]

I'd buy Brad's theory.

[Brad]

Maybe the taper was to show the minimum acceptable size for the cherry. When the entire bullet was that size and the shank was straight it was time to retire the cherry. Then again that would imply that Lyman made moulds that cast undersized and we all know that never happened......

 

[fiver]

Ideal made slip fit gas checks, the ones I still have are taller than the Hornady checks by another 30% easily maybe 40%.

no worry's Ben, I was just happy to see it go to someone that would know what to do with it.

 

[RicinYakima]

Fiver is the winner! As long as Ideal/Lyman was making "slip on" gas checks, they used the tapered heel. Once they stopped making their own gas checks and just marketed Hornady's the went to the straight sided heel.

I promise that I'll give it a good home Fiver.

Going back 60 years........My father and everyone else called this bullet the 'Squib'. My Dad hated this bullet! He also had the Pope bullet he shot a lot. But he wanted a cast bullet for what he referred to as the "300 meter load". Before the war (that's WW2) Dad shot the M-1 military bullet with 36.4grs of HiVel #2. About 2200fps...... Popular with that era of shooters especially for 300 yards (or meters). Dad tried to duplicate that 2200fps load using the Squib. As many others found out the Squib wanted to remain a squib! 311291 accomplished my Dad's goal at 2200fps.

But why?? Let's go for the throat........ Poor design! I told my father in a spirited argument some 15 years back that I could modify the 'Squib' to shoot not only 2200 but even faster! He glared at me and spit out... "In a pig's eye!" But he gave me a mold. When your father is in his 90's you shouldn't delay proving your point. Sadly, I wasn't able too.

I agree about early Lyman checks and a taper shank. But why so long a shank????? The only thing I can figure is bullet shape. Also many back then though extended bearing surface was detrimental. What's detrimental is a long gascheck shank! I cut .100" off the base. I recut the now to big gascheck shank. I shorted the nose back to a .200" meplat (just to eyeball a better balance) It weighed about 130grs. It shot about as well an any cast I'd shot in my Savage 340 .30-30 and this gun shoots cast! All this took place at 2450fps!

There is no guarantee the original design will launch straight or even seat straight! Then try to 'push' it as in fast.... That long shank has the leverage of a pry bar to take you off the centerline! Bad crooked start equals bad at the target especially if you try 300 meters!

I think that transition from nose to front drive band is the first step in killing your high end accuracy.
that is just a built in slump groove.

My best experience has been with it in 30/06 with 6.0 grains of Bullseye. I had hoped to use it for 200 yard benchrest when I first joined the CBA in the early 1990's. In those days I was chronographing most loads, and I could not make it shoot much over 1250 f/s. Somewhere I have a B&M mould for the original Miller Squib bullet so may try those experiments again someday. Some of my shooting buddies that have 30/30 bolt guns think a lot of this bullet.

 

[Ben]

I recut the now to big gascheck shank.

How exactly did you go about doing this ?

How exactly did you go about doing this ?

I modified the cast bullets. My little lathe is setup for this and in my reloading room. I faced off the base to length I wanted and machined the upper shank remaining to .285" as they were .294" up at the top. Turn them around and shorten the nose. I'm quick and can do a bunch in not much time. I have stops to keep dimensions the same from bullet to bullet.
The last three molds I had Accurate make to my design were bullets first machined to dimension and tested (one just looked at) by machining another bullet I could modify. Not recommended for volume shooting!!!
A guy like you Ben needs a small lathe as deep as we on this forum get into this game!
