Lyman 311 413 data

[cdet69]

Anyone have load data for a Lyman 311 413 bullet. I am using 5744. sr 4759 and 2400 for powders. Also COAL would be helpfull to. I plan on using it in a 30-06. Thanks

16.0 grs. of 2400 works for me , the squib boolit starts loosing accuracy after `bout 1600 fps or so.

Do some "searches" on it you`ll find some info .

Any idea on what the coal load in a 30-06 should be?

Makes no difference in pressure. The mag length and your gun's throat are what
will tend to control LOA. LOA is a factor in pressure in small pistol cartridges, much, much
less of an issue with a big case like .30-06. Make sure that a dummy round will chamber
without jamming into the rifling and will extract intact without leaving a boolit stuck in
the throat. Both of these things can and will happen with a LOA too long for the
particular rifle. No two alike.

I have had good results with this boolit over 10 gr of Unique and 16 gr 2400. Several
sources report great accy at moderate vel (like the above two loads) but poor accy if
pushed too fast. Personally, I cannot verify this, don't push cast fast in rifles.

i concur with the above.
i use this design in my spanish 1916 7.62 maus.
and it don't like to be ran faster than 1600 fps, load is easy to remember ,,,16-24-16.
well i guess the 16-24 part can go for any 30-32 cal rifle load per Mr, Ed Harris.
have a good sunday.:evil::coffee::twisted:

I was reading an older NRA manual and it said that the Lyman 311-413 was a very velocity sensitive bullet. It was also a great failure for Lyman because of the bad reputation it developed.

The 311413 was the second mould I acquired when I started casting for .30 Cal. rifles. Being a "newby" (to casting for CF rifles) at the time, I attempted drive it at the same velocities as I was obtaining with the ol' reliable 311291 (173 gr. RN) with absolutely miserable results. .308, .30-30, .30-06...didn't make a bit of difference; even my 50-yd. groups looked like buckshot patterns.

Was ready the "retire" the mould and remelt all 311413s I had on the shelf when I picked up on a thread here discussing the Ed Harris/2400 loads. Loaded up a few .30-30s for my Savage 340 and "WOW!"...first three shots (off sandbags) went into 3/4" at 50 yds.

For a larger case like the '06, though, I suspect you might get better get more consistent ignition with a bulkier powder...like 5744...that would fill more of the case volume.

I have used it over 34 grains of WW 748 for about 2000 fps in a 28 inch 30-40 with decent accuracy, but I got much better results with the 311-291 and the 311-644, so it became an also ran. I only shot it over 15 grains of Unique in my 30-06 and did not try it for accuracy--just as a plinker, so I have little experience in that caliber. It does shoot well in my Springfield 325 30-30 bolt gun though. 17.5 grains of 2400 will shoot groups equal to or under factory stuff.

Lyman's 311413 is one of several versions of the "Squib" bullet named after the designer, but made by several companies. A lot of folks have given up casting because of this bullet. I don't know what it is about it, the center of gravity or what, but I have a couple different versions, a Belding and Mull 311169 and a George Hensley 20-312-170, and try as I might, they don't work well above 1600 and even at that speed accuracy is so-so, generally around 2" out of my Krags. I've tried harder alloys, slower powders, oven heat treating, and other tricks to try to get it to shoot faster, with accuracy. It's a frustrating exercise. But, at 1300-1550 it will often shoot one hole groups for you. So try about 13gr of that 2400 for your first loads and you'll probably get a nice group as a reward.

The 311413 is strictly a slow-speed boolit design but its awesome when you keep the boolit within 1600fps. At that speed, the heavier weight will still roll rabbits.

Thirty plus years ago I used the 311413 in my Schmidt-Rubin for 100yd. High-power. This was a very accurate bullet. Around half an inch at 50 yds from a rest. Made Swiss cases from .284 Winchester. Nineteen grs 4759 sparked by a Remington 9 1/2 Primer. Bullet seated for .005 jump. NO FILLER.....................
