lyman #311413 / 169gr spitzer

[atr]

Has anyone every had any success with this boolit for either .308 or 30-06?
I cannot get it to be consistantly accurate. The groups are all over the page
thanks

Had the mould, couldn't find a combination what worked well in either of my .308s, traded it off! The 311314 did shoot fairly well in my 30-30 Savage 340...but the 311466 shot so much better that I couldn't justify keeping both around. On the other hand, so far that old Savage has shot every boolit I've fed it as well or better than JBs.

Many, e.g. NV Curmudgeon, have had success with that CB, but you can't push it as fast as something like #311467 or #311291. E.H. Harrison of the NRA found it best to limit velocity to ~1,500 fps. Also, given #311413's lesser bearing surface, I'd make doubly sure that they're sized to fit your bore and maybe even a bit larger; .311" or perhaps even .312".

Lyman 311413 shoots real well out of several of my 06's and 308 Win.

I don't " hot rod " the 413'.

I shoot mine at 1,400 - 1,500 fps. and my Ruger # 1 stainless , 308 Win. will shoot 5 rounds in a " ragged hole " at 50 yards.



Thanks,

Ben

During CB testing of my M1A (7.62/.308) I have fired a limited number of recipes with 311413.

The best result so far was 10 rounds in 1.5" from 50 yards, iron sights. Velocity was 1752 fps average, and the bullet was water-dropped wheelweights sized .311". Charge was 26.0 H335 with no filler, sparked by the CCI #34 primer.

I have four-cavity moulds for several of the Lyman .30s, including 413, so once I isolate some good loads it'll be pretty easy to keep up the supply. 311466 seems to be my best performer to date in the M1A, but there's plenty of loading and shooting yet to be done with 413, too.

I use a 311413 mold and I limit my fps to around 1600 (this comes from using LEE's reduction formula from his first reloading manual) for my 308 and 30-06 cast loads. I can't claim to have the same accuracy as Ben but if I do my part I can match BruceB's results with that mold.

Try 20-22gr 2400. I get near MOA with it from a sporterized 03.

[beagle]

I keep the velocity below 1700 FPS and it's a shooter in my .30/06 Number 1 Ruger...especially in the HP configuration. One of my better shooting .30 bullets./beagle

[shotman]

I will agree with all above. I dont know if all molds cast a .311 .312 or not the one I have does. I size to .309 With ww you need to lube to get it through a sizer. I got good results in a Garand

[atr]

thanks for the tips guys.....Im going to give this mold one more good try ...

[Thumbcocker]

IIRC I read somewhere that this boolit is designed for squib loads to feed out of either a Krag or Springfield magazine. Col. Harrison noted that it failed at higher velocity. I have had pretty good luck with it but only up to about 1500-1600 fps.

[atr]

I think Ive been trying to push this one at too high velocity...Im getting a drift that the lower velocity works best ...so Im going to give that a try..

[atr]

here is the result of my latest effort with this mold
308 savage 99C
sized .309
35 gr of Winchester 748
50 yards,,,,,9 shots in 1.5x1.5

[HORNET]

You might want to try a different powder. I've usually found ball powders to get erratic when you reduce the loads too much below their optimum pressure threshold. Are you using any filler with that 748 load?

[flinter62]

ATR,Iload mine with 700x Vel.around 1500 fps Bullet seated just above grease ring.Flinter

[atr]

Hornet,,,
NO,,,not using any fillers in the 748 load....that powder seems to give me the best results

Ive tried 13.5 grains of Unique and the boolits scatter all over the place, again Im not using any filler with these loads but my next try will be with filler using the Unique powder load,,,,,
the best Ive been able to do with Unique is 10 rounds in 2.5"x2.5" at 50 yards

I am also considering NOT crimping the Unique load as Im wondering if my roll crimp is causing variations in pressure.....

[HORNET]

Try no crimp and seated out to lightly engrave in the rifling when chambered. Filler might still help.You could also try down around 10 gr. of that Unique. I'd try that without the filler, maybe with a pistol primer. That boolit does NOT like to go fast under most circumstances.

[Throwback]

This bullet is an old one and as the Lyman Manual and CH Harris point out it has soured many aspiring bullet casters. I use it occasionally as I can get the same results from 311041 and 311291, but it does do well in squib loads. I agree completely with Hornet. It needs to be slightly engraving the rifling to work at medium velocities. I have found best results with 14 to 16 grains of 2400 with either cartridge.

I had inconsistent results with 700X in a .30-06. I have tried Blue Dot, Bullseye, and Green Dot at one time or another in small charges. These were fine but 2400 worked best. I do not use fillers.

The nose of the 311413 is unsupported by the lands and the bullet will bend under rotational stresses causing increasing degrees of yaw as charges increase. Your charge of Unique is causing this to happen. At slow speeds of 1,400 and as low as 900 this bullet can be a real tack driver.

I'm certainly happy to find this information as I purchased a rather elderly Lyman mold for it. The owner stated that he had purchased it and a couple other molds at a farm auction in Michigan about thirty years ago and it had spent the intervening years sealed in a gallon jar. I cast about twenty boolits with it yesterday. Certainly a fine looking projectile but I had been wondering about the accuracy due to the spitzer shape. I also have a Modern Bond mold that throws a similar looking boolit but with a Plain base. I'm looking forward to testing both of them in both 30-30 and 30-40 this spring. Neil

[chuebner]

I've had pretty good results with the 311413 and a similar bullet the 311329 with 9-10 gr. Unique or 700X out of my 03A3. Velocity around 1200-1300 fps.
