54 Lubed with gas check. Lyman #224415. Hornady gas check. Wheel weight with about 1% tin added. Sized at .225. I went from 6.5 - 9.0 grs in .5 gr increments. 8.0 giving the best groups. Crony is not working again. Yes I used a lee factory crimp die. I'll try without that. I did chamfer heavily. I have no idea how to fit a bullet to the throat. Yes the lube grooves are squeezed in, but the driving bands are sharp. I didn't clean the barrel at all, is that important?

M die? Good idea, but I have gotten good results plenty of times over the years just by putting a heavy chamfer in the case mouth. I would sort by weighing too, if sub-MOA accuracy is the goal.

One thing I would stop doing is crimping the bullets, if that's what I see in the pics. Some like to crimp, I don't.

How well does that bullet fit the throat in your rifle? Mastering all the variables I asked about initially won't give gilt edged accuracy if they are a lousy fit in the rifle's throat.

Some of the bullets in the one pic look like the driving bands aren't filled out, and some show lopsided sizing (lube grooves squeezed semi-shut in places). Could be a trick of the light, I suppose. But if such anomalies exist in a .22 bullet, they cause more erratic performance than similar defects do in a big bullet- based on a percentage of gross bullet weight variation/unbalance.

Still in all, 2"@100Yds. ain't all that bad. Getting jacketed bullet "benchrest" accuracy with cast .22 stuff requires strict attention to the minutiae.


All of the above for sure.I did notice some minor nose deformity unless that's just my monitor. The proper matching top punch would help as well..But considering all the variables 2" is not bad.

I have the right top punch, according to lyman.

I think I can do better than 2.25" groups100. Am I asking too much?

I have several recommended top punches that still tend to ding up the bullets so a little trick I use is pinch off a small piece of paper towel fold it a few times,then wet it and push it up in the top punch.After a few bullets it will conform to any deviation and won't leave ring marks.Maybe a tad anal but I like clean looks as well.

Nothing wrong with a 2" group for hunting but yes you could probably tighten groups experimenting with different powders,alloy,fillers and seating depth..I agree with Gnoahhh as well, crimping isn't always necessary.

Good job overall for your first go round.. smile

Determine throat diameter with a chamber cast- either with Cerrosafe (follow directions religiously), or via a pound cast with a soft lead slug. Size the bullet to .0005" under throat diameter regardless of what the groove diameter is. Inside diameter of sized cartridge case sized accordingly so as not to alter bullet diameter when seating.

A trick I use to mate top punches to bullet noses is to put a dab of thickened epoxy in the punch and drop it onto the bullet while partially sticking out of the sizing die. (Don't forget the release agent on the nose of the bullet!) Wipe off any squeeze out and let sit until epoxy hardens. Presto, a custom top punch. I turn my own top punches on my lathe, and since I don't want to be so anal as to machine a perfect cavity to match a particular bullet nose, I simply hog them out oversize and then do the epoxy trick.

Good idea. I'll be trying this.

I cast in my garage with the door up and a fan running so I'm trying to make it until warmer weather.

I've been playing with a new bullet for my 40-65. It's a 425gr Steve Brooks mold.

Cast a bunch of 90swc .314" for my 32 H&R yesterday.
Loaded them over 5.0gr AA5 and tried them out today.

[Linked Image]

They shoot good, all touching at 10yd if I do my part, and show no signs of leading. Interestingly enough I shot them into wet catalogs and they penetrated 6.5" in a straight line and could be reloaded. I think they should work fine for rabbits and fox or coyotes. [Linked Image]

Kid, is that flame cutting on the base of the recovered bullet, or just impact damage? Hard to tell in the pic.

If it's flame cutting, you could beagle that mold to bump the diameter up a thou or two, and see if that cures it.

They are slightly bevel based and drop from the mold at .315. Inspection upon recovery showed no sign of cutting with minor deformation from impact. My pistol slugs .314 and the throats are a uniform .3145. Sure is fun to shoot.

Kid,I cast the same 90 gr. SWC bullet as well but I shoot it in all my rifles. Sized to .314" for 7.62 x 39 and 54r.sized to .311" for 30-30 an 300 Sav. but it will work just as well in any 30 Cal.rifles.

I cast the bullets from pure lead usually but anything slightly harder alloy with 1/4 to 1/3 WW to pure will work fine as well. Using 3.0 grs. Max. of Bullseye in the X39 and 3.0 to 3.5 grs. Bullseye for all other calibers MV runs between 850 to 1100 fps. with the listed charge weights.

You should be able to hold 2" or less groups at 50 yds. fairly easy.

I tried the Lee 90 swc for the first time this morning,out of my single six. Four grains of Unique was the first load I tested. I about fell over when I looked at the target - two touching, one three quarters away. I went back to the bench and shot the same load again. Same thing, honest one inch group. I tried up to 4.5 grains but the Lee seemed to like 4 grains best. Great plinking load right out the gate.

Ran a few heavies for the '86 Win 45/90 lever gun. Pushing its envelope a tad with this Lyman 457121 PH at 480 grs but it does shoot well for a 20 twist although having to crimp over the last band for OAL.Lots of firepower on demand with a full mag..

After way too long away from the melting pot, I finally got around to casting some on the 4th of July.

About 280 from an LBT WFN .512" that will go about 430 grs. for the .500 Linebaugh. A few over 500 from a Lyman 257420CW .257" that will weight out about 75 grs. when sized, GC'd, and lubed for the .25-20 Win. And a little over 150 from an LBT LFN .413" that will go about 385 grs for the .405 Win.
