ZCast bullets are fairly new, with little info out on them, and are the least expensive commercial cast available by far. While not pretty, they are quite consistent, properly sized and (over) lubed, hence accurate.

A pair of ZCast 158 grain SWCs:

Note the messy magna lube and less than square edges. Still, they all mic'd right at .3580 and there was no leading at near max velocities, estimated ~1300-1400 FPS based on manual numbers.

For comparison, Missouri Bullet Company's ("MO," an excellent product) offering on the left, and Bulletworks ("BW," junk) on the right. MOs mic consistently at .3585 (no leading, very accurate), while the BW varies between .3550-.3570…too small and hence leaded slightly, shoulders broken down, and accuracy SUCKED!

The MO are $64/1000. The ZCast are $48/1000. 25% is nothing to sneeze at.

I took my four most accurate MO loads and loaded them with ZCast's, then at the end threw in a wildcard load using a few of my new huge stash of commie Tula Small Pistol Magnum primers.

The Tulas BTW, are copper in color (and I assume in content). Winchesters are dark brass, as are Remingtons, while CCI and Federal primers are nickel plated brass. I like the look and smoothness of seating of a non-plated primer better. The CCIs, which most folks seem to consider the gold standard in pistol primers, seated the tightest. The Tulas seated just like the Winchesters, using an RCBS hand priming tool.

The Tula packaging is identical in size, shape and type, of the Winchester box and tray, except for the label and box color of course.

The Tulas are 25% less expensive than CCI/Federal/Winchester, while Remingtons are just flat ridiculous. The Tulas functioned without a hitch.

The use of mag primers is just for availability, except for with the 296 which requires them.

**All loads were carefully developed, and you will have to work up your own. I assume no resonsibility for your loading.**


So how do the ZCast bullets shoot?

The shooting results were better than I expected after opening the box of ZCasts, 500 to a small flat rate box, 4 of those inside a medium flat rate box, for $13 postage, $109 total for 2000 bullets delivered.

Their apprearance was not a surprise. The online pictures and price had prepared me.

After my experience with the BW's, which looked bad, shot bad, and were not even cheap at $38.50/500, I was pleasantly surprised how the ZCast's functioned.

Range 50 FEET, 10 round groups, one chamber blocked, and I wish I owned a chronograph. :(

BTW, the ZCast appear to not cut the paper as cleanly, but that was only because the target backings were shot out.

Once again, the quality of the MO shines, but… with the commie primers:

By comparison, since I dumped on BW so badly, here's what I mean. :(

I was buying from Zcast before they had their website and basically sold on Gunbroker. I have found them an excellent bullet for the price that are accurate. Great test group and picture proof you have there. Some of your loads are almost what I use with great results also. I may try some of the other loads myself.:) I also use them with 38 SPL loadings and they work well there also but the bullets are on the harder side so I get some leading with them if using soft/light loads. I really like the 45 ACP RN bullets they produce for accuracy the best.
 
I've been buying his 44 Mag and 9mm cast bullets for years now. Yes, I found him selling on Gunbroker several years ago. Good hard bullets for high velocities.
I thought I was the only one who knew.
 
As I have posted before, While they aren't as "finished" as MBC they do shoot quite well for me in both 9MM (125 gr rn)and 45 ACP (200 gr rnfp and swc). For the price they make excellent blast away ammo.

Just a side, never rely on the velocity numbers provided by reloading manuals. They usually do their tests with long pressure barrels. In the real world from your revolver that 1300-1400 fps is probably much closer to only 1,100 fps, really...

The bullet on the left appears to have a lean to it ? this will kill accuracy quicker than other defects. Or it could be a camera allusion, or the crappy plywood its sitting on ?
 
Tis a shame about the bullet works. They're a local outfit and I've spoken with the lady who runs the place. Very nice lady but I'll stick to their plated bullets (subcontracted out) till I can learn more about their cast projectiles
 
I have a friend who is a commercial loader and he says Bulletworks produces a good product, which he uses despite living near MBC.

I bought 500 BW off the shelf at an LGS. IDK, but they could have been getting shuffled around for years there from shelf to shelf, banging up their edges, but that still wouldn't explain the sizing. Perhaps a bad batch.

I intend to write them at my friend's suggestion, not for a replacement, but just to let them know they may have a problem. I shot them all a while back already.
