I sounds like the garter spring groove was not cut properly, I would send them back. I'd caution using heavy loaders that are hard to push, if you're not careful holding the cylinder tightly when loading you could damage the crane or crane screw.

One of the Achilles heels of S&W revolvers is the crane/crane screw attachment. If you hold the revolver in your strong (shooting) hand and slam home some speedloader rounds with your weak hand, you can bend or damage the screw. Do it hard enough, and you'll send the entire crane & cylinder assembly flying off the gun. I've seen it happen to a guy with a brand-new out-of-the-box revolver. Unfortunately, the screw tip can then damage the crane, and the repair is a trip back to S&W to fit a new crane. When reloading a revolver using speedloaders (heck, even moonclips), I suggest the FBI reload, where the revolver is transferred to the weak hand, which ejects the empty rounds, then supports the open cylinder as the strong hand guides the speedloader.

FWIW, the DS-10s are popular, and those Ansac speedloaders look sexy, but I never saw the use or practicality of them. If you are going to use them, though, heed the above...

 

I'm going to send the two Ansacs back tomorrow. I'm really disappointed that they don't bother to check these before sending them out.

Here is how the rounds are positioned when loaded, pointing out and held stiffly.
Their slogan on the package is "When Speed Counts".

It takes me a good 5 seconds to get the rounds into the chambers, as I have to put my thumb and index finger around the rounds and push in on them to get them to line up. Not very speedy.

does both of the loaders do the same thing. I have been thinking about getting an ansac loader for my 617-6 but I am not sure I want to take the chance now on one of these. Have a great day

 

That sure doesn't look conducive to quick loading...

 

Just watched a couple review videos on the 10 shot ansac loaders for the 617-6 and both videos showed the ammo sitting in the loaders as they should be. Not sure what’s going on with the ones you have but I don’t think I will take a chance on getting one. Have a great day

 

Update -
TK told me they were just a distributor for the Ansac, and that the maker of the loader could give me better info as far as the issue I was having.

I sent an email and within the hour, the owner, Dave Reichle, got back to me and said he'd fix or replace the two loaders. First time he'd heard of that issue.
And he offered to pay for my shipping and even send me one of his loading blocks for the hassle.
Dave said that the Speedbeez block that I have tend to run a bit larger in the spacing than his blocks, so I'll give the blocks he has a try.

Mini-Mags (like in the pic above) seem to be more splayed out that Goldens, which are hardly splayed out at all, and load almost as easy as out of my Speedbeez.
Someone mentioned that Mini-mags have the thickest rims.
I measured some random samples of Mini-mags and Goldens, and most rims were .042".
All of the Goldens were .042", and most of the Mini-mags too, but some of the Mini-Mags ran .044" to .045". Maybe that's why some appear to lean out more than others.

 

Turns out it was the looser tolerances of the Speedbeez block that was the problem.
Using the Ansacs with either of the two Ansac blocks that Dave sent me, resulted in cartridges that were aligned as they should be.

When you are filling the Ansac blocks with cartridges, they are snug.
I tried loading Mini-Mags first as they had been the worst offender.
putting the rounds in the block resulted in some of the lube being shaved off.
Whereas with the Speedbeez, the holes for the rounds are not so snug.

Lesson, it's not a good idea to mix and match loading blocks and speedloaders between brands.
The Ansacs work great when used with the Ansac loading blocks.
