Best single shot loader for Impact ‘Brilliant ‘

Can't explain why the ebay listing & youtube video disappeared, but vouch for the item working as advertised. Ordered one in .22 on 5/16 & got it a week later, $50-ish dollars I think, including shipping from the UK. Fits well & works like a charm. Have only used JSB 18.13 so far, so not sure just how heavy a pellet/slug it'll accommodate. FWIW, depth of the pellet cutout is 0.471".
 
I was thinking about ordering one? But I couldn't see why I would need one other than loading slugs or PolyMags.

Dose anyone know if .22 JSB Beast's 33 gr or the regular Polymags can fit in these single shot loaders? 

If it can only hold the same length pellets as the rotary mags? I can't see the point?
The rotary mags have no negative influence on my guns accuracy.

Yes they will fit. I’m using Polymags in 25 and Barracudas with great results that won’t fit in the side shot or FX magazine. The opening was 11.5mm wide but with a redesign he changed it to 12.8mm.

l would say that he has run out at the moment. He has been overwhelmed with the response and will be making one for the Crown too.
 
I don’t know why if some one was to run out of stock they would pull their name off eBay, along with their ad and pull the video off YouTube. Seems all he’d need to do is just say “ currently out of stock, more on the way.” 
Just do a search for his user name: squaremail. Nothing. 

I tried the tray from the Thingiverse website. A friend printed it up but it’s a really bad design. First off the tray slants down so you have to hold the pellet in place with your right hand then try and close the breach by reaching over the gun with your left. Talk about a concentration killer. The eBay tray is superior. Too bad he’s just vanished.
