Has anyone had experience with these?  Will they hold the 10g pellets without damage?  ie soft jsbs? 

Since it works on pumpmaster style, that have o-ring on bolt, was wondering if I could make them work on a 1720T, with some type of delrin block?

or the ones for Daisy Avanti?

The 760 does not have an O-ring on the bolt.  The receivers on the 760 are grooved on the front side and have a lip on the rear to hold the clip in position. 
I just tried to push a .177 bolt w/O-ring through the pellet clip and it won't fit.  760s just don't seal at the breech that well.

Thanks Bill.  and I think that ends that quest.
