I guess I learned from loading X8 moonclips of long/spindly .357 Magnums in a 627 that gravity is your friend. Muzzle down vertical reloading is second nature, despite many more prior and ongoing years of speedloading X6 moonclips of .45 ACP ball ammo - whose ease spoils you. Not into ultimate reloading speed, I have been more than satisfied with my DS-10 goodies, loaders and baseplates alike, for both my X10 617 and X8 63's. I had to go with SpeedBeez for their #351-7 to fit my new 351PD (.22 WMR). I don't know if it's me, the speedloader, or the stock rosewood grip clearance, but I feel very uncoordinated using it. I still carry a just right sized screwcap poly bottle of seven rounds as a reload - I can reload them in the dark. My HKS #51-J speedloaders work great with my 4" 651 (.22 WMR).
I do have some nicely milled Al speedloaders and loading plates - for my X8 627's. 5starfirearms.com makes a fine product, too - and they are less than the referenced Al rimfire speedloaders.
BTW, Macinaw... keep those rounds away from the adult beverages would be the best way to keep them from getting "crocked"! It works for me... I can't have anything stronger than Pepsi Max now - and, hmmm, I'm out of that - bye!

PS I have no interests in DS-10, 5starfirearms.com, or HKS - other than as a happy consumer of their products.
