The SPA pumper is also on my short list. I've decided to go with a .22.
These arrived yesterday. Impressed with the size and build of them. I'll keep them in my shooting kit along with mags, lubes and filling probes.
No sorry, not yet. I've been caught up in the PCP upgrades and such. I just can't see how they wouldn't be helpful. Not only for loading pellets but also for other bench tasks hindered by knuckle draggers like me.
