When I was a young man I preferred Playboy while self indexing "my barrel" (nudge, nudge, wink, wink). Oh c'mon, SOMEONE had to be thinking along those lines or am I REALLY that demented?
Well, then, Gerry you were classified as a rich guy back then cause I used the old poor man’s playboy in the Victoria secret catalogs, lol.
Thought I was in heaven with those after advancing from the underwear section in the Sears catalogs!
As far as pcp “mags” go-
I prefer the skill saw blade tooth type rotary mags vs the spring loaded carousel mags for sure, so long as the rotary mags are wide enough to at least accept polymags w/o needing to clip the plastic tips on the polymags down. Also, rotary mags are great if the gun has a built in mag holder for them. The one downside I see with rotary manually indexed mags are the inner o rings within the mags to cause an interference fit on the Ammo. Those in time need replacing especially if you lube your pellets and the lube is not o ring friendly. Some of these mags the o rings are easy enough to change while others like the wildcat mags are not easy at all.
I have come to like the carousel spring loaded mags, especially the FX high capacity ones. So glad the aftermarket has been friendly in making fx style high capacity mags that improve over the factory models, along with the speed loaders that compliment these mag systems.
The one negative I have witnessed in some testing with Ammo, barrel liners, accuracy tests is that when using these high capacity mags in the heavier 30 cal pellets, when the mag is 2/3 empty the last few remaining pellets have had a tendency to jam, or not cycle properly. The pellet next in line hangs up and I have to tap on the mag to jossle the pellet loose and then the spring tension now pushes the pellet onward. This has since been fixed with the Orion insert along with adding his high capacity version of these mags.
ive been fortunate to also recently try new 3D printed mags by Elis5173. Nice design, unique in its own, and just like Orion’s mags and center inserts the Elis version is just as smooth with no hang ups.
Real quick, so far the best rotary mag that’s manually indexed that I own are the ones on my Hatsan Hercules Bully. Never ever a hang up, and in 30 cal they easily hold predator polymags. Gun manufacturers that design new pcp’s moving forward should take a lesson in hatsan’s design with manually indexed mags, and incorporate an anti double load feature. I can re cock my bully 25 times after a pellets been pushed into the barrel and it will never load another behind it until that pellets been shot out. I don’t understand why more manufacturers don’t incorporate that feature.
