Yeah hindsight LOL ;D   Been there too many times LOL

I did notice, using Airhogs fill calculator, every 100psi capacity over the 3000 makes a big difference. But the thing I read about the 3300psi al tank is you need to remind the fill guy you have a 3300 tank otherwise they tend to assume it's just 3000 like most al tanks.  I was guestimating 190cc for my air tube for the calculations and 2900/1900 refill levels.

I really like your carbine.  If cost was no object I'd get a 410 carbine with the side lever, adjustable power, and walnut stock (and a nice cf tank setup with the works LOL).  I have a used but great condition 410 bolt action non-carbine with beech stock coming soon, and for the money really can't complain at all.  Now just need a way to get it filled, without making my life any more complicated. The nice thing is the nearest scuba shop is only 5 minutes away, with another one almost as close but I haven't been there yet--a benefit of living near the coast : )

BTW thanks Gene for running this forum (correct me if you don't), I've been around lookin' in for a few months, it's a lot of help and have some good folks around.  Hope this is not too off topic...Is there any way to change my forum ID without starting over?  I'm BobRI on the yellow and like to use the same here if possible, not a big deal either way though.

Bob, the airtube in you ERB is 314cc , the Classic has a 242cc tube and the carbine has a 181cc tube. kirby

Gene, If the scuba dealer fills your 80cf tank to 3200psi, which he should without any problems (could go to 3300psi mine does on my 88cf tank) ; then using the calculator on Airhog's sight , with you filling to 2500psi (my sweetspot with my carbines) and shooting down to 1500psi , before refilling (about 50 shots) you would get 40 full fills . On the other hand if you're filling to 2900 psi and shooting down to 1500psi, then you would only get 12 full fills. So by filling to the lower pressure fill of 2500 , you would get 40 (fills) X50 (shots)= 2000 shots per scuba tank fill and  with the higher pressure fill you would get , 70x12 +840 shots per scuba tank fill. That's with a 181cc carbine tank. kirby

Thanks for those numbers David.  I couldn't find them when I looked. Finally decided to get a cheapo Kingman fill yoke at Pyramyd for $70 and a new al 80cf tank locally for $190. The up front cost on the new tank is more than the $104 used one, but the new one comes with 10 fills and fresh hydro and visual tests, so bottom line was only a few bucks more than buying used here. And resale value should be higher if I want to get rid of it or trade up. And the guy was willing to fill to 3200psi. Got a Chrony F1 too while I was at it, figure it'd be a big help with working out my fill pressures.
