Thanks.(pardon the pun)
I have the S510XL.
Since it is an unregulated gun, it ranges between 26ft lbs and 32ft lb using 15.9 grain pellets.
It starts out at 27ft lb at 200bar, goes up to approx 32ft lb when the gun pressure is approx 160 bar and then drops down to 25ft lb as the pressure drops to 100 bar. Don't be fooled into thinking you are going to get 32ft lb over the entire fill range.
Between 200 & 100 bar I get almost 50 shots.
Depending on your extreme spread desire this may be in reality only 30 good shots as the velocits starts out at 880 fps, max of 935fps at 160 bar and drops to approx 820 fps at 100 bar.
I get an extreme spread of 20fps for approx 27-30 shots.
Never tested it on low power so can't answer that. I always shoot on full power. In fact i'd get rid of the power adjuster if I could.
Its a smashing gun, super accurate but if I was going again I would seriously consider a regulated gun or at least one that has a flatter power curve, such as some of the daystate models.
You really need to spend time with this gun to be able to accurately predict were the pellet is going to hit for each of the 50 ish shots.
Air Arms are now offering a regulated bull pup but is not avialable till May.
Regarding the bottle fill, I have a 7.5litre, 300 bar tank. It costs €7 for a fill and I get about 35 - 40 gun fills per tank.
Hope this helps.
