Benji 392. Best number of pumps?

[FNG54]

8 pumps gets 18+ fpe with 25 gr JSB's.
It takes 10 pumps to break 18 fpe with the 14.3 CPHP.

Haven't seen a good .20 cal clean barrel that didn't love the 13.7 JSB's so that would be my starting point. Baracuda/AKA Kodiak, FTT/AKA Beeman FTS, Crosman Premeir and Benjamin Cylindricals are all good candidates. If your application is back yard 15 yard max you don't need anyhtibng over 4 pumps. Try them all and your particular application will make one shine brighter.
In the JSB .22 you have 14.3, 15.9 & 18.1 which can all be good as well as Baracuda, FTT and the Premier 14.3. Better selection ion .22 but good still in 5MM. Sure wish we could still get H&N Red Box Dan ammo. That was a shortlived pellet and they worked great. H&N made them and they were replaced by the American made 14.3 Premier in the early 90's.

I just got a tin of the 13.7 in, so I will give them a try.  I also have some Polymags I want to shoot, I needed to fill out my 4 tin order so I basically got them free...

Both my Dan and 392 are sighted in at 25yards with 5 pumps. The POA for 5 pumps at 25 yds works out to be about the same as 8 pumps at 50 yards. For .20 cal my Dan likes the Webly & Scott Accupell best for accuracy. The EunJin .20 cal heavy is surprisingly accurate out to 30 yds. I don't hunt but I do some occasional pesting around the homestead. I bought the 392 for pesting duty but more often than not the Dan gets the honors and does very well in that role. My 392 is a capable weapon in it's own right and shoots JSBs, H&Ns, and RWSs all very well. When I want to bust something in spectacular style the 392 with a EunJin pellet never disappoints.

The Benjis and Dans always were and still are killing machines. No mods are necessary to take most of the small critters you'll encounter on the average homestead.

amen. dans and cylindricals have always gone well together.

5 pumps. all that is needed. my sheridan is the same. shoots mid 500s. learn trajectory and lay down the law.

I agree with this statement, and I'll add my own opinion.

From 20 yards or less, I fell that a minimum of 8 FPE of muzzle energy is sufficient for a human kill, as long as you can accurately hit head shots or vital organs (heart/lung).

On my 392, 5 pumps used to give me about 550 fps or 10.5 FPE with JSB Exacts 15.89 gr pellets. 5 pumps also proved the best accuracy for my gun.

Recently, I had to replace the valve in my gun, which lowered the overall velocity by about 40 fps on any number of pumps. Now I need to pump my gun 6 times to get 550 fps with those same pellets. It shoots as good as ever, just lower velocity.

Velocity may increase as I break in the new valve, but I doubt.

All shots I take are with the same number of pumps, even when target practicing, in order to maintain consistency.

that's an unfortunate typo.  you might want to add an e to the end of one of your words there

Great catch   I was just noticing the 7 year gap between posts myself. That and sparrows must be wearing kevlar these days.
