FAC Air rifles?

[Basemetal]

Do you know what power the rifle you tried was? I've seen some 16 ft lbs which makes little sense to me. 40 ft lbs was where I was looking.

But I'll have a chat with the constables about .22LR for pest control first anyhoo.

[Cones]

These go up to 80ft/lb

Mines running at 36 ft lbs and it doesn't deliver a corresponding 3 x jump in performance.

Not usable performance anyway.

I think it was supposed to be about 30 ft lbs. Also chronographed another one a couple of years back for a friend - it fell well short of the claimed power, was sent back, "fixed" and still didn't come near the advertised power. Can't remember the specific figures, I'm afraid.

I think I'd have a serious look at the 17HMR if I were in the market - the one thing I don't like about the .22LR is the tendency to ricochet at almost any angle (get a box of tracers sometime and scare yourself when you look at how they ricochet from seemingly impossible angles).

If they'll give you a rimfire I still think that's your best bet.

And just one addition though/comment... (for now )

Before we all get too hung up on the ft lbs question - I've shot rabbits with a .22 air rifle (12 ft lbs) and had them drop on the spot. At the other end of the spectrum I shot one with my .22-250 a couple of weeks ago (approx 1650 ft lbs) and it ran for 20 yards before expiring (it was a clean chest shot, too).

You're lucky it went down before it reached you.

Never trust the man wearing a stetson and about to mount a giant rabbit.

No good will come of it.

Mark my words...

Understood. The main drivers for more muzzle energy for me are 10-15 yards more range and a flatter trajectory for more reliable point of impact. With just 12 ftlb I wouldn't take any shot other than a clear profile headshot, usually at 20 yards. Mr Bugs seems to know this now and lurk at about 35 yards

I current use 15gn Crossman Powapell (the pointy ones) and while they widen the group very slightly over the rounded Accupel, all the head shots I've checked have penetrated fully. I tried the .22 wadcutter (Vermipell -not a name that will catch on!) and found them unacceptable at 25 yards -good just to 15 yards and coup de grace in my opinion. (I determined the groupings on targets, I hasten to add).

I wonder if .177 might be a simpler solution for trajectory?

With a 12 ft lb rifle (Tachi'd at 11.6) I get about a 3" drop at 30 yards when zeroed for 20 yards with a 15grain pellet coming out around 560 fps. Beyond 30 yards I wouldn't attempt reliable kills on rabbits.

I am amazed you get a 3" drop over that range. My Rapid 7 (MK1) is zeroed at 30 yards. Pushing out 11.6 ft lb and using Acupells. At 20 yards it shoots 0.5 inches high and at 35 yards 0.5 inches low. At 40 yards it is 1.5 inches low.

Most of the time for about 18 yards out to 35 yards I don't make much allowance for pellet drop and I don't miss much. Having said that I usually only take the shot if I am pretty certain to hit.

At the risk of chucking a cat amongst the pigeons, I use a .20 calibre Theoben Evolution (12fpe). It shoots noticeably flatter than a .22, but still retains plenty of energy. Pellet choice is more limited and some pellets offered in .20 are nearly as heavy as the .22 equivalent, but my gun gets on very well with H&N FTT's (11.4gn). Some have said that it's the ideal calibre in 12fpe, but there lies a big pit of entrenched opinions

Great - now I've got the Donnie Darko theme running through my head...

Same set up and pellets as me! I noticed the drop off is much greater than .177, but then that is petty obvious what with a ligter pellet etc. I had a go on chairgun or whaever its called last night, bu I'm not sure if I filled it all out correctly. It gave me a sheet with different pellet impacts at various ranges, the time it takes to cover that distance and the power at the point of impact.

I'm surprised how little it asks information wise, thetypeof r*ifle isn't mentioned at all!

Why would it be, the speed measurement is done once the pellet has left the barrel, so the rifle has no further effect on it, its down to physics after that. Am I missing something?

I believe that the rifle does have an effect. There are variables in the barrels used, is there any choking, the degree of rifling? Pellets get squeezed or spin at different rates. These can effect what happens to the pellet after it has left the barrel. The chrono measures the speed just after the pellet has left the barrel and does not measure down range performance.
