Pellet Power Over Fps


Recommended Posts

Hw 100 in 177

8.4 g =770 fps

10 .4 g = 710 fps

Jsb monsters at 13.4 g 620 fps

Is that about the speed of your guns with .22 cal

They must have some hitting power at shorter ranges

Sure fire kill for rats ?

Just out of interest what's your thoughts

As a new guy I thought that .22 would be better for hunting, I know that .177 fly flatter but if they both hit the target a .22 must hit harder ?.

If both pellets arrive at the target doing lets say 9ftlbs, how can one "hit harder" than the other? The striking force is the same, the .177 will penetrate further as it has a smaller surface area and is travelling faster, so may not dump all its energy into the target, but we are talking about shooting a rabbit with an air rifle, not a deer @ 250 yards and discussing the merits of say a .243 v .308 using expanding ammunition, a head or neck shot on a rabbit or similar quarry will cause instant death, irrespective of calibre.

Hello Charlie

You say if both hit the target at say 9ftlbs but I am saying that the .22 would not be the same hit as a .177 because of it's bulk unless you mean a .177 of the same bulk weight. Is that what you mean. If that is the case would the .177 fly as straight as the lighter pellet and if so why bother having .22 ?.

BTW I thought that say a HW100 in .177 would make mince meat out of pigeons and rabbits ?.

They were absolute mustard through my hw 77, deadly, the 99s did shoot them ok but not as well as the 77, but of course yours may well be different, going to try them in .22 in the new 99s.

That is good to Know as I have a HW 77.

Like charlie said both will hit the same

 

If the .22 pellet has more weight how can that be, or are you saying both pellets of the same weight ?. Just asking as I can see that the .177 seems to have a stronger following than I thought. Have I missed the point. are we saying that if a .177 was loaded with the same weight pellet that the impact would be the same so you could use a .177 instead of having one of each ?.

9ft/lb of energy when you hit your target whether its .177 ,.22 or a bag of feather , is 9ft\lb

You might be getting mixed up with surface area of a pellet

Ditto to above, if i throw a house brick at your chest from 35 yds and it hits you with a force of 9 ft/lbs (figures sake) and then i throw half a brick the same distance to hit you with 9ft/lbs of kinetic energy - what is the difference ?

 

1, Trajectory

2, Velocity

 

With a brick :laugh:
