.177 AA Field = 6 lbs !! Borderline!

Obviously select the desired pellet.

On the POI graph which is what I normally look at....right mouse click, go down to Energy and select Energy....then that gives you a graph of energy vs distance.

Result is .22 retains its energy better at distance....
However the .177s velocity has dropped from 825 to 575 fts vs .22s 575 to 475 fts........leading to the .177s flatter trajectory at these distances (I know there is more to it than this!!!)

The .22 drops 3 1/2 inches in the next 5 yards vs .177 2 inches drop.

If the warren by a hedge... Is there a run along the hedge, and whats the current thinking on using snares in such a location? Never been convinced by them myself, but if they'd work anywhere then this is the kind of place?

1, Thats was my gut feeling.
2, Cheers. I know I had done it before but could not find it in the options
3, Yeh .177 flater & faster but .22 carries more energy. Why does .20 not take off lol?

.20 Just doen't have the pellet choice, a bit like .17Hmr !!!

No what would be nice would be an FAC air rated .25 !!!

Probably running 80ftlbs or there abouts............ do you think I could get my BSA Meteor to do that!

Er yeh with a car suspension spring lol. .20 would have the pellet choice if more guns were made. .25 would carry some serious power at the longer ranges but the hold over would be high. Why not .22 at 80ftlb? My .22 is very easy to adjust the power on but at the higher (will only go to about 15 ish anyway without mods) end gets less consistant. Set at the legal limit it is within 3 feet sec over a 60 shot string as long as the max presure i use is 185bar but if I use the 200 its specked for its much less consistant till the presure drops.

i will see if i can get arranged to work at 25 to 35 m for more reliable hits
bales is a good idea
prone shooting ,sandbag rest as gun is underlever
cammo sorted
invisible silent movement and hidenseek practised
the need for quiet is noted
it is a gun mounted lamp but seems very bright
there are some lumps in the landscape near the warren which is in a hedge with salad both sides i will see if they can give a good zone backstop noted
luckily the warren is well away from the boundary and footpath

Oh for interest the terminal distance is about 400m if angled for max distance.
Not that you would get that whilst actualy taking a shot unless over the brow of a hill / or up to a roof ridge line at a pigeon like some..........

that really puts the backstop thing into perspective
getting familar with the site before the gun comes out will be done
i have decided that 25 m should be possible and is a good idea ,i used to get very close when i used a customised vulcan many years ago ,a 5 p target at 50 is not beyond me with this gun but at 25 it is reliable and a lot more terminal energy is available so sneaky hidey close work is in order .
thanks folks loads of good advice

A Vulcan bomber sounds a bit extreme for bunny control....

a 10mgton bomb clears a warren ever so fast but wilts the salad

Would need a 21 degree up angle to achive that distance (381 yards)
with a terminal power of .25 ftlb lol


get a copy of that prog (chairgun its free). You can then set your kill zone size & look at optimum min / max zero ranges allowing a dead on aim over a long range (12.9 to 30 yards aprox for your set up & a 1/2 inch kill zone)

a flatish line over a reasonable variety of ranges that cover the kz is very useful and avoids fiddling about if time is of the essence but the mil dot works well to adjust for the arc
the terminal balistic energy,kill target size ratio thing is very educational and i know why 25 m will be better than 50 m and closer still would be ok if i can be sneaky enough
the bunnies are new to being shot so maybe i can stay ahead of them on the learning curve

armed recon ,
hides need to be planned
when i work out the questions i will be back
too many cats and other critters to think of snares but there are places it would work
gaining several feet up as a fire position would be good both to see flopsy in the salad and to be able to have a backstop in the flat bits
the cover is not where it is needed for me but it is for them ,bunny clever and bunny shy of humans
i did have some crosshair moments from behind a log with many bunnies as they set out but no clean shot to head as they were all bum towards me as they pottered about or there was no safe backstop
prone in a hollow filling with rain and dissolving sheep crap was invisible with a bit of scrim but flopsy was not out in the rain
advice please

are paths better than the warren forecourt or picnic area ?
would a dry drain with a warren in one bank and salad up the other side be a good place to do some trimming to get a plant free kz ?

Long net set 8-10yds from their burrows/thick cover.
Drive them into it on a wet dark windy night.
