i think 4fbs is the mini , you need to kill a rabbit stone dead , so at 40 well in , i say

you can work it out on chair gun ,

atb mate

didnt realise that you could hit any thing at 40 yard

I seem to remember that I read it was 6-7fps at 45mt but probably wrong, I usually am

Play around with the above. Scroll down to ballistic calc.

Its feet per second at 40 mtrs i would like to know phil, cheers pal

Using a 8.44gr pellet in .177 to achieve 4ft/lbs at 40m you would need 600fps (6.75ft/lbs) at the muzzle which would equate to 464fps (4.04ft/lbs) at 40m.

 

I have heard 3ft/lbs to kill a rabbit, so 400fps in 8.44gr at 40m. So a muzzle energy of 5.07ft/lbs.

 

Thats my calcs using chairgun.

chairgun is a program for the computer made buy hawke for working out your mildots

on the far left of the screen is a table that tells you the energy retained at variose distances!

play about till you hit 3lb then the fps will be next to it

My .177 R10 using 10.34gr exact heavys if using the 4ft/lbs to kill would be ok at 115 yards.

Nice one gents, thanks for that

The gun is hw100, pellets 10.34 jsb heavies, 700fps so 11.2 ftlb

I just wanted to make sure it was good enough to do rabbits at a 40 mtr distance

before i put the nv on it and take it out.

Il be shooting no more than thst distance so it sll sounds good

[si brown 8,486]

At 45yrd you'll be hitting it at 7.90 ftlbf!!

and doing 587.7 fps

Plenty enough bn

My R10 doing 710fps at the muzzle had the 10.34gr exact heavy's showing a bc of 0.0271. I reckon 575fps 7.6ft/lbs at 43 yards 40m approx.

 

Enough to go in and out the other side....lol watch your back stops.

Cheers si, gary atb

That's the same combo that I use BN

 

...... you'll easily take rabbits at 40 mtrs. If things are going well, you can add another 10 mtrs and still have clean kills
