nichard 4 Posted March 28, 2012 Report Share Posted March 28, 2012 If a .22 @ 11.5ft lbs can accuratly kill a rabbit at 35 yrds at what range could a .22 @28ft lbs do it? Quote Link to post
ryan666 64 Posted March 28, 2012 Report Share Posted March 28, 2012 at 11.5ftlbs it can kill alot further out than 35 yards...just down to the shooter behind it 1 Quote Link to post
AngryHan 4 Posted March 28, 2012 Report Share Posted March 28, 2012 Not sure what you mean by "accurately kill" - accuracy is based on pellet, rifle quality and operator alone. The power has little to do with accuracy. Unless you mean 'cleanly kill'. I believe (please correct me if I'm wrong) that 5ftlb at impact is enough to kill a rabbit if you shoot it in the head. According to Chairgun, with a 28ftlb at muzzle, you've got 110 yards before the energy drops to 5ftlb. 1 Quote Link to post

AngryHan 4 Posted March 28, 2012 Report Share Posted March 28, 2012 (edited) Could well be 3ftlb, gives me the incentive to practice to push my sub-12ftlber even further! Having done some further research (ie. searching around various airgun boards), 3-4ftlb seems to be the number people are going by. Edited March 28, 2012 by AngryHan Quote Link to post
ryan666 64 Posted March 28, 2012 Report Share Posted March 28, 2012 yer and at 3ftlbs and a head shot on a rabbit it wont even penetrate but mr.bunny will roll over and die Quote Link to post
Phantom 631 Posted March 28, 2012 Report Share Posted March 28, 2012 It can actually take a lot less than that to kill a rabbit, if if you can deliver point four of a ft/lb of energy to the correct part of the nervous system, according to the scientists (the Cerebellum or 'little brain' the bit that keeps the heart/lungs etc functioning) the bunny will roll over and croak immediately. Of course that little energy at the front or top of the head will do little more than give bug's a bump on the bonce and a bit of a headache! Tony Quote Link to post

Not your rifle buddy, you as mentioned elsewhere, the weak link (apart from early B2's and the like) is always the shooter There are also many other variables to the equation! Air resistance (atmospheric pressure), humidity, wind, the surface of the pellet, daytime/nighttime temperatures etc.... Thats why you need to learn your ability to shoot under differing conditions.

pianoman 3,584 Posted March 28, 2012 Report Share Posted March 28, 2012 (edited) The above answers are all of merit. Can you shoot to the limit of your rifle? But really, if you need a rifle with power to kill at such long ranges, you should be looking at a Rimfire/Centrefire job on your FAC.. I can confidently hit a rabbit straight through it's head at 25 to 60+metre ranges, depending on weather/wind conditions, with an 11.5ft/lb .22 spring rifle. That's far enough variance distance away for me! The target brain area starts to look awfully small once you get to 35-40+ metres distant. Simon Edited March 28, 2012 by pianoman 2 Quote Link to post
Extremetaz 15 Posted March 28, 2012 Report Share Posted March 28, 2012 Even assuming the availabilty of kit and ammo group under an inch at 100m (110yard as suggested by Angryhan) from a 12ft.lb rifle, and the triggerman who can do the kit justice, the 28ft.lb rifle isn't going to make a huge difference. It might give you an extra 10-15 meters, but the bottom line is that air rifle pellets are far too ballistically inefficient to be any more stable at higher velocities. ie: just because you send it out there faster, doesn't mean it's gonna go where you expect it too - in fact, it's more likely the opposite is true. If you could get a heavier, jacketed, boat tailed projectile and find the means to chamber it consistently, and get a consistent barrel seal with it, then maybe you could expect to see decent range benefits. However, in the absence of this, I think the only thing that the extra power will really allow you to do, is to send a heavier projectile downrange with the same initial velocity. This won't give you a whole lot more wrt to range, but it'll give you a more "persuasive" impact when it gets there. What range benefits you do get then, will be down to better velocity retention in the heavier projectile - but I reckon it's still gonna loose its spin and go unstable shortly beyond 100m no matter what you do.

Skot Ruthless Teale 1,701 Posted March 28, 2012 Report Share Posted March 28, 2012 so if a .177 is doing 11.7 ftlb at muzzle, what is the distance that the pellet will travel until it will be impacting at 4 ftlb ?? (say for examle.. with air arms diabolo field pellets . 8.4 grain) Quote Link to post
AngryHan 4 Posted March 28, 2012 Report Share Posted March 28, 2012 a 8.4 grain AA field pellet fired at 11.7ftlb will reach 4ftlb at 90 yards I advise downloading the excellent Hawke Chairgun program, probably the best tool out there for modelling pellet ballistics. 1 Quote Link to post
Skot Ruthless Teale 1,701 Posted March 28, 2012 Report Share Posted March 28, 2012 90 yards ey! cool. at the min im only shooting at about 40-50 yards with my .177 springer. might increase that range as i get better with practice. but now i know 90 yards is the 'kill' limit even if i get really good i wont shoot further than that. would be quite irresponsible. cheers pal 1 Quote Link to post
AngryHan 4 Posted March 28, 2012 Report Share Posted March 28, 2012 If you can reach out to that range accurately with a springer, then kudos to you! Quote Link to post
Skot Ruthless Teale 1,701 Posted March 28, 2012 Report Share Posted March 28, 2012 If you can reach out to that range accurately with a springer, then kudos to you! well aparently it would probably be 'easy' to most of these 'snipers' on here with there pree charged!! im quuite happy getting in closer to stuff and going for an easier shot. less risky and a lot more respect is given to the quarry. plus its fun and a challenge. better than setting up and waiting until something lands or pops its head up at long range then all you have to do is move your bipod slightly and squeese the trigger! thats just my view though. each to their own i say. i like to be active when im out hunting. sneeking around slowly and stalking is more my cup of tea than the sit and wait approach Quote Link to post
