17hmr distance

[Highlander]

Stalking bunnies into rimfire range whilst using a centrefire is 'simply not cricket Old Boy!'

 

Where the hell did that come from??? I thought this post was about .17HMRs NOT centrefires! Another case of dyslexia

If you all read the starter thread he just wants to know how far a .17HMR will travel not how far will it kill.... :good:

H in my first post on the subject I said 'Dangerous within 1 3/4 or 2 miles' and it would be interesting to know if it does what it says on the tin...DANGEROUS!

[hawkeye]

Yes i read that but others were talking about killing range.

What angle would you have to shoot in the air to get that distance.

It says roughly the same thing on .22 rimfire about distance but last summer scaffy and myself were shooting on a farm, and one field is well over 100 acres it was a dry as dust and there were ferals on the field i was shooting to scare them and could see the bullet drop well short.

So kept aiming higher and higher till i was shooting at the top of the hills in the distance approx 35 deg and was still dropping miles short so how the hell do you get them to travel the distance stated on the boxes... :good:

If you apply this simple calculation you should find what you are looking for;

 

Reference datam;

 

.17 HMR Travel maximum distance outreach, ballisticus maximus correction factor 5.2% ABV after 7pm (in the case of Rabbits)

 

Therefore Cuniculus or Lepus can both safely be shot at a maximum range as follows

 

Taking the Ballistic coefficient of 30 grains of wheat on a moderate windy day it should take around 3rhs to dry a pair of coveralls if the wind chill is above 30 deg C with a 60 deg dew point and a velocity of .810 parts per million, the drag queen (Mungler) co efficient (drag and twisted effect) for the most part can be ignored as its always best to ignore the Mungler in the case of exposure to anything above 4% ABV after 7pm as in the case above. When tested with Remington standard rounds the rectinal hem aroids vortex must be taken into account if a Curry was on the menu at the dog and duck when said exposure occurred prior to the round leaving the chamber.

 

Hopefully that clears that up

well said...Like a lot of the posts on here that's (*****x) I mean 'as clear as mud'

As a matter of interest, does it really matter?

[bignoel]

well if you dont know then ask so it doe's matter

hear hear i hate people that dont want to learn at the risk of sounding like a newbie when asking a question!! its best to ask

 

 

soo if i point my 17hmr in the air ( WHICH YOU SHOLD NEVER DO) at 45% how far will it go

I think the bullets say dangerous to 1 3/4 miles, this will be absolute worst case with a howling wind in the direction and at the worst angle, and still will have value added to it, to cover their backs. But at the same time, it doesn't matter whether it is one mile or two. You should never need to know the answer to that. You can shoot vermin to about 150 with it, if there is a safe backstop, if there isn't you don't take the shot. Simple really.

highseas,

 

If you go to the link I posted above, it tells ou exactly what the absolute maximum rage would be and the angle at which you need to aim the gun to get it. 45 degrees is not the right angle because wind resistance is more powerful than gravity for most of the bullet's flight. For the case of the 17 gr coming out of my gun at 2600 fps, a 27.5 degree angle gives just under 2000 yards. That's a mile and a sixth or so. That is the maximum range you'll get out of it. The important thing to note is the angle that will do it. That isn't a very high angle. If you are shooting up a hill and don't have a good backstop, you could easily be shooting up at a 30 degree angle. If you don't hit dirt, that bullet is going a long way.

 

Thanks
