harveykeitel22 Posted May 21, 2009 Report Share Posted May 21, 2009 Hey guys, im seriously thinking about getting a 17hmr, ive been told they r badly affected in the wind, can any of ya tell me how bad are they affected in the wind? Quote Link to comment Share on other sites More sharing options...
MC Posted May 21, 2009 Report Share Posted May 21, 2009 Depends how strong the wind is, You will miss more due to your shooting ability than you will because the wind pushed your little bullet away Quote Link to comment Share on other sites More sharing options...
harveykeitel22 Posted May 21, 2009 Author Report Share Posted May 21, 2009 well i take it you just aim differently, in the wind Quote Link to comment Share on other sites More sharing options...
wannabefisher Posted May 21, 2009 Report Share Posted May 21, 2009 a 17hmr will drift 5" over 125m in a 10mph cross wind. so lots compared to a CF, little compared to a 22rf Quote Link to comment Share on other sites More sharing options...
al4x Posted May 21, 2009 Report Share Posted May 21, 2009 or reduce your range. In reality it doesn't make that much difference if you restrict yourself to 80 yards or so in reasonable wind, however try 150 yard shots and yes it will move appreciably Quote Link to comment Share on other sites More sharing options...

I don't have a way of measuring the exact speed but when there is a "strong breeze" it can easily make you clean miss a rabbit completely if you don't change your aim. here are the raw ballistics for you too http://www.varmintal.com/17hmr.htm#Wind Quote Link to comment Share on other sites More sharing options...
Beardo Posted May 21, 2009 Report Share Posted May 21, 2009 i agree totally - i always head shot if possible to save meat damage, and a good stiff side wind will mean you miss completely at 100 yards if you don't compensate. how much just takes practise. i love the .17, the bunnies don't Quote Link to comment Share on other sites More sharing options...
CharlieT Posted May 21, 2009 Report Share Posted May 21, 2009 I have to disagree with you there - Ive been shooting an HMR for a couple of years and never once had to adjust my aim for wind The round travels at 2550 ft/sec wind of 10 mph has little or no impact in my opinion even at ranges in excess of 125m Les Chuck Hawkes states that in a 10mph wind, drift would be 3.3" at 100 yds and 8" at 150 yds. Not surprising for such a light round. Quote Link to comment Share on other sites More sharing options...
Billy. Posted May 21, 2009 Report Share Posted May 21, 2009 The round travels at 2550 ft/sec wind of 10 mph has little or no impact in my opinion even at ranges in excess of 125m You must be kidding. I leave the 17 at home on a windy day. Just because it goes fast doesn't mean it's unaffected. I zeroed mine at 32 yards on a windy day and the bullets were pulling to the left.

Does all your shooting take place in a near-vacuum? Wannabefisher, buy a Kestrel (or other) hand-held anemometer if you genuinely need to assess wind when shooting.

deadeye ive Posted May 21, 2009 Report Share Posted May 21, 2009 I have to disagree with you there - Ive been shooting an HMR for a couple of years and never once had to adjust my aim for wind The round travels at 2550 ft/sec wind of 10 mph has little or no impact in my opinion even at ranges in excess of 125m Les Well Lez i can clearly say that either you have never used a anemnometer(Wind measuring device) or have no idea what a 10MPH wind is like . My .223 pushing a 50grn pill @3500 fps drifted 1.75" over 100 m in a 15mph cross wind so i would say 5" seems reasonable for a 17grn over a similar distance in less wind . BTW are you aiming for head or body? Quote Link to comment Share on other sites More sharing options...
Billy. Posted May 21, 2009 Report Share Posted May 21, 2009 Are you converting one .17 HMR to permanent NV use? Yeah, I'm planning on splashing out on a proper bit of kit after i've saved for a bit...! I might stick it on my .22lr though, as it's so so so bloody quiet in comparison to my s/a.

dieseldogg Posted May 22, 2009 Report Share Posted May 22, 2009 Re wind deflection From my service rifle shooting days At 500m prone with SLR ( the section match as I recall) In a stiff cross wind at Magilligan, I was shocked at how far off into the wind I had to aim, I would almost say 1/2 way between the frames, from hazy recollection. I am sure someone can provide the ballistics, wind could reasonably have been 20/25 mph Quote Link to comment Share on other sites More sharing options...

BTW are you aiming for head or body? I cant say Ive notice any problems with wind- :blink: and I did say in my opinion guys- opinions are sometimes incorrect- I usualy go for head shots and dont miss many shooting off a bipod- my HMR is zeroed at 75 yards and I shoot anywhwere between 75 and 125 yards Maybe Ive never experienced wind that you guys have come across - but as I say I personally have never had to aim off for wind- I have 25,000 acres to shoot over most of it is in a valley south of the Quantock hills- not often windy and I cannot honestly say Ive ever thought to measure it But I will bow to your superior knowledge Not looking to start a war or anything atb Les Quote Link to comment Share on other sites More sharing options...
Baldrick Posted May 22, 2009 Report Share Posted May 22, 2009 Maybe my earlier post was a tad forceful, Les, but I'm genuinely surprised. Do you make a concerted effort to either shoot straight into the wind, or with your back square to it? In a valley, with katabatic wind, you'd normally expect greater wind speeds that the surrounding flatter areas. I'm shooting on flat land in East Anglia, and we've had a consistent 16-25mph wind for the last 8 days, gusting up to 37mph (I checked the logs from the weather station on top of our grainstore this morning). I've been doing a lot of shooting with my HMR over the last week, and as the wind picked up this morning, I was definitely having to compensate. Even with a wind-bucking 180gr round from the 7mm, I'd still allow for wind at over 100 yards if it was on my quarter. Quote Link to comment Share on other sites More sharing options...
tungsten Posted May 22, 2009 Report Share Posted May 22, 2009 Not got a 17 but thinking very hard about getting one! Looking at my ballistic calculator and plugging in Hornaday V max 17gr with a 10mph cross wind at 90 degrees it shows:- 20 yds 0.16" 30 yds 0.31" 40 yds 0.52" 50 yds 0.81" 70 yds 1.59" 90 yds 2.67" 110 yds 4.09" 120 yds 4.93" I was also talking to BASC on a different topic and got on to .17 calibre and he was also saying .17's are very wind prone, from tests they had carried out. all above not my opinions just info available in public domain.

Lez325 Posted May 22, 2009 Report Share Posted May 22, 2009 as said - I usually shoot from a biopod or my 4x4 I try to get face into the wind if there is any- stay up wind of bunny or fox as is normal Maybe Ive just been lucky where wind did not play a part - a tad forceful maybe - but we are all entitled to our opinion Baldrick and I value everyones opinion so long as its the same as mine LOL :blink: Les Quote Link to comment Share on other sites More sharing options...

If you paper punch then of course you will. Quote Link to comment Share on other sites More sharing options...

Im not disputing hard facts- just saying I have never experienced this problem where I shoot :and according to your chart above even being 4.93 out at 100 yards would still result in a dead bunny as they are a tad longer than 4.93" :blink: Ok I give up- maybe I'll sell the hmr and stick to shotguns lol Les Edited May 22, 2009 by Lez325 Quote Link to comment Share on other sites More sharing options...
