17hmr

[adi786]

hi guys,

just after some input, i haven't used much 17hmr, but couple weeks back i zeroed it at around 75 yards, last time i went out and it was quite windy, put a target at 100 yards and i had no clue where the bullet was going, put a wider board and found out they are going around 6-8 inches right of the bulls eye, i still believe that it should;nt be a wind effecting that much at 100 yards, must be something happen to my zero. What you guys think how much a wind would effect 17hmr at 100 range say you shooting straight down the line and wind is pretty strong from left to right?

 

[Underdog]

It will be the wind.

My friend has a 17rem years ago and the wind would reap havoc on the bullet incidentally heavier and faster than yours.

The wind takes my22 wmr way off too!

[Harry Callahan]

The HMR is quite susceptible to wind issues.

 

If your shooting across the wind, and its 'pretty strong' as you say, then yeah - 6-8inches drift is no surprise atall. Even a stiff breeze can alter the flight by a couple inches.

 

Wait for a settled day and try a target again.

Yes wind is an issue certainly but I find the biggest problem with my 17 is cleanliness, if I don't run the boresnake through it regularly it will be all over the place.

So keep it clean and that includes taking the moderator apart and giving it a good clean. It is in my experience the most fussy calibre I have.

Iv never cleaned my HMR and it fires true. I clean my mod. every 500 or so rounds and never notice any difference. Iv had my rifle, from new, coming up for 10 years.

As a guide line, at 100 yard range I assume 3" drift with a 10 mph cross wind.(Hard to say what 'pretty strong is'.)

A weather app will give you good idea of local wind speeds.

[adi786]

well say 15 mph, didn't expect tha 17 hmr would drift that much, i was thinking totally the other way, i.e. they are pretty quick and probably wind wont effect them that much as it'll take them hardly any time to reach the target at 100 yards.. I have cleaned it once so far since new, as above someone said after 500 or so shots, i read same somewhere else that most normally clean after around 500, and i've shot maybe 50 / 100 max after first clean.

 

Also do you guys prefer 20gr over 17gr?

[Rimfireboy]

I find that the 17 grain ballistic tip bullets seem to kill better on small vermin, but the 20 grain bullets have the edge on accuracy in my rifle.

[Underdog]

Don't think of it as wind blowing on the bullet but more like the whole environment the bullet is passing through is moving. Does that make sense?

never took it this way ... used to be like wind blowing and forcing pushing bullet away.. thx

Your practical experience is far more valid than any table which at best can only be a guide. It largely depends on the conditions that prevailed when you actually did the zero. Simply as a guide, if your zero was set in a calm condition, then at 100 yards and your 15mph cross wind, a tad under a 5" drift could be expected.

Yep, I'd go with that.

 

20gr hollow point CCI's are a joy to fire and accuracy is perfection. But on crows the 17gr poly tips (Hornady) have so much more capability.

[mick miller]

To be honest I'm surprised you're getting this amount of drift. Most people know that the little hmr pill 'isn't affected by wind' and is 'deadly accurate out to 170 yards' where it 'stops foxes dead in their tracks'?

It's an amazing round really, when you consider that centrefire rifles rely on accurately measured loads tuned to barrel harmonics, perfectly resized cases, consistent bullet seating depths matched to chamber size to achieve the same level of accuracy at 100 yards and greater; Hornady really did break the mold when they produced the Hmr.

After all, here's a mass manufactured cartridge, with inconsistent seating depths, split case necks, inconsistent priming compound amounts, variable powder quantity (which in any other comparably sized case results in massive variations in speed and pressure) manufactured to fit any 17hmr rifle, regardless of make, which manages to achieve the same levels of accuracy as those bench rest type dudes do.

I suggest, as prescribed to me, you just need to 'shoot more often' as you haven't spent enough time with this miracle cartridge.

(for what is really worth, I've experienced the same as you. Still days it's fantastic, but not consistent. Add a little breeze into the mix and those groups open up considerably).

 

Have you tried Hornady, Remington, CCI, red, blue, purple, gold pink tips? I find these really good (until I buy another batch that is).

Lol.

I was using mine out to 190 yards the other day on 3" gongs and once I'd corrected the wind it was hitting the same spot each time . 2-3 " at 100 yards on paper , 5-6" at 200 yards . In the same wind my 223 was straight at 100 but 2" at 200 and 8" at 350 yards.

[mick miller]

Was that with pink tips or blue?

[Dougy]

Has anyone tried colouring the tips black or yellow.

[Harry Callahan]

Has anyone tried colouring the tips black or yellow.

Am I missing something here? Why would you want to colour the tips?

[welshwarrior]

Yes black ones shot left and yellow ones drop short. May just be my pens, but stripy ones shot best.

Try Tipex, much better

Wind has a big effect, my mate had wind today and he stunk , ruined my day I can tell ya.

so far i have only tried winchester/hornady 17gr rounds... the others are mostly not available around me... agree iu be going out soon and will be spending probably all day just doing targets down field.

It is worth while having a read on here about miss fires and when the bullet has got stuck up the barrel and the potential danger of this, especially for when doing a lot of rounds in one go.

 

I've had lots of miss fires, but haven't had the head only go half up the barrel, but I keep a rod in the car now in case.

 

If I get a miss-fire, I ensure I check round is fully intact on ejection before chambering the next one (i.e if you get a miss fire whilst looking at a bunny, don't just re-chamber a new round and fire whilst looking through scope) and if I hear a unusual sound compared to normal of the shot going off, I take bolt out and check barrel clear.

At night I keep a small LED keyring with me which gives off a fairly low level light, and if In doubt I take bolt out and point business end of barrel at light and look through from the back - that way I don't have to go back to the car or use a huge beam of light to check barrel clear.

 

This may seem like a hassle, but seeing the damage done by shooting again when barrel obstructed will ensure I keep this up.

 

(For info, this rarely has happened, reckon I've checked barrel is clear after a funny sounding round maybe 3 or 4 times in shooting upwards of 1500 rounds from my HMR).
