I've had mine about a year, and initially thought it was brilliant, until I started reading about 1/2" groups at 100yds which mine has definitely never been able to do! (I can manage 1" groups at 100yds with 5 shots of a 22lr and 3 shots of a .243 so I'm pretty sure it's not me).
I've tried everything - different mods, different ammo, different scopes, benchrests, crown checking, cleaaning, not-cleaning, etc - the only things I can think it might be is that I live on the south coast and there is always a little wind here, and I have a 16" barrel which depending on who you talk to means there is only one turn of the rifleing + less FPS and this can mean it's unstable past 80yds?!!!?!
I came across this american post, and further down on the replies FranknHollow goes into the lack of consistency of weight of the HMR rounds, and the fact that it is so light the slightest wind will throw it all over the place: UtahConcealedCarry.Com View topic - 17HMR accuracy expectation - Need opinions
Has anyone else had issues at 100yds when punching paper? - yes I can cleanly kill at this distance, but this winter I've inexplicably totally missed a few really easy shots at 100 and can only put it down to the increased wind. I've lost confidence in my 17HMR and am just sticking with my .22 and .243 until I work out what the issue is.
Does anyone have experience of this and if so can you genuinely do single hole groups at 100yds? - if so what are the specifics of your rifle?
I'm either going to up this to a 20" barrel, or just say b*llox to it and get a .223 or a 222! - I'm using it for bunny and the odd close fox, but may as well use my .22 for bunny and chop my .17 in for a 223/222 for fox and the odd bunny!
