HMR Grouping advice

[auto culto]

had a few probs with the grouping yesterday with my new CZ Varmint 16" so popped out today with a different batch of the rems 17 as advised and the difference is astounding. i was only getting 1 1/2 inch groups at 35 yards before and now is key holeing at 35. below is a pic at 125 yards with a good right to left cross wind shot prone from a 13inch bipod. Are these groups acceptable for a HMR or poor ? Having never had a hmr before i,m a little unsure. ( I normally get cloverleafs with my .223 at a similar distance).

Hi Bud have a look here.

Did a little bit of fiddling with my varmint cz

Forget about trying to set in a hmr in any kind of wind - it will drive you nuts.

 

From what I have seen a good hmr will group 0.5" at 100 yards on a good day, and 0.75" on an average day (with little wind).

 

OK, you may get the odd exceptional group better than this, but ON AVERAGE I think that the above will be about right.

 

This will enable you to head shot rabbits at 100 yards, and body shots at rabbits/crows etc well, well beyond this.

 

I too have a 0.223 and it will normally cloverleaf at 100 yards, but the hmr is so affected by wind that it can take a lot of experience to get to grips with the little beast.

All HMR Ammo according to Rimfire Central is only guaranteed to group 1" @ 100 yds .The difference between running fowled or clean can make a huge difference also as can time taken between each shot .

I zero my HMR in an old railway engineer tunnel, its where our club is based, therefore perfect shooting conditions - no wind, benchrested etc... and with a little time, practice and confidence I can cloverleaf 5 shots @ 100yds.... to try and zero during cross winds will have you chasing your mistakes all day. The HMR rounds are greatly affected by x-winds after about 60-70 yds and as for the zero at 35yds thing goes - I can't get that to work... zeroed at 35yds yds pretty much through the same hole... 125yds like a scatter gun Zeroed @ 100yds and 1/8" high @ 25yds - 1/2" high @ 50yds - 6 3/4" low at 200yds and that on my Hawke Varmint scope is 1 mildot holdover, and pretty much dead on from 20yds out to 130yds

Give it time to bed in as well - at least 500 rounds and it'll start shooting better groups, but as others have said you've got no chance in the wind.

try as many different makes of ammo as you can, you may find that it doesnt like the ones your using,

seem to be behaving itself atm but still goes daft with the other rounds so i,ll just use them up then buy some more

set aside half a dozen of each of the two remmy batches. put them in their own plastic baggies and label them 'good batch' and 'poor batch'. In a few hundred rounds, go back and compare them. I'd be willing to bet that you're just shooting the newness out of your gun. Yes, it can happen that one batch or another won't fly well. More often it is either a new gun that needs a little extra breaking in or a dirty gun that doesn't shoot well dirty. Save 6 of each so that later you can do some clean and dirty barrel testing once you've put a few hundred rounds down it and you know it is broken in. Some guns take less, some guns take more. 300-400 rounds should get you there though.

never found too much problems with wind if ranges kept to 100yds ish, gets blown about like any rimfire. somethings up if its inch and a half at 35yds is the barrel free floating? my quad shoots half inch most of the time, one of the lads got a brand new quad the last day and it also shot half inch at 100yds with less than 30 rounds thru it
