New HMR accuracy.

[vole]

Just done a bit of a zero with 17gr V Max. Not getting such good results,probably down to me mainly but how many rounds down a new barrel before its settled in on average? Cheers!

It can take a few hundred rounds to run some new barrels in, it can vary from gun to gun and unfortunately there is nothing written in stone, only guidelines.

Different guns (Particularly .22LRs and HMRs) have likes and dislikes in ammo so you might well have to try a few differemt types before you find one that your rifle likes. I have a CZ452 Varmint (17 HMR) and it does not like Hornady at all and will only give me a 2 inch group (At best) at 100 yards yet will put shot on top of shot (Half inch groups are easy) with Remingtons at the same distance.

What rifle and set up do you have? Have you checked that the scope is properly mounted and that the scope mounting screws are tight so that there is no scope creep or movement?

While setting and checking the zeroing it might pay you to use a bean bag (Or even a firm cushion if shooting off the bonnet of a car or 4x4) to rest on or better still a bipod. (If you do not use one already)

Hope this helps mate!

Even rimfires take a few rounds to settle down (sometimes quite a few).......

 

Funny old world, when new, my 452 Silhouette HMR preferred Hornady 17g without doubt, tried CCI, Winchester, Federal, Remington...about everything I could lay my hands on.....some 3000-3500 rounds later I decided to use up all the part boxes I had lying about and there is next to nothing in it, even the 20g group well now!!!

 

The Hornady still just edge it though in my book...but remember, a lot of shooting is in the mind, if you feel confident you will probably shoot well, and if you don't......

The age old question of this little calibre, my CZ 17hmr 16in Varmint is rubbish with Remingtons, reasonable with Hornady and lazer(most of the time) with cci. Have a look around other threads on this site and you will find this subject comes up time and time again. Buy as many brands as you can afford/get hold of and test em at 100yd, clean barrel before testing each one and make sure its a still day with not a breeze.

I do use a bipod but will try a bean bag under the stock off the bench if I can. Your suggestion about the scope is a good one. I had to take the mounts on and off a few times,have heard that makes the screws come loose.

I have a Marlin 917,the base model and SAK moderator plus bipod. Scope is Nikko Stirling Gameking, 4-16 x 50 AO. Have used Hornady 20g and Remington 17gr so far. Sometimes I think I have it spot on nearly hitting a 1p size at 50 yards then get another loose group 2/3 inches off. All good learning experience though. Thanks for all help,good to see other threads on the same subject.
