Savage 12fv accuracy problem.

[Vic1]

Hi,
I have a Savage 12fv in .223 and can't find the problem.
I'm still in process of developing the load and getting better groups every time, bat every time I change the weight of the bullet my point of impact changes in horizontal plane. When I changed from 52 to 68 gr, point of impact changes 14" @200yards.
Any ideas???????
Thanks,
Vic

i talk to a guy from ks arms and he thinks the rate of twist could be wrong his opinion just throwin it out ther

to put this simply yes you will get a Point Of Impact change every time you change bullet wieghts or the powder charge . The premise that the rifles barrel twist is the factor is horse puckey. I have a Savage 12FV in 223 it shoots both 55gr and 77gr bullets quite well and yes there is a POI change

If you are shooting outdoors, which I assume you are at 200yards, the wind drift on different weight bullets will be different. Depends on the BC of the bullet as well.

As long as the group is tight, never mind the POI...that's what the knobs on the scope are for

"...changed from 52 to 68 gr..." That's normal. Every rifle will shoot different ammo to a different POI. Mind you, 14" is a bit much. However, don't worry about the POI until you have a load your rifle shoots well. Like Obtunded says that's what the knobs on the scope are for. Work up the load, shooting for group only, then adjust the sights.
Your rifling is 1 in 9. Your rifle will likely prefer heavier bullets.

Thank you all for reply, this is my first rifle in smole caliber and I would never guess that POI would change that much, specially in horizontal plane. I was ready to take it for warranty repere.
Groups are good (.75" @ 200yards, open range with 68gr Hornady hpbtm, without find tuning).

I have the same rifle. When I went from trying out white box 45 grain bullets to my long range load of 75 grain Amax I had a 5" high and 5" left adjustment at 100 yard, pretty drastic!

POI will definitely change with different loads. Given such a difference in bullet weights, a 14" change at 200 is not surprising. Sounds like the gun shoots great though, so just pick your favourite load and site 'er in!
