Thread: Factory ammo fliers every 3 shots

Hey team.
Took my new rifle out for a spin today.
She's a winchester mod 70 243.
I intend to reload for it and have ordered some eldx 90g which should be here mid February.
I bought some hornandy whitetails 100g soft points just to run through it in the meantime as I can use the brass.
I put 20 rounds through the rifle today getting a feel for it and sighting in.
But I foubd that I could put 2 shots almost on top of each other and then the 3rd would always be a flier 3 or 4 inches higher.
Any idea what would cause this ? Or is it just me getting used to the rifle ?
Very happy with everything else it shoots nice trigger is good no creep and about 2.5lbs of pull. It feeds really well too.
It's not an issue for hunting too much as I have never needed 2 shots to kill anything but just curious as to what might be causing the fliers.
Took thd rifle home and gave it a really good clean just with patches and gun oil.
If nothing here sheds light I'll take it round to a mate and get him to put a few down range to see if it's just me.
Thanks
