bullet drop question

[Kinjo]

I was on the 300 yrd range a couple of weeks ago with -3 to -4 C , original zeroed @ 100 yds about 3 to 5 C. Shooting a 178gr hornady matched 308 bullet chambered in my Remington 700 aac. I sent the first round, dead centre, second round 6 - 7 inches low. Checked my ballistics and I had adjusted correctly.
So my question is the barrel or is it the scope?

Thanks,
John

Or the shooter?

Re: bullet drop question

it's the cold bore shift and environmental difference

Where did the rest of em go? Or did you stop at two? That will tell the rest of the story.

Re: bullet drop question

I don't think I was doing anything different thats why I eliminated myself out of the equation. Plus that much? I don't shoot that bad, I know that much.

I continued to send a few more, as I clicked on more elevation they continued to walk up the target. It's just that everything was fine right up till that day. I've been shooting regularly then I go out and this happens.
I figured maybe the temperature shift had a part to play in this.

I would see if it repeats itself before trying to pinpoint one reason for the shift. One occurance isn't something I would stress over right away. If the issue persists, start eliminating variables one at a time until you figure it out.
