cold bore is killing me

Hey all..im pulling my whiskers out here...here is the set-up

30-06 browning a-bolt, stainless factory barrel, walnut stock...havent cleaned the rifle in a while, perhaps 40 rounds through it since last cleaning...i went out today, and the first shot was around 4.5 inches high at 100 yards...i have it sighted in at 2.5 inches high at 100 yards...after the first shot, the rest settled down to where it was zeroed at...now, i know this isnt a precision rig, and 1 moa out of this gun is about as good as i can get, even with handloads..but this 2 inches high thing is killing me...anybody have any clues why and what i can do about it?...could it be moisture in the barrel slicking things up making that first shot faster?

I zero my rifle for the first shot thats how you have to do it. You can not take a few shots at the animal so you can warm up your barrel.

Re: cold bore is killing me

Agreed. The cold bore shot is the important one, but that is, in a small part, why so many of us here have invested so much time, money, blood, sweat, etc., into our rifles. We seak out any way to improve them. I would say that most end up with a synth. stock, floated barrel, bedded action, and trigger work.

Wood stocks with an unfloated barrel can be very finnicky with temperature and humidity changes, even with barrel temp. changes.

I agree about a lot of wood stocks being more touchy, most wood stocked rifles I have had that were not properly bedded would do this. I think Browning rifles are supposed to be free floating barrels but I would look carefully around your barrel to check for obvious contact between the stock and barrel.

Re: cold bore is killing me

Have you put your rifle in a lead sled or other shooting aid for a cold bore shot. Most of the time, the reason the first shot seems to seperate it's self from your POI is human error. No matter how many times you've fired that rifle the first shot of the day will be met with a tence anticipation more than likely causing an unnoticed flinch or extra pressure from your firing hand. Try dryfiring 5 or 10 times before you put your 1st round down range next trip, it might help settle things down.

+1 a lot of the time it is cold shooter not cold gun.
Try taking another gun to the range and shooting before you set up with the 06. Shooting a 22 off the bat is great practice.

Re: cold bore is killing me

im pretty sure is not me..that has to be the most common response right?..lol...the barrel is free floated, but i would imagine it needs a bed job...in all seriousness though, this isnt my first rodeo, ive been shooting for 20+ years now, and the 06 isnt exactly a light wieght, but the recoil is still far from unpleasant...here in kentucky, the longest shot i have ever had was 325 yards, so i know 2 inches isnt exactly crucial in this particular application, but the whole "good enough for hunting" mentality rubs my butt with a corncob...the thing that really got me wondering was tat usually code bore shots tend to be low, with subsequent shots stringing upward as the barrel heats...that struck me as odd...once the first shot is out, it groups reasonably well, but that first one is always high...should i run a dry patch through it before the first shot...would that change anything?
