cold barrel shot vs group

what can i do to get my cold barrel shot to group with the rest of my shots. My cold barrel shot is 4 inches right of the point of aim at 200 yds. The next 4 rounds are a nice little group right at point of aim. I am shooting a savage 110 fcp lapua, berger 300gr hybrids, lapua brass and 85 grains of h1000. i really use this rifle for hunting so the first shot is important.

Re: cold barrel shot vs group

If this gun is used for hunting and you really have that big of a problem with your 1st clean, cold barrel shot, then I would do a test to see how your first clean cold barrel shot groups. I would shoot the first shot and clean the gun. Let the gun cool down all the way and then shoot again. Do this about 5 times to see what kind of group you get. If it groups good and consistent over time, I would just sight your gun in for that first clean, cold barrel shot when you hunt.

Re: cold barrel shot vs group

Is it just cold bore or is it a cold and clean bore? A 4in difference is unacceptable at long range let a lone at 200 yards!!

cold bore, and the gun shoots 4 inches right every time on a cold bore. It shoots just over a half inch at 200 yds for the next 4 shots. it is very consistent just not perfect.

Re: cold barrel shot vs group

If the first shot from a clean barrel is off, then you just shoot a round then go hunting. If you know where the first shot consistently groups from subsequent shots, then you hold over that amount when you shoot the first shot. Either method will work.

Most people use powder that is temperature sensitive, and at long range the cold weather vs. warm weather difference will swamp out any difference between a first and subsequent shot. IMR 3031, which is a common .30-30 Winchester powder, is extremely sensitive to temperature changes.

You don't hunt at long range with a clean barrel anyway, if you have any sense at all. You foul your bore to a consistent result and then go hunting. People who are successful long range hunters have been doing this for a lot longer than I have been around.

Yeah..that is pretty crazy. If you sighted it in for the first round, it would suck if you had to do a follow up shot.

NAILED IT!

Now to the OP, your way of thinking is messed up! Its a hunting rifle, you said it yourself, therefore fallow the above advice wait 10 min between shots and that's your group, that's your zero.
