How far off is your 1st shot from a cold barrel?

How far off is your 1st shot from a cold barrel?

Say you go out and get a perfect 3 shot group from a slightly warm but definitely not hot barrel.  How far off from that would you expect your first shot to be from a completely cold barrel?

Every rifle is different but so far I'm not seeing enough difference to worry about. I do see a difference if I de-copper and de-carbon the barrel. Weatherby's seem to like a little fouling.

Cold and clean is usually not as close to the aim point as cold and fouled. Iíll define fouled as the scopeís zero was confirmed by two or three shots where they need to be and I leave the barrel ďas isĒ when I go hunting after that. If I know there is going to be drizzle or snow when Iím hunting Iíll dry punch the barrel and still be confident the first aimed shot will be where I want it, cold barrel and all.

Every man needs to know his limits.

Eford is right on the money.  What I do if it's going to rain or snow is put a piece of black electrical tape over the muzzle to keep the rain and snow out.  It doesn't have any affect on the accuracy or point of impact.
Nothing is better than a Weatherby, big bore magnum, or a Colt.

Thanks.  I'm thinking primarily cold and fouled.  No cleaning between range and hunting.  I've always been very close in the past, at least the animals haven't noticed a difference  ;D,  just wondering what other's experiences are and how far a cold barrel shot can stray from a warm barrel group.

Once I check zero,I don't clean until after season is over.
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

I try to avoid temptation unless I can't resist it.

Everyone has a photographic memory.Some just don't have film.

I noticed about 2Ē right at 100 yards with my Vanguard .375H&H. I will hunt with a fouled bore and as someone else said, put tape over the muzzle if I expect rain or snow.
