Zeroing

When zeroing a 223 does it make a different if the barrel is cold or hot

[Bootsha 1,306]

if you were in competition mate, you'd be allowed 3 shots to foul / warm your barrell ( i think), when your in the field your taking the first shot, with a cold barrell, so i'd be more inclined to zero from cold, because the first round you send at the target from a cold barrell, is the first round you'll be sending at your selected prey species. Its the first one that counts

good advice from above, always try to achieve a cold bore zero when hunting, As you want the first round to be on target,

Ok thanks very much lads will know that for the future

You should wait a minute or two between shots. This will give your barrel time

To cool down. Giving you better grouping.

i checked one day how long it took my cz .17hmr to cool after each shot wit a internal food thermometer,

 

it averaged 50seconds to cool but this was in the summer.

Iv redone my zeroing today and let the barrel cool down and it was much better grouping thanks for all your help

HMR will make very little difference, you will have to fire a LOT of rounds down even a light HMR barrel, in very quick succession to warm it up to any appreciable extent.

 

10 shots quickly down a .223 and you will have a very hot barrel!

 

Just the same, Zero COLD!
