Thermal zeroing

When I zero I normally have a cardboard box in the back of the vehicle.... I then just put 1" or 2" square of sticky silver duct foil, thats available on rolls in the centre, I leave these in the vehicle... I then put the box at 30-40 yds, take a shot, use the one shot zero function then move to the target centre, take another shot to verify, when it's somewhere close I then move it out to 100 yds for my centrefires and repeat to verify.

When doing this, place a small 2" object under the front of the box to tilt it up slighty towards the sky, the tin foil will show a lot more vividly this way...

Also if checking zero at further ranges just used heat pads you can buy a pair from the likes of home bargains, B&M, etc for a ÂŁ1, the heel versions have a sticky backing, so you can put them on whatever...these emit a lot of heat if you cannot see the heat signature clearly with other methods...

If I'm out with the airgun or rimfire, I basically use the box and tin foil initially then after that, if I want to check zero when out, just shoot at a piece of wood, fenceline, tree stump, etc then aim at the impact point again, then use your freeze screen/ one shot zero to move to correct POI...... this method is very very quick and you can check/verify in less than a minute.....
 
I used the thermal feet warmers, the advantage is they come with a sticky side for you to stick them on your socks they go straight on a target holder or cardboard box set up. Used them today out to 100 yds brilliant
 
I use a 1 inch piece of foil tape on a black background, slightly tilted back.. Stands out like a sore thumb. This is at 100yds, I then put out some steel plates at around 250yds, heat them up with a blow torch, they stay clear for a least 30 min, job done
 
I use a 1”washer heated up at 100 yards as I find a 4” target is to big and you might not be aiming at exactly the same point every time and it’s harder to zero so it’s spot on,w
 
The foil tape from screwfix on a black back ground seams to work well I have sprayed a steel target with galvanising spray also from screwfix works in some conditions with a degree of success hope thats helpful
 
I tried all sorts of things like foil and hand warmers ect but the thing I have found works the best is I get a red bull can and fill it with water and then freeze it then stick it down range on its side so your shooting at it end on.
Works brilliantly for me every time.

Doesn’t it explode when you hit it?
