Dry Firing Prior to Shooting comps

[rayhampton]

Can someone on here enlighten me please?
At all HFT comps that I have attended, peolpe with regged pcp's seem to want to/need to dry fire their rifles prior to shooting the first target on the course, is this necessary/important or just habit.
After asking some, I have had answers ranging from 'I just do it' and 'It needs doing' through to 'It settles the reg'.
I would have thought that if the rifle has been used on the plinking range prior to the comp, this would 'settle the reg'.

Just curious
Thanks in advance for any answers.

I do it

Mostly because i've just topped up with air prior to starting the course,
and yes i have a regged gun

but if i'd just come from the range with plenty in the tank i probably would'nt'
it's that long since i shot i can't remember

if the reg is "creeping" this will help to eliminate velocity variations.

I don't shoot comps but I dry fire all my PCP's a few times after filling.

I do it after a fill-up as i find the first five shots erratic, then true consistant shots follow. It works for me

If you dry fire surely you are not effecting the gun's performance in any way? In pistol shooting dry firing is just a way of honing your trigger technique without firing the gun,never seen anyone do this in HFT

It doesn't hurt a PCP to be dry fired, probably 99 times out of 100 it isn't necessary, but since it doesn't harm anything, it's sensible to just check everything's working before starting a comp. If it helps once out of a 100 times, it's worth doing isn't it?

I normally fire a shot into the ground when I start a comp - just to make sure everything's working ok.

i dry fire after filling as first few shots seem to have bigger variance over the chrono and my gun is regged

Not saying but it does make a difference

i felt this was a general rule of life hav a quick dry fire before the main event...avoid a premature shot etc
