SHOT YESTERDAY AFTERNOON AT 98 DEG. THIS MORNING AT 64 DEG. I WILL DO 2 PICTURES AT A TIME. 15YDS. I have a Diana Stealth. I’m using H&N hunter trophy target 14.66 gn.
shooting at different tempetures
- Thread starter DAVEFISHING
- Start date
Hot air is less dense than cold air. Spring guns compress Ambient air to power the shot. 35-40 degree delta air temp can cause significant delta air density.
Wish I could help.

My HW97 behaves pretty similar, but maybe not as extreme as you are seeing. At this winters field target matches I would get a 3moa shift from 40f to 70f through a match. It is just something you have to learn about your rifle. I was able to duplicate it at the house on cool days by going outside and shooting as the gun cooled down the poi would change.
They did a short test of some rifles on American Airgunner last season at room temp then out of a deep freezer. Counter to what the advertisers are saying, the Nitro piston rifle they had on hand had way more of a velocity shift than the spring gun.
