This.
Your 100 yard zero is your zero. It should basically never change. I'm pretty sure the environmentals would have to be staggeringly different to produce a "click" worth of POI change at 100 yards. For instance I tried it out with my hunting rifle's ballistics (assuming a 50 yard zero just to see if your temp difference would change my 100 yard drop), and it didn't change the 100 yard drop at all.
First of thank you very much. I’ve hunted for many years but never really took too much noticed to a lot of minor details.
Given this information I'd say it's you managing the rifle way different in the prone versus the bench you zeroed on.
You’re probably right boot ass gunny
Thank you , I’ll try the bench again just to confirm and zero for prone seeing that I will never hunt using a bench.
This is semi-related but if you don't already have a tripod you can shoot off of, consider getting one. Having a good tripod has changed everything about my western spot and stalk hunting. A few weeks ago both my father and I used my tripod to shoot antelope at 360 yards from a fully standing position since we couldn't get lower (two different locations/days, coincidence that it was same distance for both). Last year I killed a coues deer at 380 across a canyon using my tripod from the sitting position. It's a complete game changer.
Mine's kind of overkill/heavy/expensive. I use a TFCT-34L w/ Anvil ball head with a PT-Scout pan head that I clip into the Anvil for glassing. I can unclip the PT-Scout with my binos on it and have my rifle locked into the Anvil in about 5 seconds. But you could theoretically put a tripod together starting at $600 that would be lighter and stable enough for hunting situations.
I’m going after work to shoot on the bench , hopefully the club out here is done shooting . I feel as though I was aligning everything correctly and the only thing that shifted was that I shot two inches lower . Left and right didn’t move at all
Excuse me if this is an elementary question but I don't know your user level or experience.
Your NF may not have actual yardage numbers on the side knob and the range is likely closer to 35yds+/- to infinity.
I figured out the issues . Wasn’t anything crazy. Every time I would go shooting and had the rifle sighted in here in AZ . It was plus 105 degrees. So the barrel was always “hot” . Today when I went the barrel was finally cold so my shots were lower. Once I got the barrel to warm up it started shooting a higher. Not sure if that makes sense
