Thread: rifle change / load/ no bumps etc

So, about a 1month ago, I finished my load development for my 7mm saum.
I zeroed at 100, verified out to 550, then verified out to 760 on a 6inch gong. 2x.
Took it out the following week and shot 2x deer at 380 and 467m. Both shots direct centre shoulder. Put rifle away into hard padded case.

Got home, cleaned it, put it in the safe.

took it out again last weekend and shot @ 2x deer, 1 shot to one, and 2 shots to the other around the 300m mark. All 3x shots misses.

What could cause this ?

Im running RL26, and the only difference I could come up with was the temperature was around 16 when I load developed and up the kawekas the tempo was 1/0 deg.

Have checked all my loads for seating incase they bounced in the case and seating depth changed, I have checked my dialup for windage was at zero, and my correct strelok rifle was used.

Getting back to the range this weekend depending on weather, but hoping its still on zero at 100.
