I have been shooting SK LR, Match, Center X and ELEY team and match. Just with the supply of ammo. I am having to lot hop. What would you say you would want your ES to be for rimfire. I’m going to try to do some lot testing in the fall.
 
My match ammo is all 25 or lower across 30+ round strings. Mostly eley, but some SK long range match. I have a lot of center X that is around 30 and shoots great.

I had 3 lots of tenex once that would all be 15-17. But they did not group as well as the other lots I was shooting.
 
Curious is there any method to lessen the spread. Would keeping the ammo in a more controlled environment such as an ice chest Before shooting make a difference? Asking as I have experienced major spreads when the box is left in the sun.
I try to keep my ammo between 70-90 F. I use a soft-sided lunch "box" with nothing, ice packs or USB hand warmers depending on the temperature.
