I'd go through all kinds of wasted effort and it would shoot an awesome 3 shot group. I'd make an adjustment and dejavue all over again.

Finally came out one day and just sat down and shot FIVE with no changes and three looked awesome, the other two were like a gorilla fired them. Up until then I was convinced Lightfields were the most awesome slugs on the market.

I always let the entire gun return to ambient temperature if it starts to warm up even 5 degrees.

I use a laser therm gun to keep track of barrel temps.

When I'm hunting the FIRST shot is the only one that really counts. They won't stand still for practice and warm up shots.
