I've definitely considered getting a small press to take with me, my beam scale, trimmer, etc. basically everything I would need to do load development at the range. Would be nice to shoot 3-5 rounds, go load some more while the barrel cools and do it again. We have an office/shack at the range that I could set everything up in if I wanted to. The range is only 20 minutes away though. I'll usually do load work up for more than one rifle at a time. Bring some pistols and/or rifles that already have loaded developed for them to shoot while barrels cool. When I'm done with the data gathering, which can take the majority of the day when you're doing it for 2-3 rifles, I'll load it all up and go home. Clean brass, prep brass, load it all up based on the data I gathered and spend the majority of the day shooting the next time too. If I was doing one rifle at a time it might be beneficial to just have stuff there but I try to make sure I have enough new blood in the safe that I always have something to work on. Or, with components the way they are now I might have to work up a new load for an existing rifle because I can't get a bullet or powder for it. Before I got married (again) and had a baby I'd be at the range at least once a week over the summer. Now I have to fight just to get time to load.
