This topic is obviously split from one discipline to the next. Most of the F-Class and High Power shooters (and LR BR shooters for that matter), have never shot short range benchrest, and vice-versa. There's a big gap in how LR benchresters prepare compared to SR guys. There's even a gap between SR score, and SR group shooters. Most score shooters preload now, due to the 30BR, or other variations of short 30's. I've shot some 600 yd BR, a lot of SR score, and a lot of SR group, and this is my perspective.
How many of you make powder charge and/or seating depth changes between targets? The only accuracy discipline that I know of where almost everyone loads, and tunes as they go during a match is SR group shooting. Group shooting is a tune up contest, as much as a wind reading contest. If you've never witnessed what an extremely well tuned rifle can do in the wind, you probably wont believe me when I tell you it can defy logic. The bullet leaving the muzzle of the untuned rifle simply drifts further than the tuned bullet. I've been lucky enough to have one great barrel, and a bunch of good ones. The good ones don't do anything stupid, but the great ones cut the wind like it's not there most of the time. When it gets snotty, you don't have to hold nearly as far as with the good barrels.
I've had way too many non competitive barrels to say that they're all OK. I've personally chambered barrels, shot less than 50 rounds through them, and deemed them DOA. I'm not talking about bad shooting barrels here, heck, most would be smitten with them. But the precision required to be competitive in SR group is ridiculous. There are shooters in the Group game that chamber (or have chambered) upwards of 20 barrels each year, while shooting less than 5000 rounds a year. Many of these barrels only see a few rounds, only to be tossed in the tomato stake pile.
When it comes to bullets, I make my own, and have made probably as many bad bullets, as good ones.


Over the years, I've refined my process, and as such don't make many bad ones anymore, but I have faith that I can still screw it up. I don't believe in magic, but great jackets can increase the probability that you'll end up in the winners circle on a regular basis. Put great bullets together with a great barrel, and watch out...
