I would encourage any PRS/PRL shooter that wants to up their LR game to go shoot some F class matches. Some ranges will set up an area for muzzle braked shooters so you don't even need to change your rifle.
At the Rattlesnake range in S. WA, quite a few PRS/NRL shooters come out and practise/compete out to 1000yds (distances possible include 300, 600, 800, 900 and 1000yds). No better way to confirm dope, wind drift, load tuning, optics and rests. Each relay/distance will allow at least 17rds on paper and every shot is marked so you know exactly where you went.
Ranges have flags so there a way to compare wind and the actual affect on the bullet.
The PRS/NRL shooters are a great bunch of guys/gals and always leave with a much broader understanding of what is possible for LR accuracy, consistency. The many popular flavours of chamberings and bullets get tried.. even some 7mm and 30cal ELR boomers come out and play.
There is a real world comparison vs F Class set ups and options. pretty hard to debate scores and plot sheets.
To really improve in LR shooting, wind reading is paramount but you also need to have a set up with a very narrow cone of accuracy. For many, that is hard to test and rocks/gongs will not tell you all that you need to know. F class allows every shot to be marked and you have the time to make notes on the shot vs conditions... this is plotting your shots. Over time, you will see trends that might explain and address issues with current tuning and rifle set ups.... and you have the number of shots to allow for testing during the relay and compare the effects.
Ever wonder what 0.1gr of powder can do to your load tuning at 1000yds? with as many as 30rds in a 1000yds relay, you can do alot of testing.
Both F class and PRS use very capable gear but the approach to accuracy and LR tuning is quite different. Shooting on paper and getting real time feedback can prove to be very enlightening..... and humbling.
But then you know... and thus can improve.
