If I wanted to pick the most demanding shooting sport it would have to be center fire Silhouette. Offhand at 547 yds with a 10 lb rifle is impressive. At least it seems that way to me.
It's hard for some to accept, but when I see PRS I am like "meh....." It simply doesn't interest me. Just like when I shot Highpower. I didn't stick with it because it didn't interest me.
That has nothing to do with the difficulty and skill required to be competitive in either.
I get excited about shooting small groups and high scores at 1000 yds. Others find that boring. That's okay.
There is no wrong answer, until someone says "X" takes more skill than "Y". BR seems to take the brunt of that, but there are lots of guys who give it a try and then quit when they realize how difficult it is to be competitive.
Like I posted earlier, if you hand someone a good LRBR rifle that tracks well and give them a finely tuned load, they will shoot well in good conditions. But that isn't a proper comparison. Give someone a rifle, the rests, then brass, bullets, powder, and primers. Then have them go shoot a match in varying conditions. That might be a fair comparison to a BR shooter showing up for their first PRS match.
It's like putting a newbie behind your carefully tuned and doped long range hunting rifle, telling them what to dial for drop and wind, then having them shoot an animal at 800 yds. In this scenario it isn't the trigger puller who is the long range marksman.
In my case, it took me a year before I stopped always being at the bottom when I started LRBR. When I came back after a 11 yr gap my path was similar. Now with the two matches where I shot NRA Highpower--with about three times the shooters that were shooting at the LRBR matches in that area--I finished mid-pack both times.
Then again, I didn't grow up shooting from a bench. I grew up shooting offhand and from field positions. Whether it's with a shotgun, handgun, bow, or rifle; I tend to shoot decently even when I am not in practice. I'll bet there are a LOT of folks here like that.
However, to be competitive with any of those aforementioned shooting disciplines takes a lot of "deliberate practice." Just being decent when we are out of practice isn't an indicator of the level of effort required to be competitive.
There is only one shooting sport (LRBR) where I have tried to compete at a high level, and to go to the next level I need about triple the deliberate practice that I am doing now.
Now I like and respect
@rhovee a great deal. However I will never agree that PRS is more demanding than LRBR. It just different.
Sorry for such a long winded reply......
