Just to add more fuel to the fire.
Advice on the internet needs context. There is a lot of bad advice that gets around, or even good advice that can be bad advice if misinterpreted. I shoot Service Rifle Across the Course, Long Range, Palma, and Precision Rifle Series stuff. I was good enough to get my Presidents 100 Tab, Distinguished Riflemans badge, and this year have averaged around the top 1/3rd of the matches I have shot. I'm don't consider myself a great shooter, but probably better than most.
Every shooting sport has a ton of people that are still learning by experience, trial and error, and people that know more because they read it somewhere else. PRS and shooting sports in general are infested with people that do tons of questionable shit and get away with it, or experience some sort of success.
An example: You can load your ammo to unsafe pressures and still have it work. As long as you have 200 rounds where it doesn't really bite you in the ass...you can win a match with it. Or at least feel it helped you out. Ammo problems are very common at PRS matches, especially with hand loads. I watch shooters do this all the time. I wonder how many rifle matches have been lost because of Jewel triggers and dust? The same match that was lost because of a Jewel trigger was probably won with a Jewel trigger because someone is bound to have one that isn't going to fail at the wrong time. Just because it works today doesn't mean it's going to work tomorrow.
CLEANING IS PREVENTATIVE MAINTENCE.
Nobody has won a match because they cleaned their rifle, but matches have been lost because someone didn't clean theirs.
I was all onboard the whole "only clean when you absolutely have to" train until it really bit me in the ass at a match. I didn't clean the barrel on my first 260 Remington because I was like "Fuck it...it still groups...cleaning is stupid and makes my hands smell." I went to a 2 day match in a different state...and low and behold...sticky bolt lift. And my data didn't track. I'm hemorrhaged points. And it was just an altogether frustrating experience. I went from doing top 1/3rd at a well attended match all the way to the bottom half of a club match that had a higher proportion of novice shooters. The whole thing sucked because I couldn't trust my data, or my rifle. I'm wondering if maybe I messed up the ammo, or the neck tension, or if maybe it's because it's colder.
Feeling totally fucking lost at a match is a total bummer. Sucking for a whole weekend because you followed common knowledge from the internet makes you feel like a dumbass. And I am a dumbass because I had to re-learn the things I already knew from all of the NRA stuff. The NRA stuff really punishes being a dumbass at higher levels because of how competitive it is; if you save a round during one stage of rapid fire you have practically just lost the match. Same thing if you crossfire a shot onto a wrong target. Putting the wrong dope on is the same; shoot 1 string of 300 yards rapid fire with your 200 yard dope on and you've just fucked yourself from 1st place all the way down to 25th.
PRS/NRL is not nearly as punishing because you can make a lot of mistakes through the course of a day and still okay. I shot a club match this weekend and finished 9th of 55 shooters. I had one stage where I fucked up massively and shot a 0. And it isn't like I shot at the wrong target; I just got inside of my own head and didn't trust the data, and didn't put bullets where they needed to go. That was a HUGE fuck-up. Looking back at the stage and at how well everyone else did; that stage should have been an easy 4 points. 4 more points would have put me in 4th place...which is definitely good, but at the end of the day, anyone can look at a 9th place finish in a pretty competitive match and be like "that guy is a halfway decent shooter."
The bottom line is that matches are won by the best shooter who makes the least number of errors. At the higher levels it's more about fucking up the least amount than anything else. Making sure to take care of simple stuff like your rifle and ammo isn't going to make your good days much better; but they will make your bad days a whole heck of a lot less terrible. At least with shooting a 0 on a stage this weekend it's just because I suck at shooting and not because I failed to do something before the match.
Fouling effects pressures. Pressure effects velocity. Velocity effects data. I clean my barrel regularly because I care about making sure my data is going to hold up consistently over time. In a perfect world, I would like to only have to verify data once and be able to shoot with it the rest of the year. Barrel wear is a thing so there will be tweaks but those tweaks should be more predictable while removing fouling at regular intervals means I am seeing the effect of barrel wear and not barrel wear + fouling. And cleaning frequently means I won't have to clean as hard either.
Garbage post over.
