Factors that affect accuracy

[searcher]

Scope to rings contact. Rings to base, base to rifle contact.
Bolt lug contact
bullet tip uniformity
bullet base to ogive uniformity
case thickness uniformity
bullet weight uniformity

Just adding what could be made "more uniform" can take another page.......

- - - and we snobs who turn noses up at the spray and pray crowd thought shooting was as easy as align the sights and pull the trigger,

The OP has an impressive list of factors that need to be attended to in order to obtain reliably repeatable precision. More posts have added to the list.

Start with wind flags and build from there. Lacking them as #1 on the list of importance, the 'results' of anything else tested or tried is suspect, at best.

Correct, the next step is to divide those factors into groups and rank them in terms of importance.
Wind calls comes first

LOL . I wish I saw wind like that at a long range.

Who is @Beiruty? I’ve seen a bunch of your posts lately, yet would like to know if we have met.

I am sorry, I did not. I live in North Dallas, TX area.
We suffer from the lack of the availability of long ranges and sanctioned BR and F-TR competitions.

And I feel so much depends on the weather

Here it is, watch it all but the trimming part is around 9:30

After I watched one of Jack’s videos one time, I never tried to find a flash hole uniformer for the small hole Lapua brass. I’m sure others have a different opinion.

Honestly, my list would be much shorter.....things most get wrong or don't fully comprehend the value of. Believing the 'results' of testing proceedure(s) that are flawed right from their basic premise would come right behind wind flag use.

There's no hoodoo, voodoo or magic involved in this stuff. Sound basics and the application of common sense when testing gets you most of the way there.

Yes there are lots of engineers from civil to software .
But to which profession are you dedicated to ?

I think bench construction is the first after rifle & equipment.
The wooden benches with seats attached are the devil's joke !

 

[Fuj]

The amount of "high caffeine" coffee I drink before shooting....LOL

Guilty here. But it's a constant !!. I shot a match last year that
someone forgot he coffee pot. Not good....

 

[RickyK]

That list makes my head hurt !!!

4 targets in, perfect score so far, need to get perfect score on 5th with at least 3 x's to stay in the top 3 ..........

Hoping your buddies do good & hoping your buddies don't do better than you !

Get to 5th target so far 4, 10's with 2 x's....... Eyes hurt, neck hurts, sholders hurt, hands trembling gotta make that x, gotta make that x .......

Boom ..... It's a 9.....,

This is the biggest hurdle i face when shooting for score.

Yes, Sir. the worse is even aftermath of that 9. was it neck tension? was my scale off 3 kernels of VV? was it primer seated to deep? was it bad wind call? was it flinching? was it all combined?
