PRS Fundamentals

I totally want a 300WSM... that being said, it may be too much boom to be ideal for PRS. Spotting your misses is really important, so most folks are shooting a 6mm somethingoranother or 6.5mm.

Oh ya, and do not worry about the age. I started rimfire PRS at 52 and shot my first centrefire PRS this summer at 54. It is not physically very intense... and it is also a pretty understanding community and accomodations have been made at the competitions I have been at for people with mobility challenges that can't kneel and stuff like that.
I'm now thinking I'll get 2 different calibers.... uuugghhh... this is how it started last time!!!

I had a 6.5x47 and absolutely loved it, but it seems like 6.5CM is what all the cool kids have these days... haha.

Still thinking a .300WSM for a hunting gun, but I guess if I'm not compromising maybe I should go 300PRC for more punch should I ever happen across something that wants to eat me. I dunno.

If you want to shoot Centrefire PRS a 6.5CM is a good place to start. 6mm is what almost all Pro Shooters use in the top 200 in the US.
300WSM is legal but why beat yourself up like that?
Shoot what you have is better than not shooting at all. :)

I'm starting from scratch, so I have a clean slate.... could do 6mm too. I'm not wanting to beat myself up with the 300WSM... was just hoping to simplify my reloading bench and knowledge.

You're right though, just getting out and shooting is better than nothin.

I am getting into PRS shooting 6.5CM because that is what I could get relatively cheaply and what I reload for already.

When I rebarrel, I will look at a 6mm... which one I dunno. Likely 6mm Dasher or 6 GT. As reloaders, we have some really cool options!

Just read about the dasher last evening… that’s my current #1 option… couple of factory brass makers, easy on the recoil, and something like 40% of the PRS leaders use it. Tough to go wrong.

I have been writing articles a fair bit for the website and thought I would share this one here.​

This is just a portion of the article.


What Separates Elite PRS Shooters from the Rest?

When it comes to Precision Rifle Series (PRS) competition, shooters are often working with high-end rifles, top-tier optics, and carefully measured hand-loaded ammunition. So what truly sets elite competitors apart from the rest?

One word: Wind.

The ability to read wind, interpret its effects on a bullet, and make rapid, accurate adjustments is the skill that separates winning shooters from those struggling to land consistent impacts. Unlike elevation adjustments—where a shooter can rely on hard data from ballistic solvers—wind is constantly changing, unpredictable, and requires real-time adaptation.

Even the most precise rifle setup won’t matter if a shooter miscalculates wind. Mastering wind calls is what turns a good PRS shooter into a champion.


Breaking Down Key Wind Indicators

Reading the wind isn’t guesswork—it’s a skill built on observing visual indicators, understanding ballistics, and applying corrections quickly. Here are the three most critical wind-reading tools every PRS shooter must master:

Mirage – Nature’s Built-In Wind Meter

What it is: Mirage is the distortion of light caused by heat waves rising off the ground. It can be seen through spotting scopes and rifle optics, especially at longer ranges.

How to read it:

  • At low magnification, mirage appears as shimmering waves above the ground.
  • At higher magnification, mirage can give clues about wind speed and direction.
  • If the mirage is moving straight up, there’s little to no wind.
  • If the mirage leans slightly, the wind is light (under 3-5 mph).
  • When the mirage starts to boil sideways, the wind is strong (over 10 mph).
Pro Tip: Learn to observe mirage at multiple distances along your shooting lane—it’s possible for wind to be blowing in different directions at different points between you and your target.

Vegetation Movement – Reading the Terrain

What it is: The way grass, trees, and dust move can give quick and reliable wind information at a glance.

How to read it:

  • Grass and light brush movement indicates wind under 5 mph.
  • Small tree branches swaying suggests winds between 5-10 mph.
  • Heavy tree movement or dust blowing typically means 10+ mph winds.
Pro Tip: Train your eyes to spot terrain-based wind indicators quickly—they give immediate feedback on changes in wind speed and direction, especially when switching targets.


Bullet Trace – Real-Time Wind Feedback

What it is: The visible vapor trail or disturbance in the air caused by a bullet’s movement through the atmosphere. Bullet trace is easiest to see through a spotting scope but can sometimes be caught through a rifle scope with proper magnification.

How to read it:

  • Watch the arc of the bullet’s flight—if it drifts left or right more than expected, that’s wind pushing it off course.
  • Compare your shot’s impact to your intended hold. If you miss left or right, adjust accordingly.
  • Use your last shot to make immediate corrections—elite PRS shooters are masters at adjusting wind calls between shots.
Pro Tip: Team up with a spotter whenever possible—having someone else watching your bullet’s flight path can help refine your wind adjustments more quickly.

The Challenge: Wind Calls Take Experience & Practice

Unlike dialing for elevation, where data from a ballistic solver provides exact solutions, wind is dynamic and requires real-world observation and fast decision-making.

  • No two ranges are the same – Terrain, mirage, and obstacles can make wind act unpredictably.
  • Wind can shift mid-stage – PRS matches involve multiple target engagements, meaning shooters need to adjust between shots.
  • Experience builds intuition – The best PRS shooters develop a feel for wind over time, making their adjustments faster and more accurate.

I have a lot of downloads built to if anyone is interested.
 
Been looking at getting into some matches for fun, maybe starting with the rimfire. Could anyone explain the divisions, it seems self explanatory for the most part but if you have an aftermarket chassis on an otherwise factory rifle does that put you in Open? Signed up on Practiscore and been poking around looking at what is coming up this season but have a bunch of questions.
