How much experience is needed to be able to participate in this? I'm a total newbie but would be very interested in attending the training portion.
I specialize in newbies (and also cater to experts). I've taught many Grade 9 courses in 30 years of high school edumacation so I've adapted my delivery to the newest of beginners to the LR game.
Speak to any of my client shooters in our community since they too had to get their start somewhere. Let it be me to gets you going. You see after excelling in Battle School (PPCLI Wainwright) many years / decades ago... I promised that I would remove all the "Suck" from range exercises

and ensure that all shooters have a great time as humanly possible on the range. My delivery and demeanour would be fun and lighthearted... except when I get "swiped" by a loaded-readied .223 carbine on the firing line at CQB
The Saturday program is designed to ease the newbies into the world. Then in the afternoon we do a "walk back" where we shoot some booolits at 100m and progress to 600m. All this while you familiarize yourself with the local conditions, your ammo, your rifle, and you will see your confidence levels rise. That's the intention. Unless you bring TWO rifles (recipe for failure...) to sight in or you bring gear that is (in the words of my deceased Italian Father-in-law, "Gooda Pa Shzt!") LOL
Some fzckups that I've seen on the practice mound:
* Shztty cheap Zhinese scope rings (airsoft quality)
* soft-as-dog-crap ring screws and cross bolt ring hardware
* Loose and improperly torqued base screws (at least 15-20 inch pounds, please)
* Cheap szht scopes that crap out once you start making turret adjustments (cheap gears made of plastic)... Best $$ of the buck: Bushnell 10x 40mm Mildot for $300 give or take... most reliable for the money and perfect for our game up to 600m
* improperly dressed shooters for the weather conditions (overdress with rain gear, and keep a spare set of clothes in the vehicle)
* Save your sheckels and buy quality... I've seen cheap back pack straps pull apart on the move to a new mound
* Ammo cans.... leave them in the vehicle... they are a disaster waiting to happen... transfer 50 - 60 rounds to your rucksack
* Cardboard / factory ammo boxes- always invite the rain, and results in a shzt show... spend $6 and buy plastic 50 round boxes at local gun shop
* tinkering with your factory trigger... leave it alone. Shoot it for a year, then bring it to your local expert
So there... a partial list of what - not - to - do and have TT laugh at you (lightens up the mood) on the firing mound!
Folks, shoot lots and lots of my matches LONG before you show up at the Meaford LR Steel Challenge.... I witnessed many, many shooters with blinged up rifles, scopes, hard cases, back packs that Labour Day weekend. They showed up in fancy vehicles ( most common from the GTA, just like at Blue Mtn where I was a lifty for many years ) and man did I ever call it right. I was RO at Stage 1 and Stage 9, and did I ever witness more fzckups in 2 days as a RO. I spoke to many of them; inviting them to my PR matches and many of them were never aware of PR matches around Ontario.
Learn to drive before you enter the Monaco/Indy/Daytona/ Grand Prix races....
So, does that put things into proper context? Learn with me and I'll get you to the championship levels
