You want a first-sit buck?

📅 Historical data
☀️ Verified daylight movement
🦌 Fawn backdating (The 70 Rule)

Alone, each one helps.
But when all three align?
You’re no longer guessing — you’re striking.

This isn’t about hoping a buck shows up.
It’s about knowing why he’s there…
…and when he’ll walk past that vine.

👉 Most hunters are missing one corner of the triangle.
And that’s why they burn out a stand after five sits.

Don’t manipulate the deer. Track them.
Use their behavior against them — naturally.

🔸 The 70 Rule is more than a date on the calendar.
It’s a system for killing bucks with less effort, more precision, and clean, repeatable data.

📕 How to one-sit Kill a Mature Buck: Using The 70 Rule

So why run over 100 cameras for more than 10 years?

Simple:
📸🦌📅 To get to know my deer.

Sure, the chart I posted might’ve made you smile — but it reflects something serious I’ve learned after thousands of hours in the field:
Up to 84% of natural, daylight deer movement is repeatable year after year…
as long as you don’t mess with it.

Of course, major factors like habitat destruction, flooding, or human pressure can throw things off. But in general, deer — even mature bucks — are creatures of habit.

And in my experience, the more you try to influence a buck (with bait, calls, or synthetic scent), the more you interrupt that pattern. It doesn’t spook him outright… it just adds chaos to a system that was once predictable.

Especially with big bucks.

They’re not like other deer. Mature bucks are already less repeatable by nature. Even at night, they’ll skirt food edges or stay downwind of hot zones. The more you push, the more they slip through your fingers.

Now let’s be real — any brand of deer lure can get you a great trail cam picture. But here’s what I always ask myself:

Was it 70 yards from his bedding line? Maybe 300?
Did I “pull” him from a shadowy fallback route…
or did I find his true daylight core?

Was he looking for estrus data? Checking scent trails?
If I contaminated that with foreign smells or preorbital gel, will he know exactly when to come back to breed…
or will he show up scattered, random, and two days too late?

I’m not telling you to ditch attractants.
Use what works for your property.
But I am pointing out a relationship I’ve observed over the years — a direct connection between influence and efficiency when it comes to building high-odds hunts for mature bucks.

If your setup pulls him off his natural loop, you might get the pic.
But you might also miss the only clean window he would’ve walked in daylight — if you had just let him be himself.

When in doubt, let the data come to you.
Don’t pull bucks. Find them.

♥️ This is the heart of the 70 Rule Kill Funnel — a simple way to take all the chaos of the whitetail rut… and narrow it down to several high-odds hunts.

It starts by either finding fawns or backdating fawn births using the 70 Rule.

That gives you a true 2-week rut window, based on biology — not moon charts 🌖 or guesswork.

From there, I use historical trail cam data 📆 📸 to find repeat buck appearances. When timing lines up across multiple seasons, patterns start to emerge — and suddenly, you're not just hoping for daylight movement... you're expecting it.

It’s not bottled magic. It’s not bait 🌽 It’s knowing where and when to make your move.

Some guys get trail cam pics of a #Daywalker and think they’ve patterned that buck the first year they found him. 
But after more than a decade running 100+ cameras, the REAL pattern is crystal clear. Discovering it was my path to repeated high-odds sits. 🏹 

🦌 Year 1: Just a 2% chance of a daylight encounter after the first trail cam pic. Most bucks vanish after one photo—sometimes I never see them again.

🦌 Year 2: A solid 39% chance for encounter IF he shows up the same week as last year AND I’m waiting. I’ve killed many bucks in Year 2 when I didn’t have another play. 

🦌 Year 3+: If a known buck repeats for 2+ straight years on the same week I’m in position. I have a personally proven 61% chance of a daylight encounter on a SPECIFIC mature buck—and often, a ONE-SIT kill. 13 now in total. 

These are repeater bucks. They are the bucks that come back each year around the same time — and they’re the REAL key 🔑 to setting up high-odds sits. 

I have found that less than 50% of mature bucks frequent the same thickets at the same times year-to-year. Not all bucks “repeat” but when you find one — you found GOLD 💰 📆 

👉 “If you’re hunting hot sign, you’re a day behind.”

 Often those buck pics you get are of him leaving the area. Not arriving.
