Zeroing individually- sub 30 mins w/walking

Zeroing in a class- sub 1 hour w/walkimg

-HOM matters

-target size matters. 5MOA target size is best no matter the distance ……and I’ve never seen a 50 yd zero person use a 2.5” target in my life

-Understand adjustment and target sizes or carry a ruler. Most zeroing takes forever because majority don’t have a reference to what adjustment is needed

-Trust the optic’s stated adjustments (unless it’s an EOTech)

-Always start at 20-25 for newly mounted optics just to get on paper and save ammo/time

-don’t zero until predictive shooting is done

- make small adjustments while going through a predictive model if it’s way off

-understand where different zeros came from……range limitations, time limitations and the inability to see realistic targets aren’t good reasons.

-the famous picture of a tgt with dots where all different zeros will hit at various distances is useless since it doesn’t take into condensation human error, human perception and human flaws (eyesight)

- no matter how much you try, justify, print ballistic sheets, use ballistic calculators or re-post the picture of what the different zeros do……you’ll never beat a 100 yd zero in real application (exception- dedicated rifle matches where MPB is ideal)

-the difference between a 100 yd vs. 100m zero is about the width of the bullet……..just doesn’t matter

-all 3 US sniper corps zero at 100

- you physically (and perfectly?) can’t be off more than barrel/optic relationship from contact distance to roughly 150 yds with a 100 yd zero

- all holds are in one direction with a 100 yd zero

- majority of people aren’t as low at 50 yds as the BC says with a 100 yd zero (perception/errror, etc)

-25/300 aren’t the same, 50/200 aren’t the same. For you RDS/irons people who think so just ask a scoped guy who can actually see 5 MOA targets at those distances and the impacts…….or just look at his dope card.

My recce rifle is ready for the next few month plus of scoped rifle and sniper classes. She’s a good one and hits 2 MOA targets at 600 with ease. Powered by @blackhillsammo

The Inventory 8 of 8 / Glock 19 KKM Barrel My sights My holster or a Safariland / Used 20-22 weeks a year for mil and Le classes and for civilian pistol classes. Used for daily carry. I’ve been using match barrels in Glock pistols for over 10 years now. I started using KKM’s somewhere around 2010 or 11-long before it become the popular barrel of choice it is now. I also used Wilson combat match barrels for Glock’s back when you had to fit them. I prefer hand fitting a barrel because I can make it even more accurate. I tell everyone my opinion is to shoot the Glock pistol stock and wait to get a match barrel when you notice groups starting to open up a bit. In my experience this happen somewhere between 80 and 100,000 rounds. A match barrel will not help you magically shoot better all of the sudden. All it does is hone good fundamentals a little more. The average difference that I have measured over tens of thousands of shooters between a stock barrel and a match barrel at 25 yards on an NRA B-8 bull is somewhere between 3-4 points or around an inch tighter- both of these metrics are with a 10 round group from the standing unsupported position / 3-4" group at 25 yds. (Standing unsupported) with any ammo.

The original DFP being used as my primary once again. This thing has stood the test of time. It’s been used overseas, loaned to students, and my number two for about 5-6 years now. No batteries- just a black EOtech type reticle on one power and MIL hashes in four power. The gun as pictured has 100 % hits out to 400 yds on B/C steel using Black Hills 77 gr.
