Posted this before...nothing makes me feel better than knowing my zeros are GTG.

This time I took a sampling of my stash to confirm the different POI and with the suppressor and without.

Wish I had a 200-400m range close to confirm my dope sheets but it is what it is.

Dew - I did the exact same thing my back yard but I only shot suppressed because of the close proximity of my neighbors (none close to my berm area)....300 Blackout thru my Ruger American Rifle with one of my Omega’s attached....208gr A-Max makes a SMACK when it hits the dirt berm....Love that sound....

Even more important than ensuring it's clean.

Did that two weeks ago!! No better feeling than first shot perfection (or close enough)

Hit up a 200 yard range and was very happy that my 50/200 was damn nuts on at both after a year going in and out of the safe as needed. For reference Colt LE6940 with an Aimpoint Comp M4

Also sighted in my “backup” a BCM 20” A4 with irons.

Both now wiped down with a few patches through the barrel and GTG for whatever may come.

Yep. Put a red dot on the truck gun and sighted it in today as well.

Off and on, for years I fought with keeping a consistent zero from my AR15 with an 18" barrel. I reset the zero stop every few months -- almost always up and down, and within a 1.5-ish range. Frustrating, as it occurred with both the rifle's first and second barrels. Great barrels, too. The first barrel was definitely sub-MOA, roughly 3/4 MOA capable. The second barrel was even better, with .5 MOA capabilities for the right factory ammo -- at distances out to 500 yards.

The final straw was at a 2-rifle precision match, where I generally nailed targets while shooting from barriers, but shot generally high and sometimes low from prone. A buddy on my squad suggested my cheek weld was inconsistent. He was right. Dagnabbit.

I had a Magpul UBR stock on that AR. Nice in principle; not so great in my practice. After considering that the face in the mirror was the problem, I first tried another lower with a Magpul STR stock on the 18" upper -- my inconsistent verticals almost went away. I then tried a third lower with a Magpul PRS stock -- at which point my inconsistent verticals disappeared. So I yanked the UBR stock and bought another PRS stock. I'll never use a UBR stock again, as it just doesn't work for me.

I find that rifle zeros don't change if the following occur:
- The shooter has a consistent cheek weld and follows the fundamentals of marksmanship while breaking the shot. Probably the most important factor.
- The rings or mounts are solid to the rifle. And of course, the sight height remains constant.
- The optic is solid.
- The same ammo is used.
- The rifle has not experienced shocks which exceed the design parameters of the rifle, mount, and optics.

I now have both bolt action and AR15 rifles which have held their zeros for years, and after many thousands of rounds down their tubes.

The cheek weld was something I had remind myself.....STUPID ME

I now go through the same ritual while shooting everytime to ensure proper repeatable cheek weld.

Not sure how I forgot this but at least I fixed it...

In the last few days I checked the zero on a few guns. This is more for deer hunting than whatever else. The two guns were my Browning A-Bolt in 284 Win, and my Knight 45 cal ‘Elite’ muzzle-loader.

Next weekend is the 1st IL gun deer hunt. I’m still thinking about getting to MI before the firearm deer season closes.

Of the various guns I have, it’s usually a fairly small rotation on what’s sighted & ready to go. I have a few in different categories, from 22 & 17 HMR on up.
