Iron sights would be a waste of time in my case.
My eyes are so bad the optometrist said not only do I need glasses, so do my firearms.
He's not lying.

Looks good, pretty darn good looking target. Toss out a couple lows probably due to bad rounds and you have a nice grouping. I love peep sights but wish I'd done more of it back when I had good eyes. Soon as I get this Country Music event that is being held on property located behind me and they all leave I'll give the peep sight challenge a go.

I do struggle a bit with old eyes. My post and blade days are history, but i can still function okay with peep sights when i wear 1/2 power reading glasses. That being said, things were getting pretty fuzzy by the end of that box of ammo.

Hey, don't be looking at me that way....it wasn't in my stash.
It came out of cuz's pistol bag. I asked if he was going to use 'em, was told to take 'em.

Oh the horror....oh the shame...oh the ignominy,
oh the entertainment of seeing what will happen at 200 yards.

I wonder if I have a big enough chunk of cardboard?

Wind from the WNW, my 4, at 3 to 7 mph.
90 degrees F, muggy and buggy. Skeeters are so annoying.
CZ 455 Varmint, Lilja sporter barrel, Mueller 8-32x44 atop a 25 moa rail.
40 grain Remington Golden Bullets at 200 yards, minimal mirage.
Box MV labeled 1255 fps.



Started out by adjusting the scope to fit the ammo and conditions.
Aiming at the top left notch of the ear of the steel,
adjusted until 2 of 3 shots punched the center flapper.



Then swung over to the sight dot and fired for effect

Low mv 1200 fps, Hi 1287, Average 1236 for 50 shots

10 inches of vertical, 8 inches of horizontal



The golden bullets weren't all that bad.
With the 1/2-1/3 rule, at 100 yards 3-1/2 inches of spread.
At 50 yards 1-1/4 inch of spread, at 25 yards 3/8 inch of spread.
Still more than adequate for popping rabbits or tree rats back in the palmettos and pines.

I think next trip I'll send some 22wmr.

West wind this morning at 4 to 8 mph, my 5 o'clock
90 degrees F, 100% humidity, CCI 30 GR Vmax 22 wmr


The 455 Stubby, new Feddersen 16.5 inch threaded 22wmr barrel



Looking at the target at 200 yards



What the chronograph recorded
Ballistic calculator says vertical should be 5.81 inches from those numbers



and the group of 50



5-3/4 inches of vertical, 7 inches of horizontal
Not a surprise with CCI 22 wmr varminting ammo.

Apply the half-third rule for rimfire

200 yards produces 7 inches
100 yards will show 2-1/3 inches
50 yards and 3/4 inch
25 yards for 1/4 inch.

Just found this. Try some Aguila std 40 rd lead, just makes subsonic but not coated. Has the same POI as GECO so I mix them. We've had so much rain the hayfield is higher than the 200 yard range targets so we cut thru the woods to 300 yards & so far are just shooting a 5"x7" rect plate & a 6" round gong. Will add cow bells & 3 & 4" spinners. Will give it a try when it quits raining.

Flylo, I've got so many odd boxes in the locker, this will last at least a year.
I figure one or two boxes a week of everything from Golden Bullets to Tenex.
Multiple flavors and brands of 22wmr and 17 hmr. Anyone who wants to try it is welcome.
I'd like to see other rimfire rifles from sporters to bench rigs give it a try.
200 yards for 50 shots really prevents cherry picking.
Add in chrony data and it's useful information for anyone testing ammo.

CCI 40 gr JHP was this mornings entertainment.
WSW wind at 7 to 10 mph, swinging from my 4 to my 6
455 Feddersen Varmint on heavy bags again.




Ballistic calculator shows 6.2 inches of vertical spread

The target with 50 shots at 200 yards
The real world produced 6.5 inches of vertical, 6.75 inches of horizontal.
Swinging tailwind purely kicks my butt.
Can't get a clean read of wind conditions downrange due to turbulence.

Stopped by wally world to pick up printer paper.
Walking back to checkout wandered by sporting goods
and spotted a couple of lonely boxes on the shelf.
The Winchester is just for entertainment value.
I've been meaning to try the A17 after hearing claims of accuracy.
We will see.

455 Feddersen stubby, Hornady 30 gr Vmax 22wmr mv labeled 2200 fps
Tailwind at 6 to 10 mph swinging from my 8 to my 4 made it interesting,
as did the weak round that dropped in so much lower than the rest.
The box may be labeled Hornady but it's manufactured by CCI, and it shows.

Ballistic calculator expects 12 inches of vertical spread,
10 inches of horizontal at 200 yards.



9.5 inches of vertical, 8.75 inches of horizontal



The weak round impacted just above the 5.5 inch mark on the horizontal ruler.
Audibly weak round compared to the others.

CCI A17 17 grain ballistic tips at 200 yards
Box is labeled 2650 fps
455 barrel block with set trigger on the f-class bipod and bags



Winds from the west to southwest at 2 to 5 mph



4 inches of vertical, 2 inches of horizontal
the best results on target so far

Ballistic calculator figures 3.1 inches of vertical due to mv spread
and 1.6 inches of horizontal due to wind

4 inches at 200 yards
1.3 inches at 100 yards
0.4 inches at 50 yards
0.16 inches at 25 yards

Impressive. Your calculated results mimic my real world results at 50 and 100 yards. My one CZ 455 American likes this round.

The half-third rule works.
I've been working with the chronograph for three years now.
Every trip to the range, the chrony gets set out front.
I have target results and chronograph numbers for 25, 50, 100 and 200 yards.
Group sizes and chronograph results compared to ballistic calculator predictions.
It was easy to see the the correlation between distance to target and trajectory spread.
As a result, I rarely shoot at less than 200 yards when at the range.
I can calculate an accurate target result at the shorter distances from my 200 yard targets.
A side benefit, the 200 yard range is never crowded.
Few are willing to make the walk down and back to hang targets.
As it happens I need the exercise.
