My rifle shoots 1/2" groups @100 yards all day! Really? Prove it.

wkoop, that is some great shooting with a very interesting load.
Enter it into the Varmint post and it will "on the board". { never mind, you already beat me to it }
congrats.

The load gives up 400 fps off a top load but keeps the barrel cooler while gopher shooting. Pressure is still close to max due to the powder speed and I check every case with a powder checker on my turret to make sure I don't double up. The load work up showed I could have gone to 13.5 grains but 12.9 is where the accuracy was. It also leaves a nice safety factor in there too.

With a charge that small, have you considered weighing the charges just for this pure accuracy test?
Of course you will need a scale capable of seeing under 0.1gr. most reloading scales can't.
With a 223, 0.1gr variation can show up on target. The Lee powder dispenser works very well with flake and ball powders but it will vary a bit.
doesn't take much.

I've got a j scale that says it'll do +- .02 that I use. We just grabbed 25 rounds out of our gopher stash from last year to see how we could do. Now that we are so close I'll weigh some out and see if we can make it. The lee disk (set up as a double) gives me +- .01 or so. Not bad for the speed upgrade it is over weighing for the 2000 rounds I load every year for our gopher shoot. The load holds Moa or less past 200 yards but after that starts to open up, likely due to velocity variation that doesn't show up as much at 100 or 200.
Jerry,
I use 21.5 gr. Blue Dot in .243 Winchester loads with Nosler 55gr. BT's and the accuracy is quite acceptable. This, despite the less than ideal load density. Velocities are very consistent and average around 3,100 fps.

Not quite
So I didn't pull it off, but I'm so pleased with the first group I'm posting anyway (as this rifle will likely have to be pawned before I can fire 5 more groups of the now refined load). Also the conditions were less than ideal, I had to shoot at one of my employers gravel pits as my range membership has expired and no extra cash to renew. The snow was a little deeper than I thought where I had to shoot from (down in the hole as the boss says), about a metre.
The rifle started life with a bit of a handicap, the chamber was very rough. I didn't send it back because it looked like it was going to shoot better than 0.75" at 100 yds. I was at the range to test my final loads and went to warm the barrel up a little with some loads that didn't make the grade. When I had to tap the bolt open !!!!!, what the hell, that load wasn't on the ragged edge! I fired one more and had the same result. What I discovered is that if you let someone else fire your rifle make sure you look at the ammo first, turns out it was a little corrosive. This is the first time I fired it since I polished the iron oxide out of the chamber and throat. I'm pretty happy with the results.
First the rifle.
Now the target.
The center is approx 0.400",
top left and bottom right are approx 0.600",
bottom right is approx 0.900",
bottom left was rushed as my balls were on the snow with only two thin layers of cotton between them, approx 1.300", but remove the called screw up and it's 0.750".
The load is 178 A-Max,
IVI brass,
Winchester primers,
H4895
The charge weight was center, 38.3gr, two right 38.4gr, and two left 38.5gr, COL 2.800"
Too bad we aren't counting best three!

I wonder...I don't think it wouldn't be any harder assuming there was no wind and you could find a factory load that could group 1/2 moa or better. You know I've thought about getting a .22lr for a long time and when you get down to it, it's the ammo that makes me stay with centerfire. My rifle always likes my ammo, it may take a while but I'll eventually get it right. lol, I can't decide what I like more the shooting or the reloading.
The fact is this is as much about the ammo as it is the rifle. I'd guess with all the competition using rimfire you could find good ammo, but I'm betting your locker will be full of partial boxes of .22lr that didn't make the cut.

I decided to take the challenge today and although I was happy with the results, I did not make the cut.
My rifle is built on a very old L57 Sako action that I bought 15 years ago for $100.
It is now chambered in 6mmbr with a Rob McLennon 4 groove cut rifled barrel.
The walnut stock is of my own making as is the entire trigger assy. which has a 1/2 LB pull.
I built this rifle to shoot paper, water jugs far off in the bean field and ground hogs.
The loads I prepared today for this challenge were Berger 88gr LD seated .010" into the lands and propelled by 28.3 gr of H4895.
The paper target is showing 6 groups but since I didn't make it anyways, who cares.
1-.510
2-.320
3-.560
4-.350
5-.630
6-.460
Maybe another day...

Today was the day my second attemp. Perfect light perfect conditions light breeze in my face.
222 tikka SV
Load 19.5 gr 4198
52 fb Bg
+6 9-12 km south wind.
I did not have to pull the 6ppc out. But I thought I may have to lol
I shot into it. Range ver very close to 100 y plus minus.
My 3rd group was too close but made it into the .4s.
Tikka 222 with a vx 16x scope
The gun. I shot 6 under .5 today
My first group I shot on the bottom of the paper on target 8 and 7 ( should say) but I never counted. It was under .5 as well in a clean pipe. I shot 7 and 8 first to foul the pipe.
They don't count. Never were going to. That's why I shot them first to leave 1-6 open

Yes I shot my 8 and 7 target first to foul my barrel.
But than I shot strings 1-6. Does this not count ??
Lol
I only claimed 1-6 ! If not Lol I will do it again tomorrow of the weather hold true.
And I never said I could do this day in day out. I failed my first 2 attemps. Posted one fail never posted the second. It all came together today. Conditions / mood / trigger.

One was .490 the other .577
But they were fouler groups. Clean barrel.
I really never put much effort into my 7 and 8 groups. I was almost tempted to just rip 10 into the bank.
My 222 shoots well for about 90-100 rounds and takes 5-7 to foul in for group shooting.
I shot 7 first than 8 settled in.
Like I say. You can't count my siter shots that's why I never mentioned them.
When I shot benchrest you have a siter target as part of it. U can shoot that target anytime.
I knew my 222 would shoot .5 or under. Have shot some really tight groups off concrete benches it almost gives my br 6ppc a run. Sometimes..
