I've reloaded .223 and .223AI for so many years I've lost track, well over 50k rounds between target, varmint, competition and practice ammo. Each use has it's own parameters that I find acceptable or not. I would say given the equipment you are using those groups are going to be pretty on par with what to expect. There are so many ways to tweak ammo to improve accuracy and the same goes for the shooter and the rifle it's too long to list here. It comes down what do you need to be able to accomplish and how much time and money do you have to get the results you want. Once you start looking and spending the cost vs result of improvement goes up dramatically, nothing is free. LOL. Your video is very good at showing overall all 3 loads could serve functionally well. I sub'd looking forward to more content.

I am looking for a bullet trap for rim-fires, Do you know of any? Thanks

paper punching is so duull

Great groups Your loads are spot on 👍🏻Would love to shoot the can target were is it available? Iv got a Fac.Axis ll Precision .223 MDT shoots bulk Fiocchi decent sometimes 🤪. I don’t load yet will get into it inevitably Someday. Awesome loads👍🏻👍🏻and setup.

Great video and glad i found your channel. See you out on the range once it warms up a bit. I have alot of testing to do with my vudoo.

Good test - all tests have statistical issues, but Yours is better than many I’ve seen. For my competition (and hunting) I test several 4-shot groups over time. There are weaknesses in that testing also, but keeping calm I still find my go to-ammo. Really no surprises.

The velocity was low so I think the powder charge is low . That'll explain the high ES .

What rifle are you using?

What ammunition are you using?

Yup been there like so many others !

BYW. New subscriber.

Cool game bud. I gotta try it so I’m going to set up for this. What size are the steel targets at given distances.

Great Shooting Bud! Thanks for Sharing!!👍🏻

DO U KNOW ANYONE WITH A 17 HM2 lilja barrel on a p94s or cz457

Semantics, but you are not shooting a CZ 457. If the action is all left of it we should start thinking of a new name. It's a little "funny" as if we take what is CZ from that gun no-one can shoot anything. We don't call a car a Ford Mustang either if we change all the parts to bits from here and there only keeping the engine block? Engine=action, transmission=barrel, chassi=stock, steering/control=trigger is how I thought... Now that everyone is upset: It IS a nice gun and I like it! But I have the same issues with it as with many so called "Tikka T3" where barely even the action is Tikka anymore. It's like welding parts together into a car in the garage and saying it's a Ferrari. It might be good and nice but it's not a Ferrari...

...that was really interesting video, thank you!. I'm a target shooter and I suppose I should be interested in ES and SD's, but I'm not. My ladder tests usually start about 1.8grn below max and go in 0.3grn steps for .223. I'll usually find 2 nodes for accuracy, then I'll go 0.1grn either side and see how flat it is. Then is seating depth. Always amazed at how different rifles react to powder / bullet / primer / seating combinations!

I agree to an extent. its nice to have some kind of standard though. there is lotsbof rifles out there that won't shoot three shots as good as your rifle will.

I don't think that anything you do at the bench is causing the high extreme spreads. what I've seen over the last 8 years recording velocities, when you have the right load i.e. powder weight and seating depth, the extreme spreads are lower.

I see you attributed the low left to a charge weight error. I know you don't want to be too quick to call a flyer but being honest about flyers both ways is good. How many more shots to you believe it would take for that one shot to become apart of the group.... probably never would so it's ok to dismiss, IMO. Shooting new brass will not help with good ES/SD. Same with group size ES. Switching to a different primer can do good for ES/SD. Primers have a bigger impact than many believe, especially in smaller cartridges. Was the follow up group/s with your now once fired brass? Seems the SD is better in that one. Lots of ways to go about reloading/load development. And the needs of said load can dictate that as well. Like you said for hunting, may bot need all the trail and testing as many deer have fallen to iron site pie plate accurate rifles. First video I've seen on the channel and look forward to checking out more. I'm very into reloading, whether I know what I'm doing or just making myself ask more questions, I love to tinker.

I was out there at our local range the other day. Hope to see you there one day.

As a hunter I went to the store, bought what he had (Norma), tested and went hunting. If it hits it hit, if it misses it misses 🤭🤣.

Low powder case fill generally will cause higher ES , SD . The medium to max loads will generally have the best ES , SD

Can primer burn be measured? How about differences in primers from the same batch can that be measured by burn rate or burst force? Lastly primer metal thickness hardness weakness?

I did something similar with my 350 Legend. I wanted to try copper bullets, so I made some loads from min to max with two powders. First groups, min load, were high and right. As velocity increased, groups got tighter and moved down and left - same point of aim, no scope adjustment. Finally, second powder, mid range load, first shot dead center bullseye. Second shot, 4 o'clock touching bull, third shot between first and second, total about 3/4 inch, 100 yards. Good enough for me. I stopped right there. Why are lower velocity shots high? Why do the groups move left at higher velocity? Must be barrel harmonics, just a guess.

Those are excellent rifles. Best kept secret in the firearms world.... I have one in .223 as well. Shoots almost everything MOA or under. Handloads get even better. I do my load development in .5gr increments starting from the middle of the range and go up. I like having the velocity. I have no need for an underpowered load. Then seating depth etc.. Like the approach shown here as well. Redo this test with 30 cold bore shots... That would take days Im sure!! Nice work, thanks for putting this together.

Awesome

I suspect that 'flyer' in your blue group was probably (accidentally) loaded to minimum charge weight. I'll bet transferring it to the pink group would put it right in the mix. Just my $.02, - Jace

Love the approach. Makes you wonder how many lbs of powder get wasted every year with people chasing around 0.2g increments of powder charge with 3-5 shot groups.

I love that. Where in Oklahoma???

Every time I mention 20 shot groups when watching a rifle review I get flamed 🔥 But the truth is very few rifles can consistently put 20 rounds on target under 1 inch all the time @ 100 yards. It’s just a fact.

Very cool stuff! I agree 110% about shooting groups and trying to hit a tiny circle is 2 different things altogether! 👍 Good shooting 👏 Is there a place a guy could get ahold of those targets you use in this? I absolutely would love to try that sometime!

I've known two people who bought Springfield 2020 rifles. One returned his the same day due to poor accuracy while the other suffered for several months before dumping his. The rifles look great and if SA had put an extra $100 in them to make them accurate, they'd have a winner on their hands. They blew it.

The rifle was verified with your first target of 3 shot groups. The multi group shot test is flawed in ammo lot variance, loading variance, heat variance & shooter fatigue. There are too many variables to quantify with that method. Outcome- waste of ammo.

Yeah youll have that, my wife beats me like a gong..... best regards Steve

The key words in this hole video is how is shooting and it takes a large wheel barrel full of of powder to burn to be that quality of a shooter.

Great point and explanation. When I saw your multiple three-shot groups, I was hoping you would combine them 🙂 . I'm a bit obsessed with accuracy and I've noticed pretty much what you've talked about. I've tried my best to eliminate The effect of parallax by adjusting my scope the best I can, but I wonder how much of a part it plays as I move from one target to a different one if my head is a quarter inch in a different spot than the previous target....... That's been my thesis of why my groups are grouping in different spots on different targets lately anyway.... Working on trying to figure out if it's that or what. Anyway, thanks for the video!

They are all bull s&%T Had a Weatherby Van in .300win that wouldn't hit a barn if you were standing in it. They wanted $200.00 to "look" at it.. If they found a cartridge to make sub MOA they would call it good and take your money.Moved on from Weatherby and never looked back.. Tikka and CZ.. Those rifles, at least mine are sub MOA with about everything u feed it.. Not some one trick pony.. Colt CBX precision.. Could not get it to shoot Sierra 168Gr over 4064.. Now if you can't get a 308 to shoot with 4064.. Might as well get rid of it. Colt used a Berger match load and called it good..

Thanks for coming out OK Rifleman! I need some training on scoring the cards! Ron

I agree 100% 👍

Something is wrong with your loading process. You should never get that high of es/sd. I also use Sig brass, it is excellent stuff. There are no anomalies with it, in regards to capacity, which would cause a difference in pressure, which has a huge influence on velocity. I'd check your scale, and probably use a different powder. I don't know your loading process, but something needs to get fixed. That rifle would shoot much better, if you get your loading process fixed. Trust me on that one.. I could easily tune that rifle to shoot sub moa all day long..

How far to target

Good video

I shoot 5 shot groups at 50 if it’s good I shoot 10 shots at 100yds but the a low sd number with 10 shots seems to work well too. I watched this on one of eagle eye early RUclips’s

There is a way to reduce cold bore shots. After seeing this I started to do it and my cold bore shots got less and sometimes non existent. I hope this work for your rifle. Make a video to show us. All the best with your new channel. ruclips.net/video/-DJfpCvVLZg/видео.html

Nice targets, I am going to copy the idea for myself to practice with my air rifle at home. It will make it more interesting than to just shoot the old targets.

I really like the Winchester model 70, of all eras, but they do need to be fine tuned, to meet that 1 moa all day long criteria. Hopefully you removed the crappy hot glue bedding, Winchester used on that rifle? That is the number one thing I do, and then I properly glass bed the action to the stock, and then freefloat the barrel. A nice heavy barreled Winchester model 70 should drive tacks, shot after shot, when using a good load. This should not be stated, but all the mechanicals have to be right on these rifles first and foremost. That also includes the type of scope mount you are using. Blue loctite down the bases and make sure the rings are in perfect alignment. If not, bed the bases or lap the rings. Use a proven scope, and kick back and put those bullets into the same hole. I bought a nice heavy barrel varmint 308W, 2 years ago, and had to go through it. As they aren't perfect from the factory. It easily shoots .6 moa for 10 shots, religiously. Yours is a 22-250. Those are very inherently accurate. My 1984 featherweight 22-250 shoots "moa all day long" as well. Its all in the mechanicals of the rifle and load.

Some insight... your lot testing and ammo combination shouldn't be judged at 50 yards / meters. This is why lot test centers will use 50 meter results to further test the same lot at 100 before making judgment. In my expirence, SK at that velocity 1050-1060 will produce more vertical spread and less accuracy. You may find, this is where that particular lot of Midas + may have a tighter cone of accuracy at longer distances.

Nice job trying to help us understand sample size. Referencing the Hornady boys is a plus!

Great info thanks 👍
