I have several 22-250's and love them all, they all shoot dime size groups or under at 100 yards....I have shot plenty of quarter size groups at 250 yards....never thought about an Ackley in a 22-250....maybe I should...because of their twist in the barrels, all of them like a heavier than 69 grain pill.....They are amazing little rounds....

Foxhunter - Sounds like you love your 22-250, what grain bullet do you shoot in yours??

Notsams - We need pictures of the 22-250 AI.....please post them.....would love to see a work of art.....

I have begun to test the 22-250 AI. I am using Federal 22-250 brass to fire form into 22-250 AI. Rem 9 1/2 primers, H4831sc powder and 80 grain nosler custom competition bullets. 3 shots thru the crony showed 3300, 3303 and 3306 fps. The rifle shoots good but I am going to try some other powders to see if I can get more velocity with less pressure signs. I have shot groups at 1000 yards  so far and if the conditions are right I am going to try out to 1300 yards this weekend. The scope is going to be a problem because it is an adjustable objective model, but at 800 yards it is maxed out so  I cant adjust it anymore. The further out I get the worse the sight picture gets.  The plan for this rifle is to shoot Coyotes out to 1000 yards.

Notsams - What kind of pressure signs are you having?? Necks, Shoulders or Primer Pockets or ??, Just wondering

How far off the lans are you seating your 80 gn Noslers?? Just wondering....If I get signs or pressure on any of my loads, I will seat the bullet a little deeper (I am talking about .005" deeper and not .05") say go from .020 to .025 as an example) and redo your test....also the most common solution is to reduce your load by .2 tenths of a grain of powder until the signs disappear...I would suggest that you keep track of the number of times your reload each piece of brass...also anneal the necks. I do every three of four times the brass is fired, this is what I do...and over the years, it seems to help with the pressure signs to anneal the brass....and generally with each "flyer" that I have, will single out that piece of brass and look it over carefully when I get home from the range....

On the 308's will never shoot out the barrel on one of those rifles. Am a slow poke when it comes to the loads...I generally start off at 82% to 85% load factor then reduce it from there....until accuracy is archived....finding that 83% works great for the 308's....

Also have a 270WSM with it 26" Kreiger Barrel and Stiller Action, Jewel Trigger, that the loads are near the top of the load chart. I use the 140 gn Accubonds on it and Viht N170 and use close to 63.2 gns of power for it....and it is near 100% load factor...I think 65 gns is 100%....I have notice that on most of my magnums, you have to use the upper % of load factor to get the accuracy you want out of it, and for the long actions like the 270, 280 and 30-06, you have to use around 90% and for the shorter actions, I start off using at my standard 83% and tweak from there....

But every rifle likes what it likes and you have to find that out and it will take much time and many different loads....I don't plan on shooting anything past 600 yards, heck cant see any critters past 400 yards.....but that is my age showing....LOL.....above are just some thoughts....

Keep all of in-formed about both rifles, I am interested in the 22-250 AI.......

 Bo the only pressure signs are the bolt lift is getting harder. If I drop back 1/2 a grain of powder then the bolt lift is real easy. I don't have a way of measuring the distance the bullet is off the lands but it is very close to touching but not touching. I am going to seat the bullet a little deeper in the case but I want to experiment with a faster burning powder too.

notsams, your cartridge length is probably the most important aspects of loading for consistent bullet performance. The hornady length gauges and modified cases aren't that expensive (under 40.00) compared to the information they can give you. If you are still holding your COL at 2.7 you are really jamming the pill into the lands.

I'm glad you recognized pressure warning signs. VERY VERY important to understand this. An 80gr pill at elevated velocity will erode your throat rapidly, just a warning. The density of H4831sc is .0735, if you go slightly slower with say IMR7828 it has a density of .0725 or Alliant RL22 has a .0697 density. I'm sure you also know that the 80gr pill will reduce the powder capacity so be careful not to compress the load. I'd suggest determining the actual volume of your case/bullet and load by density.

Good Points Dutch....on my 243's use either RL22 or 4831 for the 100 gn Pill.....on my 22-250's, using a 50 to 60 gn Sierra GK I use a medium burning powder like a RL15 or H380 in that range anyway....3 out of the 4 of the 22-250's have 26" barrels and the other one has a 24" barrel....use a heavier pill on it and uses a 69 to 77 gn pills and uses the slower burning powder with very good results...Good Points Dutch....Never thought about the barrel eroding the barrel quicker at higher velocities.....

Thanks for the you tube videos for reference.....You tube has anything and everything on it that you need!!! Wow.....Notsams, if you listen to Dutch, you cannot ever go wrong....

Dutch thanks for the great info. what I do is color the bullets with a black sharpie. I then chamber the ammo in the rifle and adjust my seating die accordingly. My bullets aren't touching the lands but they are very close. I plan on trying other powders too but for now I think I will back off about 100 FPS and shoot for accuracy. The gunsmith that built this rifle has 2 powders he wants me to try. Both powders are a faster burn rate then 4831SC. I have been looking on line for load data for the 80 gr bullets but not finding much. My Sierra loading book is all I have for load data. I haven't been able to shoot long range  the last 2 weekends and not this coming weekend either. The rifle is shooting good to 1000 yards and I want to keep going until I run out of adjustment on the scope.

   So I am playing with the AI again. I bought a Burris scope with a BDC type cross hairs in it. I plan on sighting the top cross hair in at 200 yards and then shooting to see where the other cross hairs hit. When I have confirmed where each cross hair hits then I will adjust the turret. Example----- If the bottom crosshair is dead on at 550 yards then I will adjust the turret so The top cross hair "that was a 200 yard  zero" will become a 600 yard zero. Then I will shoot the other cross hairs to see what their new zeros are. I can zero out the turret after I sight in at 200 yards so if I want to shoot under 600 yards I can zero out the scope or leave it and shoot over 600 yards by using the BDC cross hairs.     I don't expect it to work out exactly in 100 yard increments but I want to see what happens. I can have a BDC reticle made from Leupold to my trajectory but not to get to 1000 yards or more. What I am trying to figure is what the difference would be if I adjust the turret about the 500 or 600 yard mark.         I don't care if it works out perfectly in 100 yard increments because the coyotes never stop  exactly in 100 yard increments either.       This isn't going to happen real fast because its winter here but over the next couple weeks I hope to try it.

interesting study. i go w/ the t-plex and turret adjustment just because i don't like the clutter. that said when you are yote hunting, you don't have that kind of time. i completely get what you are doing. i just don't have the open spaces for yotes like you do up there. good luck

    I sighted in the scope at 200 yards and then used the 2nd crosshair at 300 yards.it was 2 inches low. the 3rd crosshair at 400 yards was 2 inches low and 1/4 inch from other bullet. 4th crosshair at 500 yards was 1 inch low and 1.5 inches left of other 2 bullets. 5th crosshair at 600 yards was perfect for height but 3 inches right of other bullets.     It was 15 degrees with light snow and was getting gusty. The wind wasn't effecting my bullets but my hands were getting cold. So now I wanted to sight my top crosshair in by adjusting the turret. My scope is not Moa but instead it's MIL. Each click is 1/10 of a mil or .36 inches per click at 100 yards. "I think"     Then I adjusted up 10 clicks and hit 35 inches low. Then I went up 9 clicks and hit 15 inches low.  7 more clicks up and I hit the bullseye. I was cold and it was snowing harder and gusting more so I quit but I'm excited how it is working out. By sighting in the rifle a little high at 200 yards it will put my other crosshairs dead on at 300,400,500 and 600 yards.    Later in the week it is suppose to warm up so then I will see what happens at 700,800,900 and 1000 yards using the 2nd,3rd,4th and 5th crosshairs.

that is better than I thought. you have to be happy w/ the consistency. all those shots are in the kill zone. nice work

Your exactly right notsams. Here's the math; 3600 inches is 100 yards, 1/1000 of that is 3.6″ and adjusting in .1 mils means we moved the bullet .36″ per click at 100.

Sounds like you have it dialed in pretty close.  Going back to your original 200 yd zero you might be able to center things just a little better with a single click up, but that's about it.  Well done, sounds like the rifle and the shooter are both doing great!
