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.
