Have never tried the AI but I do have eight 225s.
Two WIN model 70s---1 standard and 1 bull.
The standard will out shoot the bull any time, three under a dime at 100.
One WIN model 670, have never shot it.
Two H&Rs, one is an old Pardner 22 JET rechamber.
I don't have a frame it will fit.
The other is a SB2 223 rechamber which I just got with a 1 in 12 twist.
So far about 3/4" for three at 100.
A 28" custom ENCORE by BULLBERRY.
Three under a dime and five under a quarter at 100.
The last one is a Custom REMINGTON model 30 S EXPRESS I had built to my specs.
This one has a 28" PACNOR (spelling) #5 heavy sporter barrel in a custom stock.
If I do my part it will usually keep 5 completely under a dime with at least 3 cutting at a 100.
These are all with factory ammo.
I do reload but just never got around to the 225s.
Might have to before to long as my supply of ammo is down to about 5 or 6 hundred rounds.
I use this caliber a lot!
I would like to have one done in an AI.
With 50 to 53 grainers it should match the 220 swift or better.
Might have to check into that.
Let me know when you get yours done.
Looking forward to a report!!!
Good luck and I hope it's a shooter!!!
