[QUOTE="aushunter1, post: 1719661, member: 57533"] You shouldn't have to many troubles with what you are thinking but you would need to check stabilization/twist rate charts of the projectile you want to use. 90gr is up there but stabilization isn't so much about just weight, its about the length as well. I use a load in my 1:14 with a 70gr Speer without issue & even though it goes against all charts for a 1:14 it works due to the length! [B]Speer Bullets 22 Caliber (224 Diameter) 70 Grain Semi-Spitzer[/B] [B]Technical Information[/B] [LIST][*]Caliber: 22 Caliber[/LIST] [LIST][*]Bullet Diameter: .224"[/LIST] [LIST][*]Bullet Weight: 70 Grains[/LIST] [LIST][*]Bullet Length: 0.808"[/LIST] My usual projectile is this one, you will see the length for comparison [ATTACH=full]150887[/ATTACH] Also just be aware that if you do go a 1:7 if you try to use 40gr in it the projectiles could very well disintegrate as they exit the barrel due to excessive spin? On a side note, there are a few factory offerings by some manufactures in 1:10 & 1:9 but they are few & far between. If would be great if manufactures would offer the .22-250 in 2 different twist option like Tikka does with the .223! [/QUOTE]
