Seat to your chamber. Ignore SAAMI overall length, it's way short, those bullets are seated ridiculously deep. Ignore what it says in a manual. I don't think there's any other cartridge where the caseneck is well past the ogive. That length wasn't chosen because it's most accurate, it's because factory ammunition has to fit any magazine for any rifle chambered 22-250. My chambers are 0 freebore and seated to just shy of the lands, overall cartridge length is still much (much) longer than 2.350. Trouble is with a factory chamber it's difficult to get near the lands and have any bullet in the neck. So you have to find a happy medium. With 0 freebore I seat .005-.010" off the lands and get superb accuracy. But with a factory chamber, if you can find the lands the bullet will be seated much further out. The bullet really only needs to seat deep enough for the neck to hold it very straight and secure. Start as close to the lands as possible with enough bullet in the neck to hold it well, and see how that goes. Every chamber/barrel combination is different and has it's own happy spot. You'll have to find what's best for your gun.
