I just put together my first 110 build (22-250 barrel ) and after setting the head space using the correct gages and I've been checking to find the lands location using a modified 22-250 case and all my measurement are right at 2.5 inches.....which seems extra long according to the specs I've seem for 22-250. Is there enough case neck to even hold a bullet if the lands are that distance? The barrel was used so does that mean it's wore out? my cases are new never fired. Any help is appreciated.
