don't know if this right place to post this but here it goes. rifle is a single shot 22 hornet that looks like a big rimfire action. 30 percent or so of factory remington ammo fails to extract. extractor slips over the rim leaving me with a small screwdriver to remove case. bolt also feels kinda hard to close. have reloaded a box of the fired brass but have not made it back to the range yet to try them. have some winchester brass also but have not fired any. the rem ammo is the only ammo shot so far. anyone else have any extraction problems? thanxs, vic
