I have 34 rounds of Winchester Super Speed 257 Roberts ammo for sale. I am not sure how old this ammo is, but it is in very good condition and will come in plastic boxes as shown. As far as I can tell from searching on google, this ammo is 100 grain. I have searched for prices on this caliber ammo, and it seems to be in the $1-$3 per round range. 34 rounds + boxes for $25 OBO. Trade for .45 acp, or .223/5.56 brass cased. I live in Hillsboro, and work in Clackamas, so meeting anywhere in or between those areas is good with me.
