Round count about 2,000 with standard load Winchester and UMC ball ammo. Still accurate and functioning 100%. The "fanning" you see deeper in the barrel is artifact of the digital image. Does anyone have an idea about what is going on here? See the attached pictures. Thanks for your consideration, Mark Attachments Edited by Eagle Eye (07/30/26 09:21 PM)
