Test fired 5 rounds of 110 grain nosler with 43 grains..... very rushed lunch time test and forgot both my sling and the rifle rest so this is just elbows on the table. center hold sights on 200m from last time out. First shot always goes wide with this rifle ? Like the M1s so for the conditions I will take this group.....pictures in a few. The rear notch is tough for me to see clearly. I have Corrective shooting glasses so I can see the front sight and I tend to shoot rifles with rear aperture style sights not notch and post.... If I use my glasses that I can see the rear sight I loose front sight focus....so much fun. not to bad for my eyes and rushing. should be just fine for pembroke vintage match.
