The wife bought me a model 12 VLP for a Christmas present. Gun has 1 in 7 twist so I started trying some 77 and 80 gr nosler cc,s. They shoot great but must be loaded manually into the chamber. The magazine will not kick them into the chamber. They strike back of barrel, center but too low to enter chamber. These rds are longer than saami specs but are NOT too long for magazine nor are they too long for chamber. They shoot fantastic with mv about 2825. What needs to be done to get the mag to kick the round into the chamber? Never seen this problem before. Thanks Daniel hi
