Like my 25-06ai with a 1-8 twist. Started with hammer 103 hh. Had plans to shoot 133 Bergers but the hammers shot so good I have not tried anything else!!! Used retumbo for powder.
I’m using retumbo with Berger 135 classic hunters with very tight groups! It is my coyote gun so that is why I am
not shooting heavy bullets. Winchester magnum primers tighten up my groups compared to cci250s.
