Shot our first mule deer with this bullet last week at 300 yards. my load is 90 grains of retumbo 15thousands of the lans. 3055fps out of a 28 inch barrel. the bullet performed perfectly.
I personally like to start at 3/4 of max load and work up from there. People have been telling me to work up in 1g increments until you get your accuracy and then fine tune from there. Also good to play with seating depths if your magazine will allow.
I am still playing with the 210g hunting bullets from Berger. 89.6g seems to be close.
