So here's the background: A local businessman has let me hunt and shoot on his properties for years. He takes off to go on hunts all over the world several times a year and his thing is bagging big game. He always has let a local gun store take care of his rifles prior to leaving for a hunt.
Last year he asked me if I would like to tune/zero a rem 700 in 7mm RUM and it took me all of 1 second to think about it and say sure! It turned out to be a fantastic shooter and the guy was very pleased with my help. So he just asked me to tune and zero his Weatherby Mk 5 in 300 Weatherby Magnum for a hunt in Wyoming he leaves for this weekend. Being yet another rifle/cartridge I haven't shot before--I jumped at the opportunity immediately.
I'm using their factory ammo--180 gr partitions which were averaging around 3,280 fps. Stuff is quite good--I got an SD of around 5 fps out of the first 5 cartridges I fired.
I was asked to zero at 300 yds and was told he might use it out to 600 yds. A quick check of ballistics chart shows what I consider a reasonable point-blank range out to about 500 yds.
The rifle is topped with a Trijicon 2.5 x 10 x 56 accupoint; another interesting piece of equipment I hadn't used before.
Long story short--I fired 3 4-shot groups at 300 yds and I couldn't get it to group worth beans, they were about 7 to 8 inches in size. It is a bit of a kicker--but no worse IMO than my savage 111 in 300 win mag which I've enjoyed shooting for years and will easily group sub-MOA beyond 300 yds.
I'm thinking maybe loose rings (they are Weatherby specific 1-piece mounts) but I'm a bit hesitant to go that route since the present set-up is set to his personal LOP/eye relief.
Any thoughts/advice?
