I'm going to start loading a .300 WSM for a freind to get his groups better at range. Looking for some load data. I think I will start off with Barnes trip shock 180 gr. and would lke to use H1000 powder in front of Fed 215 primers.
Looking for a start load and max load so I can do 1/4 gr steps to tune in the rifle for best group.
Also what # shell holder (RCBS) for the case. I have a ton so told him not to buy one until I check to see if I have it.
Rifle is a stock Weatherby Vangard. Very nice shooter. He was able to take a cow elk @ 550 yds on his first hunt with it factory Fed ammo. One shot and down. His eyes were the size of paper plates when I told him the yrds and where to hold.
