300 wsm which bullet for elk and deer

Are you guys initially shooting groups at 100 or 200 to find pressure. I as well will be working up a 166 HH in the next few weeks. I was gonna try rl17,rl26 and 4350

100 yards is what I do. Start somewhere around 5-10% below listed max for what powder your working with and work up in 1 gr increments until you hit pressure then back off 1 grain and shoot a group. Hammers will not show pressure as soon as traditional bullets and usually you will be over listed max powder charge. Load to your longest coal weather it's to the max mag length or .02-.05 off the lands. They are not very sensitive to seating depth in my experience. I've found 1/2 moa loads with under 15 rounds in load development.
