200g sierra HPBT #2231 question

[smokin502]

I bought a box of these newer matchking bullets for my 300wm to try out. (Have a lot of time as of lately) Looks to have a good bc at 715. The problem is, it looks like there won't be much actual bearing surface inside the neck of the brass for seating. Has anyone shot these yet from a 300wm?

Old post but I am curious if you ever developed load data and if so, how they shot?

I started to but stopped. I didn't think they would stabilize with a 1in10 twist. They also would hang very far out of the case neck for a .010 or so off the lands. They also would definitely need to be single feed. That one I really didn't mind. Using quickload I compared them to the nosler 210 gr. There wasn't any advantage. So I'm using the nosler now.
