300WM Bullet movement question

[Ballistic Artist]

When you neck size cases with a bushing neck sizer (type S Redding) for a 17Lb 300 WIN MAG, and dont crimp them, will recoil cause the bullets in the mag to change case OAL?

Doubt it, but there is only one way to find out

Well, when I neck size for an 8 lb. 300 Weatherby Magnum the bullets don't move under recoil.

Give it about .003" of neck tension and you should be fine. It;s what I use in my 300WM and never had any troubles.

I would never crimp a match bullet.

No, I run 0.0015" neck tension on my TRG42 338LM and it is lighter than your rifle.
