Re: Wby Accumark Berger 300Gn Seating Issues
You dont want to crimp, that has to do with die set up. I dont have a 338-378, but loaded a 340 for over 20+. You could single feed as Broz, suggest, I have a friend that carries a few "first shots''. But with seating you should find something to work. A comparator of some type will help you with adjustments. You can do the old fashion, cut channel in top of brass, slot w/small jewlwers or small hacksaw, press in slight to hold bullet. Run into chamber and pull out carefull, that will give length to lands, I use a Sinclair tool for this, but with you free bore most of this is a mute point because you want to fit mag. I load for several Weatherbys, and you just find what they like.
