I had a Weatherby LW Accurmark and then a custom Model 700 in .240 Weatherby. Also had a custom Model 7 in 6mm/284. Shot 90 & 95gr bullets only. Well, I did load 50rds of 70X in the Accumark. Its a great killer and I have a friend/chuch member here that has used his Mark V in .240W with the Nosler 95PT over 40yrs, deer, elk. I didn't find the Weatherby brass hard to work with, just to find! The 6mm/284 was the same thing, but lots of case prep. I like it, always used R19 in mine. My friends uses 4895.
