Re: Powder recomendations 200gr. Accubond 300WM??
In my Win M70 300 mag, factory barrel with the BOSS, I use 69gr IMR4350 and get 2950fps with the 200gr Accubond, seated to mag length - it doesn't matter if it is 80F or 20F outside either. With a 200 yd zero, my actual drops are (in MOA):
I haven't worked on ranges past 400 (yet!), and probably won't until I get a real scope on it.
I worked up to this load, and it doesn't show pressure signs in my gun. I found this load in a very old manual (Speer #3).
As for not having a chronograph, use the velocities that people are listing here to plug into a ballistics calculator, then go out and find out what your real drops are. Mine were different than what the calculator said they should be, some by quite a bit.
These new accubonds are awesome - I was shooting 165gr ballistic tips (3200 fps) with a 100 yard zero - I had to adjust my scope DOWN 6" for the accubonds to be zeroed at 100. I just want to see what they will do to an Elk now [img]images/icons/grin.gif[/img]
I keep nature balanced - I hunt everything!
