Hello,
I was hoping that someone could provide me with some loading info for 180 gr RN Sierra ProHunter in a .308 Win and for a 300 Ultra Mag. Powder type, grains, C.O.L., etc. What ever worked for you would be good (yes, I will use caution with your suggestion). I have Reloader 22 and 19 along with IMR4064. I have checked with the Hornady Handbook but additional info would be good.
Thanks

Mtn Willie -

Welcome. You've found a great site.

Don't use 180's in my 308, as I prefer 150's in it for hunting PA whitetails, but, I have done some load work with 180's and 4064. Start around 41 grains and go from there.

Steve has some good data http://stevespages.com/308_13_180.html
