I was wondering if anyone out there has taken apart one of these factory loads.  I figured I would try and save myself $50 and ask you folks first. Any idea on type of powder and how many grains? Thanks to all.

in noslers new manual they show that with said bullet that vihtua vori n550 is the most accurate powder they tested and 61gr was there most accurate load. i myself had very good luck with r-19 with the 300wsm and 180gr bullets. each rifle is different though

Thank you for the post.  I looked at the nozler info the other day, which brought up my question.  The Win Supreme 180 accubond claims a velocity of 3010. When looking at thier load data you can see that there most accurate loads are well below the 3000 mark with the w760 and the imr4350. RL-22 is the closest to the 3000 mark as far as there accuracy test goes.  What kind of powder do you think they are putting in that Supreme load? I have the accubond bullets and have not loaded any up yet. I curently shoot speer BTSP and have had great success with them on paper. I would just like find out this info before I start the process. Thanks again for the post.

So far my most accurate powder out of my rifle is 4831SC.  I am still waiting to give the RL-17 a try if I could ever get a hold of some. 

Pyro, What type of primers are they using in your manual with that load?  Thanks
