[QUOTE="MagnumManiac, post: 198710, member: 10755"] Didn't I say that my powder measure is accurate to within .1 gr? My Redding powder measure is very accurate,even with heavy stick powders,although I have to keep an eye on the hopper level,charges have a tendency to increase as it empties. My chronograph also shows that if I 'trickle' to exactly the weight I want,or use my measure,there is no practical difference in extreme spread until .5 grain +/- is reached.With loads either thrown or weighed,I have found that the velocity difference can be held to +/- 25fps with both techniques.Velocities in even tuned rifles can deviate more than this shot to shot,so the trajectory differences are there anyway.The biggest difference made to ES was powder packing scheme,as thrown,or 'swirled' into the case with a funnel,this method reduced ES further which gave only a +/- difference of 10fps.I do this for 600yrd shooting with very good results. I know most of the bench resters here ONLY use a powder measure,of course they still 'check' every 10th load thrown on a scale. [B]MagnumManiac[/B] gun) [/QUOTE]
