Re: Need some advice
Well, I'm not claiming to know more than many on this site, but I'll give ya a response.
One thing you may want to focus on is seating depth and get yourself a Hornady Headspace guage to measure how far you seat off of your lands, also the hornady coal guage kit. all you need to be able to measure is .001" but these guages fit on a caliper and make the job alot easior to be consistant from lot to lot.
I believe that you measure bearing surface by measuring the distance from the ogive to the base of the bullet using a COAL guage and a caliper. I think you still only need to be w/in .001" (I'm just getting started doing this).
I am also a believer in getting a primer pocket uniformer and a VLD inside neck deburing tool.
Sorting brass is something I do, but many don't beleive in it. I did a little research and I am assuming you are loading for your 300 dakota rifle so I am not familiar with the quality of the brass. All you have to do is resize, trim, inside primer deburr, uniform primer, outside deburr, inside neck vld debur, then you weigh the brass and sort according to weight.
Also, depending on your headspace on your rifle, you may want to partial full lenght resize to help save brass life.
I used to re-load but now I "hand-load".
