I am new to the world of reloading and am looking for a little guidence from someone who may have experience with reloading for my rifle or something comperalbe.  

What I want to do is start developing a custom load form my DPMS LR308.  The best accuracy I have attained are from Hornady 168gr A-max ammo and from Federal 168gr Sierra MatchKing BTHP.  I am looking to develope a comperable load.  

What I was considering was Hodgdon Varget powder and Federal 210 primers with either the Hornady or the Sierra bullets at 168gr.  I am really unsure of a good load to start with as far as the powder is concerned, I had in mind 40grs but am unsure.  If anyone has some advice they would like to share with me, or any proven loads for this rifle, it would be greatly appreciated.

check the 6mmBR.com site. look on left side of main page. It will have 308 information.

If you have the bull barrel seat your bullets out as far as they will reliably feed and fit in the mag.  also try 180gr sierras. I'm assuming you have a 10 twist. Varget is good RL15 and 4895. 40-41 is a good place to start.
also secant type ogives usually don't work the best nor do VLDs with a standard throat.
Sierras are much more forgiving.

just my opinion

You are on the right track. Start with 40 prs of Varget and work up. You'll likely find smallest groups at 41-42 grs.

48 grains H380 Nosler 150 ball. tip the Chuck Talyor load and it works great it replaced for me 46 grains RL12(disconuted) 150 Sierra FMJ BT.

I guess my main concern is not blowing up my rifle.  So what I have in mind should be a pretty safe starting point?

180gr matchkings and varget is what shoot best in mine.  175gr are close.  varget likes the cci benchrests if you can spring for them.  start at the min load and work up.  the loads will pattern, vert string, then group tight.  work up in .3gr; then when you find a good one, work around it with .1gr increments.  make sure you have a good scope mount, rest, and trigger.  i test for groups with 10 rounds of each charge.  five at 200/300yds each, then again to be sure.

I've also heard to use Winchester primers on M-series semiauto rifles due to the firing pin being free-floating. The winchesters are supposedly harder than regular. There is a risk with non-military primers there could be slam-fires?

I know it's a risk on my M1a/M14, but does this apply to the ar-10 platform?

He is correct. The only ones that are really soft are Federals but I haven't even had any problems with Federals in my DPMS

I have a Lee reloading press and the Lee Pacesetter die set, a scale, a tumbler, and a case trimmer.

What is the usual case preperations that you guys usually undertake during reloading, and what special equipment is needed to do this besides what I have.  Just looking for a little extra guidance on this one, thanks.

Read, read and read some more. The ABC's of Reloading has been highly recommended on this site. I suggest you spend some time researching before you make any attempts at reloading. BTW this site has a very good reloading section.
