Just reloading some 300 prc. Checked stock Hornady ELD-M, they are about .040 off the lands on my chamber, fairly consistent. Is .020 a good place to start on my reloads?

What distance are you shooting?
How are you loading? Single shot loading, magazine fed or something else?
In my hunting rifles, whether custom or factory and within 600mtrs, I don't load any closer than .010", even my small varmint cals. Dust, dirt and other anomalies that can booger up a rifle probably will in my experience.
The Brian Litz bullet jump test has always proven itself to me, the only time I jam Bullets or kiss the rifling is with dedicated target guns. This is sometimes necessary, but not always.
Anyway, .020" is as good as any other measurement to start testing at.
Cheers.

Like L.Sherm said, I like to start closer. Usually .010 off (but further with monos). Berger Seating test has proven itself to me. If I am going to mag feed, I'll use .010 or mag length, Whichever is shorter as a place to start.
I prefer to start with a light touch to find pressure, then adjust searing depth to tune the final load.

It is a target rifle only, shooting to 1K. It is a Ruger RPR with a 5 shot mag. At .010, would be just under SAAMI length. Good place to start.
