. .400 CorBon is among the best. I am interested to hear CGNers experiences.

i have a pet load for 155 JHP, starline brass, 9.5 grains WAP will shoot way better than i can. mine is a brilli bbl and a crome 21 pound spring. functions and works flawlessly. i know this is a mid level load, and when i first got it, i played around with lots of diff bullets , weights, and powders. this combo however seems to shoot the best in mine
Have you tried a separate taper crimp die? - dan
If you take advantage of the larger (than 40) case capacity to attain high muzzle velocities you will need a heavier spring to match the load, but from what I understand in open you would be using the case capacity with a somewhat slower powder so the gases have the desired effect on the comp... Open-gun don't jump, 160 PF but lotsa noise so you shouldn't need more spring(I believe some even use lighter IIRC).
Roll crimp sounds interesting.

a bit of a necro post, but I finally made it.
producing non setting back rounds is possible.
-taper crimp die: no good
-no case expanding: no good
-round nose bullet: helped but not miracle inducing
-reduce power of spring: does nothing but help achieve desired power factor (see this is where our loads differ beater, I now use a #9 spring because my charge is mild but all power is dissipated in the compensator)
Then I finally decided to order a cannelure tool to roll crimp, and it did a world of difference. I wouldn't say I reduced setback to 0, that would be a lie and even straight walled cartridges are prone to bigger than 0 thou set back.
What I did achieve though is a setback between 0,0005" and 0,002" upon chambering, very good compared to the 0,010''-0,020'' I initially had. Biggest cons is having to sit at the bench to put a cannelure on the bullets, but it is a faster process than I would have expected
