0.050 off lands
they aren't finicky

.050 initially but have migrated to .030
As many others have mentioned these projectiles are not fussy, they like to shoot well.

They are the heroine of bullets. Shoot them and you'll be hooked like the rest of us.
From their website:
The PDR design on the bearing surface has proven to be very consistent and forgiving for the hand loader. Seating depth adjustment for accuracy has been unnecessary, making for much less time spent creating an effective load. Load development is as easy as shooting for velocity and then confirming point of impact.

In a post on Hammer Time (link below), Steve states that he starts with the longest COAL that will function in the rifle and seat ,020" off if that COAL contacts the lands. Also states that when a rifle will not shoot 1/2 moa, he seats deeper in intervals of .015".

@Ingwe asked me if I would start a thread detailing how we do load development, so here goes. With a rifle that is new to us the 1st thing we do is clean it until there is no copper from other
I like to go mag length minus .100" if I'm limited by mag restrictions. If there aren't any restrictions, I start about .050" off the lands.
I've had a few guns that needed some extra adjustments to get best groups, but I'm typically around .5 MOA without adjusting seating depth. One interesting observation I've made is that the 6.5mm bullets have been more sensitive to seating depth in my guns (3 different rifles) coverings 3 very different performance categories. The 338s have been the least sensitive.

I have tried a couple of types of hammers in my 6.5 creedmore and have not been successful in getting them to group under an inch. Velocity has be great and with no pressure signs at all with various powders and primers. Since my first hunt is less than 10 days away, I will hunt with what has worked best and resume the hammer experimentation again next year with more seating depth trials and powder recipies. So far, the only seating depths I've tried are .05 and .025.
Agreed, I load the 174's at mag length for my Tikka T3X
in 300 WM which is about .120" and they shoot 1/2" or better.
Really not necessary
Has'nt been for me. I seat most of mine to the PDR ring closest to the nose for crimping and that's it. My 257 Wby has such a long throat and magazine I actually crimp on the 2nd groove with it (gives extra room for powder too
).

For you guys who crimp; are you crimping over a PDR shoulder and curling the brass inward? Or are you just crimping on a bearing surface to increase tension?
I crimp over the depression of the groove but with the lee fcd I don't think it really matters cuz it'll crimp a smooth bullet like an accubong just the same.
