They claim on their website that it is easy to develop a load with their bullets, did you find it so?
Yup!
These are long bullets.
Seating depth is essential to be on the lands.
Must have a minimal of at least 3 ribs in the case neck.
If you can load to .10-20 off lands great
If not don’t worry about it.
Go to your loading manual.
Find a powder in the medium range.
Load powder until it just touched base of bullet.
(Basically crush powder in case then back off a few grains.)
Keep repeating process until you don’t feel/hear powser being crushed.
Put that load on the scale.
Confirm with loading manuals it doesn’t exceed suggested hot load.
Mine was nowhere near hottest load.
Then load as many of those bullets as you’d want to test for accuracy.
Load -.3 grains as many as you want to test.
Load +.3 grains as many as you want to test.
No surprise to Steve my most accurate load was the one that just touched the base of the bullet.
