bullet seating psi

[williepete]

Just got in a 21 century hydro press and started seating some bullets
what would you say is a acceptable difference in psi

I went back and searched the forum and found the info that I needed
from back in 2020
one thing for sure this is a great tool and will teach you a lot about your brass prep
It is well worth the price of admission.

i dont think there is an optimum, just as long as your reloads
are consistent psi. Neck tension used will dictate how much psi you need.

Consistent psi is the key
from what I have read from other shooters that use this press are saying that
any variance above 5 psi shows up on paper
that's what I was looking for
but thanks for the reply.

Man. I use the Lee Collet Neck sizer for 6.5cm. Lee dies have worked good for me for the most part, but they're low cost and cheaply made.

Anyway. I think the collet would stick on occasion because I'd get bullets that seated so loosely I could pull them back out with my bare fingers.

I went to double neck sizing on the same die and saw a great improvement in felt consistency. I run the K&M Arbor without the dial, but it gives a good feel on consistency.
