Bullet seating depth's for rifle barrel node

[Eyefor]

Thanks very much Eyefor for this ---------------so if i load at 34.5 then alter the seating length by 5 thou over the minimum to maximum seating length your saying some where along this i will get 1/2 group.

Start at 5 thou off the lands. Then working from that reduce that in 5 thou increments until you find a decent (sub 1") group. Don't stop at the first decent group, there may be a better one. After finding the best length then tweak the load to make that sub 1" group to be 5 holes touching.

Is that meant to say 0.2 or 0.3 Grn increments?


Dave,

Some bullets just will not work in a particular rifle.

I must have tried 30 different bullets in my .223 and some of them will make tiny clusters all day long, but some just will not settle down, no matter what.
I found the same bullet issue with my .308 staking rifle only without the objective of making tiny clusters.

DEFINITELY .2 or .3 increments. SORRY(and thanks). Post edited.

I agree re bullets and found Sierra 1360 best in my 22-250
