Thread: Seating tests for 147gn ELDM

I've started by getting some OK groups at 100m at different charges, and am now considering fiddling with seating depth.

A good micrometer seating die is a help. I use Redding Competition seaters which adjust to 1 thou. Also good to set your die so that the press cams over a touch, which gives consistent seating depth. Measure the first couple then the odd one as you go.

And measure from the ogive, not the tip, as mentioned above. Much less variation there.

Cheers

Thanks fellas for the input! Its always really helpful to scour through these tips and try everything. Im going to put 20 across 600y on sunday at Akarana so that will test if things are improving with regards to general scoring / POI consistency. I want to crack 60points if i can

Im really keen to see if sorted bearing surface does factor in when you're using the optimum seat distance.

Sorry to hijack the thread a little bit.
@Spitfire - I set the seating die by winding down onto an empty case until it gets finger tight, as that's what I was taught to do. Do you mean wind down to that point, then half a turn further, or similar?

The first load I did all lengths were suuuper consistent and have not been able to get as consistent since then. Still generally within 5 thou so I have been leaning towards seating further out and incrementally adjusting. It's a particularly frustrating process though.

Thanks again for the help and apologies for the q's.
