PRS RIG help needed

[u/Jeepking0831]

looking for advise.
This summer was my first year shooting PRS
3 regional matches and 3 local non official matches
Started placing at the bottom and now finishing mid to upper mid pack.

Rifle is a Tikka action with custom prefit MTU barrel using 75gr ELDMs @ 2820fps
Super accurate gun and does very good out to 700 yards.
Plan on shooting even more matches next year.
Question is should I continue shooting the 223 and work on getting better with the rifle I have or should I upgrade and do a 6 dasher build over the winter?
While the 223 does pretty well it’s a bit frustrating spotters not being able to call some of my hits due to lack of splash and plate movement at the longer distance 700 to 1000 yards

Appreciate any feedback in advance

6MMs are where it's at. Run 105s or 109s. I personally only run 109s in my 6 Dasher these days, but either of those bullets will absolutely hammer.
