If you are looking to create a training round that simulates the performance of the Imperial Meeting ammo then you should choose the 2155 or Nosler Custom Competition 155 (if you choose a more 'efficient' bullet you may find you are under-calling the wind when it comes to the Imperial meeting). Otherwise I personally use the 2156 (not a fussy bullet) but the Scenar would be just as good a choice. Also consider the HBC.
I wouldn't buy expensive new Lapua brass. Once fired brass can be had at a fraction of the price of new. I have never bought a new case, and will never need to, and my second-hand brass won me a *lot* of TR trophies last year. Properly processed it will last a long time, so why pay 5 times as much to (just maybe) get an extra one or two firings and no performance benefit? My 1st choice would be once-fired uncrimped GGG .308 if you can find it.
Consider RS50 powder. If bought in bulk it's possible to get a very competitive price; it is readily available. batches change infrequently and there is little batch-to-batch variation when they do. I used it exclusively for TR in 2017 and won a few open meetings outright and achieved top 3 placings in several others.
Dies:
Seating: Redding Competition seating die or Forster Ultra Micrometer seating die.
Sizing: I suggest 2 options for sizing dies, based on different approaches to controlling neck tension, both assuming you will not neck turn:
1: Redding Type S FL Bushing die.
2: Any good quality 1-piece FL sizing die, followed by a Sinclair expander die with PMA tool .307 carbide expander mandrel.
I use the second option, and prefer to avoid bushing dies, but either should work fine.
Other:
If you do buy fired brass then get a Redding Small Base Body die.
A universal decapping die is always useful.
