Lapua's are superb bullets. But that can also be said about Bergers. I shoot both of them
Some find MK's to work for their barrels too.
Following up the pack are the Amax 140's. Rarely are they the smallest grouper but they are consistent and decently priced. Shot alot of Amax's over the years.
These move to the front of the pack if game/varmints are on the menu. Bergers work great on game too. Lapuas have a pretty well established record of not working well on game.
Bullets from 120 to 142gr shoot well. Just depends on what you want to do.
Let me know if you would like to try an assortment cause there is no way to know what your pipe will like until you shoot them. H4831SC seems to be the universal go to powder. Re15, H4350 work great for the lighter slugs. Re17 may be the new powder of choice?????? Hope to test some soon.
CCI BR2 primers get my nod.
The 120 to 130gr bullets are becoming very popular with tactical shooters using 260R because they kick less and fly flatter. Good for those unknown moderate distance targets. More then enough smack to knock down the gongs and plates.
More importantly, their shorter length allows them to be seated properly in standard mags.
The 139 to 142gr VLDs are usually desired for those who want the lowest wind drift beyond 600yds.
More then likely, your barrel will have accuracy nodes for the different weight of bullets so you could have difference bullets for different jobs.
