I would say - If other 6.5 x 47 Lapua guys aren't having an issue, then it's gonna be alright. That's a pretty established cartridge, now, and Lapua put their name on it. There's no way it doesn't function, as a developed load/cartridge, by Lapua.
Here's good info on "the 3," 6.5 x 47 Lapua vs. 6.5 Creedmoor vs. .260 Rem.

If it was me - I'd build a .260 Remington. I can make the brass out of .308 Win brass, and I reload. That's what seals the deal for me.
6.5 Creedmoor is based from the .30 TC brass - and finding that is hard, if I wanna convert it, or I buy it (Hornady brass a a buck a round).
6.5 x 47 Lapua is not gonna give you a "parent-case" brass choice - because that's it. You pay buck-30 per round, new brass? That's not bad. My new Hornady Grendel brass is $40-per-50 pieces. All new brass is expensive, Lapua being a little more.
Even though the 6.5x 47 :Lapua will go 1000 yards - that's not what it was designed for. This is a quote from the article I linked above:
There's alot to think about before getting into this cartridge...
