Taliv yes suppressors are available, as are muzzle brakes. However the rifle I tried out didnt have them, and I wasnt about to go out buy these for a rifle I had only borrowed. I did have an AI rifle on order, which I have cancelled and lost money on.
Ammunition costs a heck of a lot more in the EU than in the US. Taxes are a part of the issue, also they seem to think if ammo is really expensive people would be less liable to shoot each other.
The other issue I had with the caliber is that it induced a huge flinch which would take some work and ammo to get over.
And finally since 90% of the ranges only go out to about 400 meters, it would be a huge overkill. Hence 6.5x47 seems like a better choice.
I have had my mind set on the .338 Lapua for a couple of years, and frankly it has been a bit of a dissapointment now.
