Any problems running Win. 180 gr PSP in this rifle
The SCAR 17 has a 1 in 12 twist rate. That will not work too well for the heavier 30 cal bullets. As many threads as I've read on the SCAR, it seems to really like bullet weights 168gr and under.
you can fire a 180 gr bullet through it, just dont expect to get top notch accuracy.
Given that you can remove the barrel with the right tool, hopefully someday FN will offer different barrel options.
Ammo I've shot through my SCAR 17s:
600 rounds of Federal Gold Medal Match 168gr BTHP
300 rounds of Prvi Partisan 145gr FMJ
500 rounds of Brown Bear Lacquered Coated Steel cased 145gr FMJ
450 rounds of MFS Zinc-plated Steel cased 145gr FMJ.
Not a single malfunction so far.
