I had a 550 american in .243.
Shot real well. But I sold it as I did not want to lug around an 8 lb .243.
I would love one in 9.3X62 or a 7mm Rem mag.
I would like to see them build one in .375 and 416 ruger.
I did,nt mind the set trigger on the .243 But I would change it out on a 9.3X62 or If I bought a dangerious game rifle.
Simplicity is what i want in a hunting rifle. Fewer working parts means less chance of one breaking.
Timney makes a trigger for the CZ 550...tj3006
