FX FX King 30 Cal 600 mm Tune

[Archer40]

Hello all,

Im trying to get some info on a good tune for the King 600 in 30 cal. Ive been shooting ZAN 52's at 940 fps and its doing pretty well but Im wondering what other slugs anyone else is shooting and with what tunes and accuracy results.

Im at 160 on the reg with the Micro at 4

Thanks in advance for any info.

interestingly. I shoot 52.4 grain slugs from a dynamic 700 .25 but I use an 8mm hammer at a setting of 155 bar and a micro 3 at 289ms. in 30 caliber with a 600mm long barrel it should be somewhere around 145 bar at your speed. the basis of both airguns is exactly the same

I have Crown MK2 with heavy hammer, its not King, but very similar. 600MM 1:22 liner, shoot 43 and 47gn NSA slugs, very good results at 150BAR reg hammer spring on 14, 905FPS, 50 yards 10 shots one hole.
