FX King Synthetic

Must have missed it thanks for letting me know
The ST chassis is really for competitive shooting so I am not really a fan I think the new sythentic stock is much more practical I have some for my Crowns. I think it makes more sense for this rifle than the GRS one so much so I may get a King now. Also adding a $700 ST chassis to $2,400 gun never made much sense to me unless you serious about trying to win some money which is not me :)
 
How will would slugs shoot out of the 500mm generally speaking?
I think you would find some that would do ok. Lighter weight slugs. I believe the 500 has the latest standard (non heavy) fx liner in it. Seems .22 caliber would be the best choice for shooting slugs out of the 500 mm gun.
