I have been reading through this thread but it’s going to take awhile before I get all the way. It seems you have a lot of experience with both 22 cal and 6mm’s. I currently have rifles chambered for both but I’m looking at picking up another one with a faster twist to shoot heavier for cal bullets. In your opinion would I be better off going with a .223 or going with a fast twist .243 or 6 creed. It will be an everyday truck gun and get used for everything from varmints to coyotes and shooting steel. I may do some deer hunting with it also.Something’s should remain quiet.
