I've tried the 204 twice. Killed some stuff with them and it worked well. Never could like it much although I understand why some like it. Recoil is a non issue if you drop grain weight you gain velocity kinda equals out. Shot 1 barrel out at about 2000 rds. Became a 223
Did not like reloading small bullets with big hands. Needing special cleaning rods , jags, brushes, powder funnel. Always amazed me how many people (not me) need fast twist heavy bullet for everything but are happy with 32--40 grain in the 204.
