I have owned almost everything except a 204 I hae never tried it. 7 years ago nothing existed in my world for a varmint rifle unless it said 22-250 and it was a good choice. Since than I have owed and shot 222s 223s, 17s, and than I bought a 243 , 2 years ago, after owning 6mm ppcs and BRs I thought I would try one.
Its better than anything else (22 cals) varmint cals, and you have the ability to shoot accurately at distance 55-107 grain bullets and a better wind bucker. I bought my last varmint rifle in the 243. I was just to stubbern to see the advantages over the 22 and 17 cals.
This year alone, the 243 in a 700 has killed 2 deer with 2 different shooters with 100 grainers and one at a good distance, has taken 25-30 ground pigs at the farm with 70 gr smks and i think 2-3 coydogs this past summer. I have also shot the gun out to 800 yards in 15 km winds with exceptional results with 100 gr bullets. the 243 I bought has been claimed as a hunt camp and farm gun for anything, and I am told its not leaving lol!! I think i need to buy a new one for me. I am not sure if this one was just a shooter, but with a little TLC bedding and a trigger job the gun is just awesome for anything up to deer size.
