"Personally, and no offence meant, but I think the .224" calibre (in its .222/.223rem for) to be a bit lightweight for deer. The light bullets & small wound channels leaves no margin for error."
Anyhoo - it's legal, so aim straight & good luck!
This is interesting I am ready to start using my 243 on roe but so far with the results from the 223 I see no need? but I have not shot enough Roe for complete proof with each caliber. I presume you have extensively shot Roe with both calibers to decide that a 223 is a tad light? may be the 243 would extend the confidence and range but I am only after a few for the table each year so can pick my shots. I only shoot 20 to 25 a year.. .........but let me tell you out to 170 meters 223 is a killer on roe!
