Even tho I shoot a lot of 223 rounds, if truth be told, give me the 22.250.
it is not a 243, but it is a notable step up from the 223, Especially the one I have with a one in 7 twist barrel.
on that one, I use 75 gr BTHP and 80 grain A Maxes...at 3350 fps MV.
Pretty flat shooting also out to 300, and doesn't need much adjustment to stretch it to 400 easily.
