I have 2 of the unmentioned Mossbergs 100atr rifles and these shoot awesome a few hundred rounds down both one in .243 and a 30-06
If you happen to run upon one of those cheap.. I have $250 in the 30-06 and gave a Stevens model 200 in 7-08 for the .243.
And that model 200 is an overlooked gun.. But both of the above are no longer made new that I know of.
I've had three ATR's. 06,270 and 243. every one would shoot MOA at 100. Picked two of them up at pawn shops in the $240 range
