Not really a Semi person BUTT the Winchester 74 are very accurate as well as Full size--Unique in the fact that they can be cleaned from the rear
The T/C 55 is very accurate
Remington 597 are another good option
All three of these rifles will average less than 1/2" at 50 yds and not break the bank when purchasing
Good Luck
Jim
Proly with Thunderbolts or Wildcats too.
