I had two 452's, a Varmint and American(Australian) and while they were accurate, on any given day one would be the better but not the next.
Sold them both to finance a Remington 40XB Rimfire.
Have now purchase a 455 American and Varmint with the laminated Thumb hole stock.
Both are accurate but a lot of ammo testing shows they each have preferences.
About the time you find the preference you run out of that lot number and start over again.
A Minute of Gopher is acceptable accuracy and that is possible with both.
