Several come to mind:
1) Ithaca 500 o/u and a BPS Upland Special with 3" 4Buck off a bench to test the pattern.

2) An early LH Rem 700 FS in 338 mag with no scope so about 6.5 pounds.

3) LH Win 70 458 Lott with no scope off the bench.

4) Weatherby 460 with no scope, luckily off hand.

All got my attention and we're not forgotten.
