M70s for certain, but I have a custom FN that works the same way with its M70-type safety. Howas are also easy. 98s are easy, if they have the 3-position safety, but few sporters do. Still, the dime trick isn’t too hard to master, but you need something to press against.
Any rifle with a box trigger is going to be subject to trouble. The three 98s I have that can be hunted all have single-stage military types with lighter springs.
