I have a 30 yr old 25 MN, and it also doesn't like ANY of the new plastic tipped bullets, etc..

it is great with any 40 grain Load...

that rifle has accounted for about 10 deer in its life time...while serving as a truck gun and dispatching deer that have been hit by a car, out here in rural areas out west..

never took more than 1 shot between the eyes to put a deer down..

more than one were at 100 yds or more out in a field after getting clipped by a vehicle...that Marlin put the bullet right where the cross hairs were at...
