Any straight pull hunting rifle really needs a case to full length resized making sure the resizing die makes full contact with the case holder on the ram.
Indeed I would suggest any hunting rifle needs cases full length resized to ensure reliable feeding.
After you have loaded up a batch of ammo, its well worth running them through the magazine and chamber to check they feed well. Any that don’t use for practice.
In my experience, most straight pulls need to be operated with a degree of vigour and speed to feed reliably.
