if you want to get serious about timber hunting, I think it’s great - the more you do it the better you’ll get!
Out at 400 yards few lever guns or red dots are up to it.
A lightweight 30-06 with 1-1/2x to 5x would be hard to beat. My timber rifle has usually been a 338, but we also have grizzly bears.
Shoot 10 rounds off hand and sitting each week for a year and you’ll be better prepared than 99% of timber hunters. Get fast at dropping into a sitting position for those quick 150+ yard shots. In the timber everything happens quickly and a mental shooting checklist that’s quick will mean the difference between elk and no elk sometimes. Get the idea of shooting prone, adjusting parallax, ranging the distance, and dialing elevation out of your head. Keep the scope caps off. To at least 250 to 300 yards, see elk - bang bang!
Focus on a rifle that’s easy to hand carry and keep it in your hands as much as possible. Compact 7x binoculars used without a case are ideal - being able to quickly bring them up one handed means they get used a lot. Forget fumbling with a big chest glove box and binoculars that have to be held with both hands.
Remember to go fast until into fresh sign, then go slower than seems natural. If all you see are elk asses way out of range, you’re going to fast.
There’s nothing more exciting than coming up a bench and smelling them before you see ‘em!
